Storm Updates: Quiet Pulse, Northeast Flood Slight — Sunday, September 27, 2026

This is a live Sunday afternoon snapshot of U.S. local-storm activity as of Sunday, September 27, 2026. The organized severe desk is quiet. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook states no severe thunderstorm areas are forecast and organized severe storms are not expected through early Monday. No convective watches are valid. Restoration exposure this afternoon is leftover nor’easter wind and water on the coastal Northeast, isolated gusty outflow from north Texas cells, and urban ponding where WPC keeps a Slight excessive-rainfall risk from New Jersey through southern New England.

These are county-scale thunderstorms and a fading coastal cyclone, not a mainland hurricane landfall. Conditions change. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

SPC issued the 2000 UTC (2:57 p.m. CDT) Day 1 outlook with the categorical line removed. The morning Marginal over western Nebraska and the Black Hills was taken off earlier; this cycle made no further change. Isolated convection was ongoing across portions of central and north Texas near 1945 UTC. SPC notes an isolated strong or damaging gust cannot be ruled out given steep low-level lapse rates and moderate buoyancy, but weak lower-tropospheric flow, limited effective shear, and poor mid-level lapse rates keep the severe probability under 5 percent.

A few additional thunderstorms remain possible late this afternoon and evening along a diffuse surface boundary from north Texas into southern Oklahoma. An occluded cyclone continues to weaken near the northern Mid-Atlantic coast, with elevated convection and isolated lightning possible to its northeast across southeast New England. Elevated storms over central South Dakota this morning were described as already past peak.

Weather Prediction Center Day 1 Excessive Rainfall Outlook (valid 12 UTC Sunday through 12 UTC Monday) holds a Slight Risk of excessive rainfall for parts of the coastal Northeast — New Jersey, southern New York, and southern to central New England. Additional rainfall of 1 to 3 inches, locally heavier, is the language over the NYC metro into eastern Massachusetts. A Marginal Risk covers parts of Upstate New York and central New England, plus a separate Marginal from the Texas Hill Country into south-central Oklahoma. Isolated low-end flood potential is noted over portions of northern Arizona as moisture associated with Hurricane Polo begins to lift north of the Mexican coast.

High Wind Warnings that covered Eastern Monmouth and Coastal Ocean Counties in New Jersey and Long Island and adjacent Connecticut zones were in effect until noon EDT Sunday. Those products have expired. Tree-and-wire work from the overnight gusts is a just-hit desk, not a live warning desk.

Hotspot 1 — Coastal Northeast flood slight, wind fade

The live organized threat here is water, not a new severe watch. The slow-moving nor’easter lingering near northern New Jersey and eastern Long Island is still funneling moisture across southern New England. Instability is low, so instantaneous rates are not the main story. Saturated soils from coastal inundation and prior heavy rain keep urban streets, poor drainage, and small streams in play.

Cities and counties to watch: New York City and Long Island; Eastern Monmouth and Coastal Ocean Counties, New Jersey; New London and Middlesex Counties, Connecticut; eastern Massachusetts including the Boston metro. Restoration read: extraction and drying from last night’s wind-driven rain, plus ponding calls if the Slight Risk verifies. Photograph roofs in remaining daylight only if it is safe. Do not treat this as a new High Wind Warning — those expired at noon EDT.

Hotspot 2 — North Texas into southern Oklahoma scatter

This is the only convective corridor SPC is still talking about on the afternoon update. Isolated cells were already up over central and north Texas mid-afternoon. The same diffuse boundary can support a few more storms into southern Oklahoma this evening. Gusty outflow is the listed hazard. Hail and tornado probabilities are not highlighted.

Cities and counties to watch: the Dallas–Fort Worth periphery, Waco and Temple corridors, Wichita Falls, and counties along the Red River into southern Oklahoma. WPC’s Marginal excessive-rainfall pocket from the Texas Hill Country into south-central Oklahoma is the flood overlay on the same air mass. Restoration read: isolated wind and brief heavy rain. Staff local Severe Thunderstorm Warnings if they fire; do not staff a regional outbreak that SPC has already declined to draw.

Hotspot 3 — High Plains leftover and northern Arizona moisture

The morning Marginal for large hail over western Nebraska and the Black Hills is gone. SPC says the central South Dakota convection has already peaked and that any overnight elevated storms from western South Dakota into North Dakota carry only a low isolated-hail threat. NWS Aberdeen did issue a Severe Thunderstorm Warning this morning for parts of Stanley, Sully, and Dewey Counties, South Dakota — 60 mph gusts and quarter-size hail, radar indicated, until 10:00 a.m. CDT. That product is expired.

Northern Arizona is a low-end flood mention only, as flow turns southwest ahead of a trough digging into California and begins to draw moisture associated with Hurricane Polo. Polo itself is a Baja California Sur hurricane, not a U.S. mainland landfall. Restoration read: check whether any local flash-flood warning is actually live before rolling a crew. The outlook language is not a warning.

Just hit

SPC today’s storm-report page for the 1200 UTC Sunday through 1159 UTC Monday window showed no tornado, hail, or wind LSRs as of this afternoon scan. The morning desk already logged overnight Comanche County, Oklahoma wind and quarter hail from Saturday night. Mid-Atlantic High Wind Warnings that ran through noon EDT Sunday are the other just-hit pile: trees, service drops, and coastal water intrusion on the Jersey Shore, Long Island, and southern New England.

That is ticket work already on the books, not a new watch. Hurricane Nolo remains south of the Hawaiian Islands and is not a CONUS landfall. Hurricane Polo is a Mexico / Baja desk. Tropical Depression Fay is well west-southwest of the Azores. None of those systems is a U.S. mainland hurricane landfall this afternoon.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
Coastal Northeast (NJ / NYC / southern New England)	Urban flood, leftover wind damage	WPC Slight excessive rainfall; High Wind Warnings expired noon EDT	Live flood slight / wind fade
North Texas / southern Oklahoma	Isolated gusty outflow, brief heavy rain	SPC no severe area; WPC Marginal flood (Hill Country–south-central OK)	Scattered cells
Western NE / Black Hills / central SD	Isolated hail earlier; now quiet	Morning MRGL removed; SVR warning expired 10 a.m. CDT	Quiet
Northern Arizona	Isolated heavy rain	WPC low-end mention	Quiet / watch local products
CONUS Atlantic / Gulf coast	No landfalling hurricane	NHC systems offshore (Fay, Polo, Nolo)	Quiet on the mainland

What this means for restoration teams

Sunday afternoon is a close-out and water day, not a chase day. Northeast shops should finish tree-and-roof tickets from the expired High Wind Warnings and stay ready for urban water calls if the Slight Risk trains on already-wet ground. North Texas and southern Oklahoma shops watch local warnings only. High Plains shops can stand down the morning hail Marginal.

Wind that already happened is siding, gutter, and tree-on-structure work. New water on a Slight Risk is wet drywall and a 24–48 hour mold clock. Photograph in daylight if it is safe, call the carrier, and start extraction the same night if water is inside.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. SPC has no severe thunderstorm area and no watch. Polo is Baja. Nolo is south of Hawaii. Fay is mid-Atlantic open water. Do not invent a named-CAT desk on the CONUS from those tracks.

Looking ahead

SPC Day 2 (Monday) also has no severe thunderstorm areas forecast. Severe thunderstorm probability remains low. WPC discussion language for Monday raises a Moderate excessive-rainfall risk over parts of the Southwest, Great Basin, and central and southern Rockies as Polo moisture is drawn inland — that is tomorrow’s flood overlay, not today’s. Watch the next Storm Tracker update rather than assuming Sunday’s quiet line holds after 12 UTC Monday.

Storm Updates: High Plains Hail Marginal, Nor’easter Wind Fade — Sunday, September 27, 2026 (Morning)

This is a live Sunday morning snapshot of U.S. local-storm activity as of Sunday, September 27, 2026. Overnight into this morning, the organized severe desk stayed quiet. No Storm Prediction Center tornado or severe thunderstorm watches are valid. The last issued convective watch remains Watch 674, already expired. The 1300 UTC Day 1 Convective Outlook, issued 0730 AM CDT and valid 271300Z–281200Z, holds a Marginal Risk of severe thunderstorms for portions of the central and northern High Plains. Summary language from Norman: isolated thunderstorms capable of large hail will be possible across portions of western Nebraska and the Black Hills of South Dakota. No tornado or damaging-wind probability areas are forecast. Restoration exposure this morning is leftover Mid-Atlantic and southern New England wind from the fading nor’easter, isolated High Plains hail later today, and a Weather Prediction Center Slight excessive-rainfall overlay on parts of southern New England.

Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

No convective watches are current. The SPC watch page states no watches are valid. Today’s storm-report window that opened at 1200 UTC Sunday shows no tornado, hail, or wind reports yet. The overnight board from the Saturday convective day is thin and local: quarter-size hail near Lake Lawtonka in Comanche County, Oklahoma, at 0033 UTC, plus trees down about seven miles west of Central High and roadway damage about six miles north of Hulen in the same county just before 0000 UTC. That is yesterday’s western Oklahoma Marginal verifying as isolated cells, not a watch overlay that carried into Sunday.

The 1300 UTC Day 1 outlook draws a 5 percent hail contour over about 48,893 square miles and roughly 328,899 people. Larger centers inside the contour include Rapid City, Spearfish, Rapid Valley, and Sturgis in South Dakota, and Scottsbluff, Nebraska. A residual moist axis with 60s F surface dewpoints still reaches from the southern Plains into Nebraska and South Dakota. Forcing stays weak through the day, which should keep coverage isolated. Evening coverage may increase as a subtle vorticity maximum and a modest low-level jet arrive. Large hail is the named hazard with the strongest storms. SPC also notes scattered thunderstorms over north and central Texas late this afternoon and isolated to widely scattered storms from northern Utah into central Wyoming, with localized gusty winds possible but not enough confidence for a low-probability severe highlight.

The Weather Prediction Center short-range discussion issued 422 AM EDT Sunday keeps a Slight Risk of excessive rainfall over parts of southern New England on Sunday into Monday morning. The same discussion holds a Moderate Risk for Monday over parts of the Southwest, Great Basin, and central and southern Rockies — that is tomorrow’s water desk, not this morning’s. A strong nor’easter still drifts near the New Jersey coastline. WPC language: widespread minor to moderate coastal flooding is expected for at least one more high-tide cycle Sunday morning after significant coastal flooding Saturday. Wind gusts of 40 to 50 mph remain possible Sunday morning from New Jersey to Long Island. NWS wind advisories were still live into noon EDT for New York City, Long Island, coastal and southeast Connecticut, the Hudson Valley, and the Berkshires. Gale Warnings remain on New England coastal waters. Dense fog was also in play early this morning over parts of south-central Nebraska and north-central Kansas until 11 AM CDT. A Flood Advisory covers pieces of Bourbon and Crawford Counties in southeastern Kansas into early afternoon.

Hotspot 1 — Western Nebraska and the Black Hills

This is the only categorical severe area on the Sunday Day 1 map. Isolated storms capable of large hail are the forecast, not a wind outbreak and not a tornado corridor. Heating on the western edge of the moist plume can build moderate buoyancy over western Nebraska even with some high cloud. Storm coverage stays limited until evening lift arrives.

Cities and counties to watch: Rapid City, Spearfish, Sturgis, and the Black Hills foothills in South Dakota; Scottsbluff and the Nebraska Panhandle. Restoration read: isolated hail dents and a few broken windows if a cell organizes, not a regional wind swath. Staff lightning and a tarp kit. Do not pre-position as if a Slight is coming.

Hotspot 2 — Mid-Atlantic and southern New England nor’easter fade

The live work here is leftover high wind, trees, wires, tidal water, and one more high-tide cycle — not an SPC convective watch. Saturday’s High Wind Warnings have largely rolled off into Wind Advisories and marine Gale Warnings. WPC is explicit that coastal and tidal flooding matter more than rainfall totals on the cold side of the low. Southern New England still sits under a Slight excessive-rainfall risk for localized urban and poor-drainage flooding as the rain slowly wanes.

Restoration read: this is the just-hit pile from Saturday night into Sunday morning. Check trees on service drops, wet basements, and coastal roads at high tide. Do not treat it as a new severe-thunderstorm outbreak. This is not a U.S. mainland hurricane landfall. Tropical Depression Fay is well west-southwest of the Azores. Hurricane Polo is a Baja California Sur forecast. Hurricane Nolo remains a Hawaii desk.

Hotspot 3 — North and central Texas, Utah–Wyoming scatter

SPC leaves these areas outside the Marginal contour. Scattered storms over north and central Texas late afternoon, plus isolated to widely scattered storms from northern Utah into central Wyoming, can still throw localized gusty winds. Coverage and magnitude were not enough for a 5 percent wind highlight on the 1300 UTC update. Treat local Severe Thunderstorm Warnings if they fire. Do not invent a watch.

Just hit

Sunday’s 1200 UTC storm-report window is empty as of this morning desk: no tornado, hail, or wind LSRs yet today. Overnight into early Sunday, the Saturday report day closed with isolated Comanche County, Oklahoma work — quarter hail northeast of Lake Lawtonka and trees plus roadway damage west of Central High and north of Hulen. That is the just-hit convective ticket. The larger just-hit desk is coastal wind and tidal water from New Jersey through southern New England after Saturday’s nor’easter blow.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
Western NE / Black Hills SD	Isolated large hail	SPC 1300 UTC Marginal	Afternoon into evening
NJ / NYC / Long Island / southern New England	Residual wind, tidal flood, urban rain	Wind advisories; WPC Slight rain	Fading through Sunday
Comanche County, OK	Trees, quarter hail	Saturday LSRs	Just hit overnight
North / central TX; northern UT–central WY	Localized gusty wind	General thunderstorms	Late day scatter
CONUS severe watches	None	No watches; last was 674	Quiet
SPC LSRs today (from 12Z Sun)	None yet	0 tornado / 0 hail / 0 wind	Quiet

What this means for restoration teams

Sunday morning is a quiet-pulse-plus-leftover desk. The convective piece is a small High Plains hail Marginal with no watch and an empty Sunday LSR board. Treat that as isolated cells later today, not a regional event. The live volume is already on the ground along the Mid-Atlantic and southern New England coast: trees, wires, and wet interiors from Saturday into this morning’s last high tide. Interior water still starts a 24–48 hour mold clock. Photograph in daylight if it is safe. Do not drive flooded coastal roads at high tide.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. SPC has one Marginal hail area and no Slight or higher. No convective watch is up. Today’s LSR board is empty. The nor’easter is a fading high-wind and coastal-flood event on the cold side of the low. That is the local-storm pattern this desk should staff.

Looking ahead

SPC Day 2 and Day 3 convective outlooks carry no severe thunderstorm areas. WPC lifts a Moderate excessive-rainfall risk Monday over parts of the Southwest, Great Basin, and central and southern Rockies, with a Slight over parts of the Upper Midwest Monday. Watch the afternoon Storm Tracker rather than assuming the High Plains Marginal is the last line of the week.

Storm Updates: Mid-Atlantic High Wind, Southern Plains Marginal — Saturday, September 26, 2026

This is a live Saturday afternoon snapshot of U.S. local-storm activity as of Saturday, September 26, 2026. The organized severe desk is a small Marginal over the southern Plains, not a national outbreak. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook, issued 0250 PM CDT and valid 262000Z–271200Z, holds a Marginal Risk of severe thunderstorms late this afternoon and evening from western Oklahoma into northwest Texas. Summary language from Norman: isolated hail and strong outflow winds may accompany thunderstorms across portions of the southern Plains late this afternoon into the early evening. The outlined Marginal covers about 32,889 square miles and roughly 748,515 people, with larger centers including Wichita Falls, Lawton, Enid, Yukon, and Altus. No convective watches are valid. Restoration exposure this afternoon is split: tree and power-line wind on the Mid-Atlantic and southern New England High Wind Warnings, isolated hail and outflow gusts on the Oklahoma–northwest Texas Marginal, and water on the Weather Prediction Center Slight excessive-rainfall areas over Iowa and the coastal Northeast.

Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

No tornado or severe thunderstorm watches are current. The SPC watch page states no watches are valid. The last issued convective watch on the board is Watch 674, already expired. No mesoscale discussions are in effect. The 20Z Day 1 update kept the forecast generally on track and made only a slight southward expansion of the 5 percent wind probability. As of 1945 UTC, a deepening cumulus field was noted from West Texas into southwestern Oklahoma, with isolated thunderstorm development ongoing over the higher terrain of southwest Texas. Temperatures had warmed into the upper 80s to mid 90s F, with temperature-dewpoint spreads approaching 30 F in parts of northwest Texas. Steep low-level lapse rates may support isolated strong or damaging outflow gusts, with an instance of large hail also possible farther north where deep-layer shear is marginally stronger. A lack of stronger synoptic-scale forcing, generally modest mid-level flow, and poor mid-level lapse rates are expected to limit overall intensity and coverage.

The Weather Prediction Center Day 1 Excessive Rainfall Outlook, updated 1556 UTC Saturday and valid 16Z Saturday through 12Z Sunday, holds a Slight Risk of excessive rainfall for parts of the coastal Northeast and Iowa. WPC notes a large nor’easter crawling off the Delaware and southern New Jersey coast, with a 986 mb center as of the 16Z discussion. Coastal and tidal flooding, aided by a full moon and the storm’s slow motion, are described as substantially more impactful than rainfall flooding. The Slight was expanded slightly to include urban northern New Jersey and urban central Connecticut. A higher-end Slight that had covered eastern Massachusetts, Rhode Island, and eastern Long Island was dropped with the 16Z update. All of the Northeast sits on the cold, northwest side of the storm, so instability for truly heavy convective rain is lacking. This remains a prolonged light-to-moderate rain event stacked on tides and high wind, not a warm-sector flash-flood outbreak.

Iowa’s Slight was left unchanged for central and southwestern Iowa. High-resolution guidance suggests showers and storms on the nose of a low-level jet this evening and tonight. Wet soils have lowered flash-flood guidance into the 1 to 1.5 inch per hour range. Instability is the limiter, struggling to exceed 500 J/kg. A Marginal Risk also remains over more sensitive parts of West Texas around the Davis Mountains and Stockton Plateau.

High Wind Warnings remain the live non-convective overlay on the Mid-Atlantic and southern New England coast. NWS Mount Holly continues a High Wind Warning until 6 AM EDT Sunday for the Delaware beaches and coastal New Jersey zones including Eastern Monmouth, Atlantic Coastal Cape May, Coastal Atlantic, and Coastal Ocean, with north winds 30 to 40 mph and gusts up to 60 mph. NWS Boston/Norton continues High Wind Warnings until 8 AM EDT Sunday for portions of eastern, northeastern, and southeastern Massachusetts and Rhode Island, with northeast winds 20 to 30 mph and gusts up to 50 to 60 mph depending on zone. Those products are trees and power lines, not SPC severe thunderstorm watches.

Hotspot 1 — Western Oklahoma into northwest Texas

This is the only categorical severe area on the Saturday Day 1 map. The 20Z outlook keeps isolated hail and strong outflow as the hazards late afternoon into early evening. Surface-based storms can still form where heating wins west of leftover morning cloud from southwest Oklahoma into Kansas. Cities inside the Marginal include Wichita Falls, Lawton, Enid, Yukon, and Altus. Isolated thunderstorms were already firing on the higher terrain of southwest Texas by mid-afternoon.

Restoration read: isolated wind and a possible hail stone, not a watch overlay. Staff lightning and a few downed limbs if a cell organizes near Lawton, Altus, or the Wichita Falls side of the Red River. Do not pre-position as if a Slight or Enhanced is coming. Photograph any hail or wind damage in daylight if it is safe.

Hotspot 2 — Jersey Shore, Delaware beaches, southern New England

The live work here is High Wind Warnings plus coastal and tidal flooding under a slow nor’easter, not an SPC convective watch. Mount Holly holds the warning through 6 AM Sunday on the Delaware beaches and the New Jersey coastal strip from Sandy Hook and Eastern Monmouth through Atlantic City, Long Beach Island, and Cape May. Boston/Norton holds through 8 AM Sunday from the North Shore and Boston through the South Coast, Cape Cod, the Islands, and Rhode Island. WPC’s Slight rainfall risk still covers parts of the coastal Northeast, including urban northern New Jersey and urban central Connecticut, but the 16Z discussion is explicit: coastal and tidal flooding matter more than the rain totals.

Restoration read: trees, wires, and wet basements on a long-duration coastal blow. Power outages are the expected ticket language in the NWS impact statements. Do not drive inundated coastal roads at high tide. This is not a hurricane landfall and not a derecho. Hurricane Nolo is a Hawaii desk. Hurricane Polo is a Baja California Sur forecast, not a U.S. East Coast landfall.

Hotspot 3 — Central and southwestern Iowa

WPC left the Slight Risk unchanged at 16Z for central and southwestern Iowa. Cell training along a northwest-southeast stationary front is still possible this evening and tonight on already wet soils. Earlier discussion language also kept eastern Nebraska and far northern Missouri in the broader rain corridor, with some 24-hour amounts able to reach or exceed 2 inches where storms train. Instability stays weak. Occasional mainly elevated thunderstorms remain possible from northeast Oklahoma northward to Iowa per the SPC Day 1 discussion, but that is not a categorical severe area.

Restoration read: water on poor drainage and low crossings tonight, not hail or a wind swath. Check Saturday night into Sunday morning for ponding. Turn around, don’t drown.

Just hit

SPC today’s storm reports for the 1200 UTC September 26 through 1159 UTC September 27 window show no tornado reports, no hail reports, and no wind reports as of this afternoon desk. The severe board is still empty for today’s convective day.

The work that is already a ticket is coastal wind and water on the Mid-Atlantic and southern New England side of the nor’easter, plus leftover runoff from the last several days on the southern High Plains. Those are NWS high-wind and flood products, not today’s SPC local storm reports. Do not reprint Friday’s New Mexico flash-flood warnings as Saturday LSRs.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this afternoon
Western OK / northwest TX	Isolated hail, outflow wind	SPC 2000 UTC Marginal	Live late afternoon / evening
DE beaches / NJ coast / southern New England	High wind, trees, tidal flood	NWS High Wind Warnings; WPC Slight rain	Warnings into Sunday morning
Central / southwestern Iowa	Training rain, isolated runoff	WPC Slight	Evening / overnight
West Texas mountains	Localized heavy rain	WPC Marginal	Isolated
CONUS severe watches	None	No watches; last was 674	Quiet
SPC LSRs today	None	0 tornado / 0 hail / 0 wind	Quiet

What this means for restoration teams

Saturday afternoon is a split desk. The convective piece is a small Marginal from western Oklahoma into northwest Texas with no watch and an empty LSR board. Treat that as isolated cells, not a regional wind event. The live volume sits on the Mid-Atlantic and southern New England High Wind Warnings: trees, wires, and wet basements under a slow nor’easter. Iowa is an overnight water check on already wet ground.

Interior water still starts a 24–48 hour mold clock. Photograph in daylight if it is safe. Do not drive flooded coastal roads at high tide or low crossings in Iowa tonight. Hurricane Nolo remains a Hawaii flood-and-wind desk south of the Big Island. Hurricane Polo is forecast for Baja California Sur, not the U.S. mainland. Tropical Storm Gonzalo and Tropical Depression Fay are well out in the eastern and central Atlantic. Do not mix those crew maps with the Jersey Shore wind pile or the Oklahoma Marginal.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. SPC has one Marginal area and no Slight or higher. No convective watch is up. No mesoscale discussion is up. Today’s LSR board is empty. The nor’easter is a high-wind and coastal-flood event on the cold side of the low, not a tropical cyclone making landfall on the East Coast. That is the local-storm pattern this desk should staff.

Looking ahead

The SPC Day 2 Convective Outlook, issued 1247 AM CDT Saturday and valid 271200Z–281200Z Sunday, carries no severe thunderstorm areas. Summary: severe thunderstorms are not expected Sunday. An upper low is expected to meander over the lower Hudson Valley while ridging prevails over the Plains. Isolated to widely scattered thunderstorms are possible from the Great Basin into the Plains, but overlapping buoyancy and shear look limited. Day 3 also has no severe thunderstorm areas. Sunday’s restoration check is leftover Mid-Atlantic wind damage and any Iowa runoff that verifies overnight, not a new severe outbreak.

September 26, 2026

Storm Updates: Mid-Atlantic High Wind, Southern Plains Marginal — Saturday, September 26, 2026 (Morning)

This is a live Saturday morning snapshot of U.S. local-storm activity as of Saturday, September 26, 2026. Overnight into this morning, the organized severe desk stayed quiet: no Storm Prediction Center convective watches are valid. The 1300 UTC Day 1 Convective Outlook draws a Marginal Risk of isolated hail and strong outflow winds for western Oklahoma into northwest Texas late this afternoon into early evening. The Weather Prediction Center Day 1 Excessive Rainfall Outlook holds Slight Risk pockets from southwest Iowa into northern Missouri and along the Mid-Atlantic and southern New England coast, with a broader Marginal overlay from the southern Plains into the central Plains.

The live work this morning is not a watch box. It is High Wind Warnings on the Mid-Atlantic and southern New England coast from a strengthening coastal low, leftover water in north-central Kansas where a flash-flood warning was replaced by a flood advisory, and a few overnight local storm reports. These are county-scale thunderstorms and coastal wind, not a U.S. mainland hurricane landfall. Restoration exposure today is wind-driven trees and service drops on the coast, isolated hail and outflow later on the southern Plains, and interior water where yesterday’s High Plains rain is still in the channel. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

SPC current watches: none. Most recently issued watch was 0674, already expired. The 0655 AM CDT Day 1 discussion (Smith/Bentley) is explicit: morning showers and thunderstorms over the southern High Plains should dissipate, with new storm development around 21–23 UTC (4–6 p.m. CDT). Isolated large hail and severe gusts are possible mainly 22z–02z. Elsewhere, SPC calls the severe environment quiescent.

WPC valid 12Z Saturday through 12Z Sunday: Slight Risk of rainfall exceeding flash-flood guidance from roughly southwest Iowa into northern Missouri, and a second Slight along the Mid-Atlantic and southern New England coast from the Delmarva through Cape Cod and adjacent waters. A Marginal Risk covers a large southern-to-central Plains corridor plus a coastal Mid-Atlantic/Northeast swath.

National Hurricane Center: Tropical Depression Fay and Tropical Storm Gonzalo are well out in the open Atlantic and are not a U.S. land threat this morning. Hurricane Nolo remains nearly stationary well south of the Big Island of Hawaii and is forecast to stay south of the islands; that is a Hawaii flood-and-wind desk, not a mainland landfall. Eastern Pacific Hurricanes Odalys and Polo are Mexico-waters storms, not CONUS landfalls.

Hotspot 1 — Mid-Atlantic and southern New England high wind

This is the live warning desk. National Weather Service Mount Holly holds a High Wind Warning until 6:00 a.m. EDT Sunday for Delaware beaches and coastal New Jersey counties including Eastern Monmouth, Atlantic Coastal Cape May, Coastal Atlantic, and Coastal Ocean. Language: north winds 30 to 40 mph with gusts up to 60 mph; trees and power lines; widespread outages possible. Boston/Norton holds High Wind Warnings until 8:00 a.m. EDT Sunday for eastern and southeastern Massachusetts and Rhode Island, with northeast gusts 50–60 mph on the exposed coast and 50 mph inland over Kent and Providence counties. WPC’s coastal Slight excessive-rainfall risk sits under the same system: heaviest totals preferred offshore, but localized heavy rain can still reach the Jersey Shore through southern New England.

Cities and counties to watch: Atlantic City, Long Beach Island, Ocean City, Rehoboth Beach, Sandy Hook; Boston, Quincy, Plymouth, New Bedford, Cape Cod, Nantucket, Martha’s Vineyard; Providence, Warwick, Newport, Westerly.

Restoration read: wind first. Stage tree crews, generators, and tarp kits before the next peak gust period tonight. Treat coastal ZIPs as possible interior-water jobs if the Slight rain overlay verifies on already-wet ground. Photograph roofs in remaining daylight only if it is safe.

Hotspot 2 — Western Oklahoma into northwest Texas (afternoon Marginal)

SPC’s only categorical severe area today. A High Plains upper trough and a smaller-scale jet over the Texas Panhandle into Oklahoma maintain a lee trough and dewpoints in the lower to mid 60s. Morning convection is expected to die. New storms 21–23 UTC from south-central Kansas through western Oklahoma and west/northwest Texas. Adequately strong deep-layer shear supports a few organized cells capable of isolated large hail and severe outflow, mainly 22z–02z. Lubbock’s hazardous-weather outlook already flags isolated afternoon and evening storms off the Caprock with gusts to 65 mph and hail to quarter size.

Restoration read: this is a late-day hail and wind ticket, not a morning watch. Do not pre-position as if a Slight or Enhanced is up. Staff local warnings if they fire after 4 p.m. CDT.

Hotspot 3 — Leftover High Plains water and central Plains flood overlay

NWS Hastings replaced a flash-flood warning with a Flood Advisory through 1:00 p.m. CDT for parts of Jewell, Mitchell, Osborne, and Smith Counties in north-central Kansas. That is yesterday’s rain still in the ditch, not a new MCS. WPC keeps a Slight excessive-rainfall risk over southwest Iowa into northern Missouri and a Marginal from Oklahoma and West Texas north across Kansas toward the eastern Dakotas. Friday afternoon’s New Mexico flood pulse is no longer the national Slight; treat Cibola and Santa Fe as aftermath unless a new warning posts.

Great Falls holds a High Wind Warning until noon MDT for Glacier, Toole, and Pondera High Plains zones — westerly 30–50 mph, gusts to 70. That is a plains wind event, not the SPC Marginal.

Just hit

Overnight and Friday evening local storm reports, all preliminary: landspout near Wilmore in Comanche County, Kansas; one-inch hail that cracked windshields at Tecolote and near Romeroville in San Miguel County, New Mexico; 59–61 mph measured gusts in Liberty and Pondera Counties, Montana. Earlier Friday into last night on the Texas side of the same High Plains corridor: 60 mph at Memphis in Hall County, an estimated 60 mph north of Study Butte, and a roof section blown onto a road in Terlingua, Brewster County. No tornado watch fired. No convective watch is live this morning.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
Coastal NJ / DE / southern New England	Damaging wind, trees, outages, localized heavy rain	High Wind Warning + WPC Slight (coast)	Live warnings through Sunday morning
Western OK / northwest TX / south-central KS	Isolated hail, severe outflow	SPC Marginal 22z–02z	Afternoon–evening development
SW Iowa / northern Missouri	Training rain, flash flood	WPC Slight	Today into tonight
North-central Kansas (Jewell–Smith)	Residual flooding	Flood Advisory to 1 p.m. CDT	Aftermath / still in channel
Northern MT High Plains	High wind gusts to 70 mph	High Wind Warning to noon MDT	Live, expires midday
Hawaii (Nolo)	Flood watch Big Island / Maui County	NHC hurricane well south of islands	Hawaii desk only
U.S. mainland tropical	No landfalling hurricane	Fay / Gonzalo open Atlantic	Quiet on the mainland coast

What this means for restoration teams

Coastal gusts of 50–60 mph are tree-on-structure, siding, gutter, and service-drop work. Stage before dark on the Jersey Shore and southern New England, not after the first outage ticket. The Oklahoma–Texas Marginal is a late-day hail and wind desk: a few cells, not a regional outbreak. Kansas flood-advisory counties are already wet — extraction and drying, not a new watch. Hawaii Nolo stays off the mainland board.

Property owners: photograph damage in daylight if it is safe, call the carrier, and start extraction the same night if water is inside. Turn around, don’t drown at low-water crossings in the WPC Slight counties.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. No convective watch is up. The work today, if it comes, will be scattered: a coastal wind swath through a New Jersey or Massachusetts county, a late-day hail core in western Oklahoma, leftover water in a Kansas creek. That is the local-storm pattern this desk should staff.

Looking ahead

Coastal High Wind Warnings run through early Sunday. The southern Plains Marginal is a same-day afternoon problem, not an overnight watch. SPC Day 2 language on the hazard matrix is No Severe for Sunday. Watch the next Storm Tracker update rather than assuming this morning’s High Wind Warning is the last line of the weekend.

Storm Updates: New Mexico Flood Slight, Quiet Severe Pulse — Friday, September 25, 2026

This is a live Friday afternoon snapshot of U.S. local-storm activity as of Friday, September 25, 2026. The organized desk is still water on the southern High Plains, not a national wind outbreak. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook, issued 0251 PM CDT and valid 252000Z–261200Z, carries no severe thunderstorm areas. Summary language from Norman: organized severe thunderstorms are not expected today. The 20Z update made no changes. Isolated thunderstorms were noted across western Oklahoma around 1945 UTC, but cloud cover continues to limit heating. The Weather Prediction Center Day 1 Excessive Rainfall Outlook still holds a Slight Risk of excessive rainfall across portions of the southern High Plains, with moisture lifting northeast toward the central Kansas–Nebraska border and the northern Nebraska–Iowa border tonight.

Restoration exposure this afternoon is water: leftover runoff from last night’s New Mexico–west Texas MCS, live flash-flood warnings on the Albuquerque desk, and isolated heavy cells if storms redevelop on already wet ground. Wind and hail remain a low-confidence scatter, not a watch overlay. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

No tornado or severe thunderstorm watches are current. The SPC watch page, updated 1804 UTC Friday, states no watches are valid. The last issued convective watch on the board is Watch 674, already expired. No mesoscale discussions are in effect as of 2010 UTC Friday. Yesterday evening’s 0100 UTC Day 1 outlook had carried a Marginal Risk over parts of the Texas Panhandle; that window closed overnight. Today’s packages dropped categorical severe probabilities entirely.

Water products are the live overlay. NWS Albuquerque issued a flash-flood warning at 135 PM MDT Friday for east-central Cibola County until 430 PM MDT, covering Laguna Pueblo, New Laguna, Mesita, Acoma Pueblo, Paraje, Seama, and Acomita, including Interstate 40 between mile markers 106 and 121. Radar indicated up to 1 inch already down with another half inch possible. A second Albuquerque warning at 220 PM MDT covers west-central Santa Fe County until 515 PM MDT. Midland/Odessa continues a Flood Watch through this evening for portions of southeast New Mexico — Central Lea, Eddy County Plains, Guadalupe Mountains of Eddy County, Northern Lea — and southwest Texas including the Davis and Guadalupe Mountains, Marfa Plateau, Presidio Valley, and the Van Horn corridor. Albuquerque also continues a Flood Watch until midnight MDT for east-central and southeast New Mexico, including Curry, Roosevelt, Chaves, Quay, De Baca, eastern Lincoln, and the south-central mountains.

Hotspot 1 — Cibola and Santa Fe Counties, New Mexico

This is the live afternoon ticket. Albuquerque’s Cibola warning is radar-indicated heavy rain on already sensitive ground, with life-threatening flash-flood language on creeks, urban areas, and I-40. The Santa Fe County warning is the same pattern a county east: up to an inch already, more possible through mid-afternoon. These are not the overnight Eddy–Chaves–Otero warnings from the morning desk. Those expired. This is a new pulse on the west-central and north-central New Mexico side of the same moisture plume.

Restoration read: water first. Do not treat I-40 between Grants and Albuquerque as a clean haul if the Cibola warning is still live. Photograph high-water marks after the product expires. Extraction and drying on structures that took this afternoon’s pulse start the same 24–48 hour mold clock as last night’s Pecos Valley work. Turn around, don’t drown on pueblo and canyon crossings.

Hotspot 2 — Southeast New Mexico into West Texas (Flood Watch)

WPC keeps the Slight Risk from southeastern New Mexico to the southern Panhandle and south into parts of West Texas where 3-hour flash-flood guidance is under an inch. Midland’s Flood Watch through this evening names Artesia, Carlsbad, Hobbs, Lovington, Alpine, Marfa, Fort Davis, Van Horn, and Presidio. Guidance had morning storms diminishing as the shortwave lifted northeast, then allowed localized 1–2 inch amounts later in the day on wet soils. Gaines County, Texas, took a morning flash-flood warning from Midland at 734 AM CDT until 1030 AM CDT for Seminole and Seagraves; that product is expired and belongs in the just-hit column.

Restoration read: leftover water from Thursday night plus any new cells on the watch. Stage pumps where last night’s warnings sat — Eddy, Chaves, Otero, El Paso, Hudspeth — and keep an eye on Lea County and the Davis Mountains if afternoon storms fire. This is still not a wind event.

Hotspot 3 — Western Oklahoma scatter and the central Plains rain axis

SPC’s 20Z discussion notes isolated thunderstorm development across western Oklahoma as of 1945 UTC, with cloud cover still tempering surface heating. A stronger gust or two remains possible where a cell finds a pocket of better heating, but the overall severe risk is limited. That is why there is still no categorical severe area and no watch. Farther north, WPC notes that shortwave energy and tropical-origin moisture lifting out of the Southwest can support efficient rainfall tonight near the central Kansas–Nebraska border northeast toward the northern Nebraska–Iowa border, with some guidance showing more than 2 inches. Instability stays weak. Treat that as isolated runoff, not a Moderate flood upgrade.

Restoration read: western Oklahoma is lightning and a possible isolated gust. Kansas–Nebraska–Iowa is a Saturday-morning check on poor-drainage and low crossings if the overnight rain verifies, not a Friday afternoon extract pile.

Just hit

SPC today’s storm reports for the 1200 UTC September 25 through 1159 UTC September 26 window show no tornado reports, no hail reports, and no wind reports as of this afternoon desk. That is a Quiet Pulse on the severe board.

The work that already happened is water. Overnight flash-flood warnings from Midland, Albuquerque, and El Paso/Santa Teresa covered northwestern Eddy County, southwestern Chaves County, and central Otero County in New Mexico, plus east-central El Paso and west-central Hudspeth Counties in Texas, where 2 to 3 inches had already fallen before dawn. Those products expired this morning. Midland’s Gaines County warning this morning for Seminole and Seagraves also expired. Survey and extraction replace that overlay. Thursday’s 60 mph wind report at Memphis in Hall County, Texas, remains yesterday’s High Plains Marginal, not a new Friday LSR.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this afternoon
Cibola / Santa Fe Counties, NM	Flash flood, I-40 runoff	NWS Albuquerque FFWs	Live until 430 / 515 PM MDT
SE NM / West Texas	Flash flood, leftover runoff	WPC Slight; Midland / ABQ Flood Watches	Watch through evening / midnight
Western OK cells	Isolated gust, lightning	SPC 2000 UTC: no categorical area	Scatter only
KS–NE–IA rain axis	Heavy rain tonight, isolated runoff	WPC discussion, no Moderate	Overnight check
CONUS severe watches	None	No watches; last was 674	Quiet
SPC LSRs today	None	0 tornado / 0 hail / 0 wind	Quiet

What this means for restoration teams

Friday afternoon is a Quiet Pulse on the severe side and a water desk in New Mexico. The live work is Cibola and Santa Fe Counties while those warnings are up, plus extraction on last night’s Eddy–Chaves–Otero–El Paso–Hudspeth pile. Interior water starts a 24–48 hour mold clock. Photograph in daylight if it is safe. Do not drive flooded crossings in the pueblos, the Sacramento Mountains, or the Pecos Valley.

Western Oklahoma and West Texas may still fire isolated strong cells before sunset. Staff that as local lightning and a possible isolated gust, not a regional wind swath. The Kansas–Nebraska rain axis is a Saturday morning check. Hurricane Nolo remains a Hawaii County flood-and-wind desk. Fay and Gonzalo in the Atlantic and Polo and Odalys in the eastern Pacific are not U.S. mainland landfalls this afternoon. Do not mix those crew maps with the New Mexico water pile.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. SPC has no Day 1 severe area. No convective watch is up. No mesoscale discussion is up. Today’s LSR board is empty. Thursday’s Moderate flood risk over southeast New Mexico remains stepped down to a Slight. The work this afternoon is leftover water plus two live Albuquerque flash-flood warnings. That is the local-storm pattern this desk should staff.

Looking ahead

The SPC Day 2 Convective Outlook, issued 1226 PM CDT Friday and valid 261200Z–271200Z Saturday, carries a Marginal Risk of severe thunderstorms late Saturday afternoon and evening from northwest Texas into central Kansas. Summary: isolated hail and strong outflow winds may accompany thunderstorms across portions of the central and southern Plains Saturday. Day 3 Sunday has no severe thunderstorm areas. WPC Day 2 steps the Northeast up to a Slight excessive-rainfall risk Saturday as a nor’easter deepens east of New Jersey, with 1–3 inches possible from the northern Mid-Atlantic into southern New England. That is Saturday’s overlay, not tonight’s New Mexico ticket.

September 25, 2026

Storm Updates: Southern High Plains Flood Slight, Quiet Severe Day — Friday, September 25, 2026 (Morning)

This is a live Friday morning snapshot of local storm-type events across the United States as of the morning of Friday, September 25, 2026. The organized desk is still water on the southern High Plains, not a national wind outbreak. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook, valid 251300Z–261200Z, carries no severe thunderstorm areas. Summary language from Norman: organized severe thunderstorms are not expected today. The Weather Prediction Center 12Z Day 1 Excessive Rainfall Outlook, valid 12Z Friday through 12Z Saturday, holds a Slight Risk of excessive rainfall across portions of the southern High Plains — southeast New Mexico into the Texas Panhandle and parts of West Texas.

These are county- and ZIP-scale thunderstorms and leftover runoff, not a U.S. mainland hurricane landfall. Restoration exposure this morning is water already in low crossings and buildings from last night’s New Mexico–west Texas MCS, plus isolated heavy rain if cells redevelop this afternoon. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

No tornado or severe thunderstorm watches are current. The SPC watch page, updated 1300 UTC Friday, states no watches are valid. The last issued convective watch on the board is Watch 674, already expired. Yesterday evening’s 0100 UTC Day 1 outlook had carried a Marginal Risk over parts of the Texas Panhandle; that window closed overnight. Today’s 1300 UTC package dropped categorical severe probabilities entirely.

Overnight flash-flood warnings from Midland/Odessa, Albuquerque, and El Paso/Santa Teresa covered northwestern Eddy County, southwestern Chaves County, and central Otero County in New Mexico, plus southeastern El Paso County and parts of Hudspeth County in western Texas. Those products were valid into the predawn hours — Eddy and Chaves until 530 AM MDT, Otero until 730 AM MDT, El Paso extensions into 330–445 AM MDT. By this morning desk they have expired. That is the just-hit pile, not a live warning overlay.

Hotspot 1 — Southeast New Mexico into the Texas Panhandle and West Texas

This is today’s flood ticket, trimmed from Thursday’s Moderate. WPC’s 410 AM EDT Friday discussion keeps a Slight Risk from southeastern New Mexico to the southern Panhandle and extends it south into parts of West Texas, where 3-hour flash-flood guidance is under an inch. Overnight activity over eastern New Mexico and the Texas Panhandle can still produce additional flooding concerns into mid to late morning. Guidance then has storms diminishing as the shortwave and deeper moisture lift northeast. Afternoon cells over West Texas can still dump 1–2 inches locally on already wet ground.

SPC’s Day 1 discussion notes a convectively modified disturbance over eastern New Mexico lifting toward the central High Plains, mid- and high-level clouds over western Oklahoma, and only a low-probability severe gust if a stronger storm develops late this afternoon in western Oklahoma. Southern New Mexico, in the wake of the early-day MCS, may see a couple of stronger cells with some hail risk, but confidence in a severe-caliber threat is low. That is why there is no categorical severe area this morning.

Cities and counties to watch: Artesia, Hope, Lakewood, and Brantley Lake in Eddy County; Dunken and Elk in southwestern Chaves; Sacramento, Mayhill, and Weed in Otero; Tornillo, Hueco Tanks, and rural east-central El Paso and Hudspeth Counties. Streams named in overnight warning text include the Rio Penasco, Bluewater Creek, and Agua Chiquita Creek.

Restoration read: water first. Extraction and drying on structures that took overnight runoff. Low-water crossings and rural roads in the Sacramento Mountains and Pecos Valley stay a drive-around, not a drive-through. Stage pumps where last night’s warnings sat. Do not treat this as a wind event.

Hotspot 2 — Western Oklahoma scatter

SPC leaves the door cracked for a stronger storm or two late this afternoon over western Oklahoma under modest mid-level lapse rates and up to about 1500 J/kg MLCAPE, with a low-probability severe gust. Cloud cover from the departing MCS and tropical-origin moisture aloft will limit heating. This is not a watch candidate at 1300 UTC. Treat it as isolated outflow and lightning, not a Plains outbreak.

Hotspot 3 — Hurricane Nolo, Big Island of Hawaii

The National Hurricane Center and Central Pacific Hurricane Center are issuing advisories on Hurricane Nolo. As of the 200 AM HST Friday advisory, Nolo was near 15.8°N 155.6°W, moving north-northeast at 5 mph, with maximum sustained winds of 85 mph and a minimum pressure of 980 mb. Headline language: catastrophic and life-threatening flash flooding possible on the Big Island of Hawaii into the weekend. Local NWS Honolulu products own the island warning suite. This is a Hawaii County flood-and-wind desk, not a CONUS landfall. Fay and Gonzalo in the Atlantic and Odalys and Polo in the eastern Pacific are not U.S. mainland land threats this morning.

Just hit

SPC today’s storm reports for the 1200 UTC September 24 through 1159 UTC September 25 window show no tornado reports and no hail reports as of this desk. One preliminary wind report: 60 mph at Memphis in Hall County, Texas, at 1758 UTC Thursday, relayed by NWS Lubbock. That is yesterday afternoon’s High Plains Marginal, not a new overnight severe pile.

The overnight work that did verify is water. NWS Midland issued a flash-flood warning for northwestern Eddy County until 530 AM MDT covering Artesia, Hope, Seven Rivers, Brantley Lake, Dayton, Lakewood, and Atoka. Albuquerque warned southwestern Chaves County until 530 AM MDT for Dunken and Elk, with considerable damage-threat language on the Rio Penasco and Bluewater Creek. El Paso/Santa Teresa warned central Otero County until 730 AM MDT for Sacramento, Mayhill, Weed, and several canyons, and separately warned pieces of El Paso and Hudspeth Counties where 1 to 3 inches had already fallen. Those warnings are expired this morning. Survey and extraction replace the warning overlay.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
SE NM / TX Panhandle / West Texas	Flash flood, leftover runoff, isolated heavy rain	WPC Slight excessive rainfall	Overnight FFWs expired; Slight still live
Western OK / southern NM cells	Isolated gust or hail, low confidence	SPC 1300 UTC: no categorical area	Afternoon scatter only
Hall County, TX (Memphis)	60 mph wind Thursday afternoon	Yesterday Marginal LSR	Just-hit / closed
Big Island, Hawaii	Flash flood, tropical wind	Hurricane Nolo, 85 mph	Live Hawaii desk
CONUS severe watches	None	No watches valid; last was 674	Quiet

What this means for restoration teams

Friday is a Quiet Pulse on the severe side and a water desk on the southern High Plains. Overnight flash flooding in Eddy, Chaves, Otero, El Paso, and Hudspeth Counties is the work that already happened. Interior water starts a 24–48 hour mold clock. Photograph in daylight if it is safe. Do not drive flooded crossings in the Sacramento Mountains or the Pecos Valley.

Western Oklahoma and southern New Mexico may still fire isolated strong cells this afternoon. Staff that as local lightning and a possible isolated gust or hail stone, not a regional wind swath. Hawaii County is a separate tropical-flood ticket under Nolo. Do not mix that crew map with the New Mexico overnight pile.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. SPC has no Day 1 severe area. No convective watch is up. Thursday’s Moderate flood risk over southeast New Mexico has been stepped down to a Slight. The work this morning is leftover water and a trimmed rainfall overlay. That is the local-storm pattern this desk should staff.

Looking ahead

The SPC 0600 UTC Day 2 Convective Outlook, valid 261200Z–271200Z Saturday, carries a Marginal Risk of severe thunderstorms for portions of the central and southern Plains. Summary: isolated hail and damaging winds may accompany a few strong to severe thunderstorms Saturday from parts of Kansas into western Texas and Oklahoma, including the Wichita-to-Lubbock corridor. Watch the afternoon Storm Tracker rather than treating Friday’s quiet severe map as the weekend map.

September 25, 2026

Storm Updates: Southeast New Mexico Flood Moderate, High Plains Marginal — Thursday, September 24, 2026

This is a live Thursday afternoon snapshot of U.S. local-storm activity as of Thursday, September 24, 2026. The organized desk is water, not a national wind outbreak. The Weather Prediction Center 16Z Day 1 Excessive Rainfall Outlook upgrade holds a Moderate Risk of excessive rainfall across parts of southeast New Mexico. The Storm Prediction Center 1630 UTC Day 1 Convective Outlook holds a Marginal Risk of severe thunderstorms across portions of the eastern Texas Panhandle, western Oklahoma, and western Kansas. No convective watches are in effect as of the 2107 UTC SPC watch page.

These are county-scale thunderstorms and flash-flood cells on saturated soils, not a mainland hurricane landfall. Restoration exposure this afternoon and tonight is interior water and mud where New Mexico cells train, plus isolated wind, hail, and tree work if a High Plains downburst verifies. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

SPC’s 1630 UTC Day 1 outlook, issued 1114 AM CDT Thursday, September 24, 2026, and valid 1630Z Thursday through 1200Z Friday, places a Marginal Risk over about 42,181 square miles and roughly 370,000 people. Named population centers inside the contour include Dodge City, Kansas; Altus, Oklahoma; Pampa, Texas; Woodward, Oklahoma; and Elk City, Oklahoma. The official summary: a couple of marginally severe thunderstorms are possible late this afternoon into the early evening across parts of the southern High Plains. A 2000 UTC outlook update discussed on secondary feeds left the contour unchanged and pointed to Mesoscale Discussion 2327; by 1801 UTC the SPC mesoscale page showed no discussions in effect, with 2326 the most recent archived number.

WPC’s Day 1 excessive-rainfall discussion issued 417 PM EDT Thursday, September 24, 2026, upgraded the existing Slight Risk to a Moderate Risk for portions of southeast New Mexico after coordination with NWS Albuquerque and El Paso. The language cites slow-moving thunderstorms, saturated soils from multiple prior Moderate ERO days, and HREF neighborhood probabilities over 70 percent for both 3 inches of rain and 10-year ARI exceedance over parts of Lincoln, Chaves, and Otero counties. Surrounding Slight and Marginal flood-risk language remains over parts of the Southwest into the southern and central Plains. WPC Mesoscale Precipitation Discussion 1375, issued 238 PM EDT Thursday and valid 1838Z Thursday through 0003Z Friday, flags the Pecos River Valley: flash flooding likely, with 2 to 4 inches possible where cells backbuild near the Sacramento Mountains.

No tornado or severe thunderstorm watches are current. The last issued convective watch on the SPC board is Watch 674, already expired. SPC today’s storm reports (1200 UTC September 24 through 1159 UTC September 25) show one preliminary wind report as of this desk: 60 mph at Memphis in Hall County, Texas, at 1758 UTC, relayed by NWS Lubbock. No hail or tornado reports have posted on that same page yet.

Hotspot 1 — Southeast New Mexico: Lincoln, Chaves, Otero

This is the live flood upgrade. WPC and WFO coordination put the Moderate Risk on the eastern slope of the Sacramento Mountains and the upper Pecos drainage, where soils already sit at very high NASA SPoRT moisture percentiles and flash-flood guidance is low. Cities and counties to watch: Ruidoso and the Lincoln County high country, Roswell and Chaves County, Alamogordo and Otero County, plus adjacent terrain toward the Texas line covered by MPD 1375.

Restoration read: water first. Treat any ZIP that takes a 1- to 2-inch-per-hour core as an extraction job tonight, not a tomorrow morning survey. Photograph only if it is safe. Low-water crossings and arroyos fail before the living room does. Turn around, don’t drown.

Hotspot 2 — Eastern Texas Panhandle, western Oklahoma, western Kansas

This is the SPC Marginal contour. Outlook language from Mosier and Chalmers at 1114 AM CDT Thursday: mid-to-upper 60s dewpoints east of a mid-level moisture plume, afternoon temperatures in the mid to upper 80s, MLCAPE 1500 to 2000 J/kg, weak shear, disorganized storm mode, a few water-loaded downbursts, and a couple of weak supercells possible into Kansas where a weak vorticity maximum moves through. Isolated hail or damaging gusts are the ceiling in the official text. Dodge City, Pampa, Amarillo’s eastern approaches, Altus, Elk City, and Woodward sit inside or on the edge of that language.

Restoration read: isolated wind and hail tickets, not a line. Stage one tarp crew and one extractor, not a CAT convoy. The 60 mph Memphis, Texas, report is the only official LSR on today’s SPC page as of this writing — treat it as a local pulse, not proof the whole contour verified.

Hotspot 3 — Hawaii County under Tropical Storm Nolo; East Coast coastal low is not a named landfall

The National Hurricane Center and Central Pacific Hurricane Center are issuing advisories on Tropical Storm Nolo. As of the Thursday afternoon NHC/CPHC board, Nolo was south of the Big Island with maximum sustained winds near 70 mph, a Tropical Storm Warning in effect for Hawaii County, and forecast language that it could reach hurricane strength later Thursday. That is U.S. land exposure on the Big Island. It is not a continental U.S. landfall.

Tropical Storm Fay is in the central Atlantic, hundreds of miles west-southwest of the Azores, and is not a U.S. land threat on current advisories. Hurricane Polo is off southwestern Mexico. Hurricane Odalys is well west-southwest of Baja. WPC short-range discussion also flags a developing East Coast coastal low for coastal flooding, rip currents, wind gusts, and heavy rain into the weekend. That feature is not a named hurricane making U.S. landfall. Do not staff the Mid-Atlantic as if Fay or Polo were coming ashore.

Just hit

Yesterday’s SPC report page (1200 UTC September 23 through 1159 UTC September 24) is already a ticket list, not today’s new watch: quarter-size hail at New England in Hettinger County, North Dakota, at 2307 UTC; a tree down at Van Wert in Polk County, Georgia, at 2000 UTC; a 58 mph gust 4 SE of Frederick in Tillman County, Oklahoma, at 2158 UTC. Overnight into this morning, NWS Dodge City had a Flash Flood Warning covering parts of Grant, Hamilton, Kearny, Morton, and Stanton counties in southwestern Kansas until 500 AM CDT Thursday after 2 to 3 inches of rain. That Kansas water is yesterday-into-dawn work still on the books.

The Thursday morning Storm Updates already logged the New Mexico–Plains flood slight and Dakotas hail pulse. This afternoon post is the upgrade desk: WPC Moderate on southeast New Mexico, SPC Marginal still on the High Plains, watches still zero.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
SE New Mexico (Lincoln / Chaves / Otero)	Flash flood, training 2–4 in cores	WPC Moderate + MPD 1375	Live flood desk
Eastern TX Panhandle / western OK / western KS	Isolated damaging gusts, isolated hail	SPC Marginal	No watch; late-day cells
SW Kansas overnight counties	Already-fallen 2–3 in rain	Expired FF.W overnight	Aftermath / still wet
Hawaii County	TS wind, surf, heavy rain	Tropical Storm Warning (Nolo)	Live tropical warning
East Coast coastal low	Coastal flood, rip, gusty wind	WPC short-range language	Not a named landfall
CONUS watches	None	No valid SPC watch	Quiet watch board

What this means for restoration teams

Southeast New Mexico is a water night. Saturated soils plus another 2 to 4 inches in a training core is wet drywall, crawlspaces, and a 24-to-48-hour mold clock. High Plains Marginal cells, if they verify, are roof, siding, and isolated tree-on-structure work — staff them as single-ZIP pulses. Hawaii County under Nolo is a separate tropical desk: wind-driven rain, surf, and outages on the Big Island, not a Gulf or Atlantic landfall. Do not mix those three crews in one dispatch board.

For teams near Roswell, Ruidoso, or Alamogordo: stage extractors and pumps before dark, not after the first flash-flood warning. For teams near Pampa, Altus, or Dodge City: one severe-warned cell is the ticket, not the whole outlook contour. Property owners should photograph damage in remaining daylight only if it is safe, call the carrier, and start extraction the same night if water is inside.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Fay is mid-ocean. Polo is off Mexico. Odalys is well offshore in the eastern Pacific. Nolo is a Hawaii County warning, which is real U.S. land exposure, but it is not the CONUS headline. The work tonight, if it comes, will be scattered: a flooded arroyo in Lincoln or Chaves County, a downburst roof in the Texas Panhandle or western Oklahoma, leftover Kansas water from last night. That is the local-storm pattern this desk should staff.

Looking ahead

The SPC 1730 UTC Day 2 Convective Outlook issued 1228 PM CDT Thursday, September 24, 2026, valid 1200Z Friday through 1200Z Saturday, carries no severe thunderstorm areas. Summary: severe thunderstorms are not expected Friday. WPC Day 2 excessive rainfall, updated Thursday, holds a Marginal Risk from New Mexico into the Plains and over southeast New England. Day 3 convective language on the SPC homepage still shows a later Marginal window. Watch the next Storm Tracker update rather than assuming today’s Moderate flood contour is the last water line of the week.

Storm Updates: New Mexico–Plains Flood Slight, Dakotas Hail Pulse — Thursday, September 24, 2026 (Morning)

This is a live Thursday morning snapshot of local storm-type events across the United States as of the morning of Thursday, September 24, 2026. Overnight into this morning, the organized severe corridor from Wednesday’s western Dakotas Marginal Risk did verify on the Local Storm Report board — a brief tornado west of Hettinger and baseball-size hail near South Heart, North Dakota. Convective watches are not currently valid. The Storm Prediction Center 0600 UTC Day 1 Convective Outlook, valid 241200Z–251200Z, carries no categorical severe thunderstorm areas. Isolated stronger storms with hail or gusty winds remain possible late this afternoon and early evening from southeast Arizona and southern New Mexico into the Texas Panhandle and western Oklahoma and Kansas.

The water desk is still the national headline, not wind. Weather Prediction Center short-range language this morning keeps a Slight Risk of excessive rainfall over portions of New Mexico into the south-central Plains, with a broader Marginal Risk from the Four Corners into the central Plains as leftover tropical moisture and embedded shortwaves keep training cells possible on already wet ground. These are county- and ZIP-scale thunderstorms and flash-flood pulses, not a U.S. mainland hurricane landfall. Restoration exposure today is leftover water in New Mexico and the southern High Plains, isolated hail and wind on the Dakotas just-hit pile, and a Hawaii watch for Tropical Storm Nolo well south of the Big Island.

Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

No Storm Prediction Center convective watches are currently valid. The most recently issued watch on the SPC board is Severe Thunderstorm Watch 674, a Sunday-night eastern Colorado and western Kansas product that expired days ago. Yesterday’s western Dakotas and southern Appalachians Marginal Risk is off the Day 1 map. The 0600 UTC discussion from Guyer and Thornton is plain: organized severe thunderstorms are unlikely today and tonight. The same discussion still flags pockets of moderate destabilization into peak heating across southeast Arizona, southern New Mexico, and the southern High Plains.

The SPC overview hazard matrix later this morning lists Thursday as a Marginal severe day. Treat that as the later-cycle read against the published 0600 UTC text of “no severe thunderstorm areas forecast.” Either way, this is not a watch morning. Isolated hail or a damaging gust is the ceiling unless a new outlook or mesoscale discussion draws a tighter box this afternoon.

On the flood side, Wednesday’s Weather Prediction Center Day 1 Moderate Risk over the Texas and Oklahoma Panhandles and central and eastern New Mexico has rolled off the valid window. Thursday language from WPC’s short-range public discussion is a step down: Slight Risk of excessive rainfall over portions of New Mexico into portions of the south-central Plains, Marginal Risk across much of the Four Corners into the central Plains. Soils are still saturated. Rates, not coverage, are the problem if a cell trains.

Hotspot 1 — New Mexico into the Texas and Oklahoma Panhandles and western Kansas

This remains the water desk. Overnight, National Weather Service Dodge City issued a Flash Flood Warning for northwestern Grant, southeastern Hamilton, western Kearny, northeastern Morton, and eastern Stanton Counties in southwestern Kansas until 5:00 a.m. CDT. Radar-indicated totals of 2 to 3 inches were already on the ground at issuance, with another 1 to 2 inches possible. That warning is off the clock this morning. It is the signature of the same moisture plume that spent midweek over New Mexico.

WPC still expects scattered showers and thunderstorms Thursday as large-scale forcing weakens but instability and embedded shortwave energy remain. Portions of New Mexico and Texas stay sensitive because of the multi-day rain. Localized 1-inch-per-hour rates on burn scars, arroyos, urban streets, and low water crossings are the first failures. A separate, lower-coverage pulse is possible in southeast Arizona under the same southwesterly mid-level flow.

Restoration read: extraction and drying on buildings that took water Tuesday and Wednesday, plus a new poor-drainage ticket if a cell parks on a ZIP that already failed. Do not treat the whole Moderate-Risk footprint from yesterday as still live. Staff the county that still has a warning, not the outline from Wednesday afternoon.

Hotspot 2 — Western North Dakota just-hit pile

Wednesday afternoon’s western Dakotas Marginal Risk produced the overnight LSR pile. Preliminary Storm Prediction Center reports for the 1200 UTC September 23 through 1159 UTC September 24 window include:

A brief tornado around 2236 UTC about 3 miles south-southwest of Bucyrus in Adams County, North Dakota, based on social-media video and radar, west of Hettinger. NWS Bismarck logged the location as approximate.
Quarter-size hail (1.00 inch) at New England, Hettinger County, at 2307 UTC.
Half-dollar hail (1.25 inches) about 3 miles southeast of Belfield, Stark County, at 2340 UTC.
Baseball-size hail (2.75 inches) about 2 miles southwest of South Heart, Stark County, at 2345 UTC.

Those are official preliminary LSRs, not social rumor. Hail that size breaks windows, dents siding, and wrecks HVAC fins. The tornado report is a one-minute touchdown, not a long-track event. Restoration work there is already a survey-and-tarp job, not a new watch.

Hotspot 3 — Southern High Plains scatter plus leftover wind reports

SPC’s Day 1 discussion leaves the door open for a few stronger, locally severe storms late this afternoon and early evening from southeast Arizona and southern New Mexico into the Texas Panhandle and western Oklahoma and Kansas. That is isolated hail and gusty outflow, not a Slight Risk corridor. Yesterday’s board also carries a 58 mph thunderstorm gust 4 miles southeast of Frederick in Tillman County, Oklahoma, at 2158 UTC, and a tree down in Van Wert, Polk County, Georgia, at 2000 UTC. Those are scatter, not a line.

Farther east, an amplifying coastal low off the Mid-Atlantic and New England is a marine and coastal-flood story, not a convective watch. WPC flags coastal flooding, rip currents, and heavy rain along the East Coast into the weekend. That is a different desk from the New Mexico flood pulse.

Tropical — Nolo south of Hawaii, not a mainland landfall

Central Pacific Hurricane Center is issuing advisories on Tropical Storm Nolo. As of 2:00 a.m. HST Thursday, Nolo was about 285 miles south of South Point, Hawaii, and about 460 miles south-southeast of Honolulu, stationary, with maximum sustained winds near 50 mph and a minimum pressure of 999 mb. Official language: Nolo is forecast to intensify into a hurricane late today and could become a major hurricane by the weekend. That is a Hawaii County and offshore-waters problem, not a Gulf or East Coast landfall. Hurricane Polo and Hurricane Odalys remain in the eastern Pacific off Mexico. Tropical Storm Fay is in the open Atlantic well west-southwest of the Azores and is not a U.S. land threat.

Just hit

Wednesday’s live desk was still water over central and eastern New Mexico, with SPC trimmed to a western Dakotas Marginal. That Dakotas box verified overnight on hail and a brief tornado. The New Mexico Moderate flood risk has stepped down to Slight into the south-central Plains. Southwestern Kansas took a late-night flash-flood warning that expired at 5:00 a.m. CDT. No new convective watch fired overnight. Watch 674 is not today’s product.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
NM into TX/OK Panhandles and western KS	Flash flood, training heavy rain	WPC Slight excessive rainfall	Live flood overlay; KS FFW expired 5 a.m. CDT
SE AZ / southern NM / southern High Plains	Isolated hail, gusty wind, heavy rain	SPC 0600 UTC: no categorical area; isolated stronger storms possible	Afternoon–evening scatter
Western ND (Hettinger / Stark)	Hail damage, brief tornado	Yesterday Marginal; LSRs in	Just-hit / survey
Four Corners to central Plains	Isolated heavy rain	WPC Marginal excessive rainfall	Diurnal cells
East Coast marine / New England coast	Coastal flood, wind, heavy rain	WPC / OPC coastal low	Not a convective watch
Hawaii — Nolo	Tropical storm to hurricane risk south of the islands	CPHC TS Nolo, 50 mph	Watch Hawaii products, not mainland
Atlantic / Gulf vs. U.S. mainland	No landfalling hurricane	Quiet on the mainland coast	Quiet

What this means for restoration teams

New Mexico and the southern High Plains are still a water week. Saturated ground plus another Slight Risk means the next training cell is a wet-drywall and crawlspace ticket, not a surprise. Photograph and extract what already flooded before you chase a new ZIP. Southwestern Kansas counties that sat under last night’s warning should be treated as just-hit poor-drainage work until local offices drop the flood language.

Western North Dakota is a hail desk. Baseball stone southwest of South Heart is broken glass and bruised roofs. The Adams County tornado report is a narrow path. Staff it as a local damage survey. Do not read “tornado” on an LSR board as a regional event.

If the later SPC cycle firms a Marginal box over the southern High Plains, the work is still isolated hail and outflow, not a watch. Stage tarps only where a warning is live. Hawaii shops should follow Central Pacific Hurricane Center products on Nolo, not this CONUS flood pulse.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Polo and Odalys are eastern Pacific storms off Mexico. Fay is mid-Atlantic open water. Nolo is a Central Pacific storm still south of the Big Island. The CONUS work this morning is leftover flood water, a North Dakota hail pile, and a quiet watch board.

Looking ahead

SPC Day 2, valid Friday, currently carries no severe thunderstorm areas. WPC still sees the moisture axis shifting east Friday into the south-central Plains and Midwest with another heavy-rain overlay possible. SPC Day 3 language returns a Marginal Risk later in the weekend as an upper trough works the central United States. Watch the afternoon Storm Tracker rather than assuming Thursday’s quiet watch board is the last line of the week.

Storm Updates: New Mexico Flood Moderate, Western Dakotas Marginal — Wednesday, September 23, 2026

This is a live Wednesday afternoon snapshot of U.S. local-storm activity as of Wednesday, September 23, 2026. The organized desk is still water, not wind. The Weather Prediction Center Day 1 Excessive Rainfall Outlook holds a Moderate Risk across portions of central and eastern New Mexico. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook (issued 2:58 p.m. CDT; Halbert/Lyons; valid 232000Z–241200Z) trims the severe overlay to a Marginal Risk across parts of the western Dakotas only. The southern Appalachians Marginal from the morning 1300 UTC package is off the 2000 UTC map. No convective watches are currently valid. No mesoscale discussions are in effect.

These are county- and ZIP-scale flood and isolated hail/wind pulses, not a U.S. mainland hurricane landfall. Restoration exposure this afternoon into tonight is water first in New Mexico and far west Texas (training storms, burn-scar runoff, arroyos), leftover wet soils from Ohio through the southern Appalachians, and isolated damaging gusts or marginally severe to locally 2-inch hail if the western Dakotas cells organize. Separately, Tropical Storm Nolo now carries a Hurricane Watch for Hawaii County — not a CONUS landfall, and not the Restoration Intel CAT desk. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

SPC’s 2000 UTC update says the western Dakotas forecast remains largely on track. Isolated damaging wind gusts and severe hail are possible late this afternoon where moisture pooling has put upper-50s to low-60s °F dewpoints under clearing skies. Moderate deep-layer shear and modest buoyancy (500–1,000 J/kg MLCAPE; 30–40 kt 0–6 km shear) can support organized storms and transient supercells. A CIG 1 contour was added for isolated 2-inch hail with any stronger supercell. Population centers named in the Marginal contour: Dickinson, North Dakota; Belle Fourche, South Dakota; Sidney, Montana. Tornado probabilities remain zero. No watches as of the SPC watches page update at 21:00:23 UTC Wednesday, September 23, 2026. Most recent watch on the board: 0674.

Southern Appalachians: the 2000 UTC outlook removed the 5% wind probabilities. Widespread low stratus, modest buoyancy, and a mostly cluster/multicell mode keep the severe potential low even as lightning continues in eastern Tennessee along the inverted trough.

WPC Day 1 Excessive Rainfall Outlook (updated 0832 UTC Wednesday, September 23, 2026; Chenard; valid 12Z Wed–12Z Thu) still owns the national headline: Moderate Risk across portions of central and eastern New Mexico. Scattered to numerous flash floods expected; locally significant and life-threatening impacts remain possible on sensitive terrain, urban drainage, and burn scars. Widespread 1–2 inches generally expected, localized 2–4 inch swaths on top of pre-12Z rain. HREF/REFS neighborhood probabilities of more than 3 inches run 40–70% on the eastern half of the Moderate area. Slight Risk into southeast Arizona and a slice of far west Texas. Separate flood desks: Slight over portions of eastern Kentucky, eastern Tennessee, and far western North Carolina; Marginal from Ohio into West Virginia and western Virginia/North Carolina; Marginal over south Florida.

Live NWS flood products this morning into midday included a flash-flood warning from NWS Albuquerque for the South Fork burn scar in south-central Lincoln County (issued 9:08 a.m. MDT, through 12:15 p.m. MDT; 0.5–1.25 inches already down; Brady, Bear, Perk, Cedar Creek, Eagle Creek, and Rio Ruidoso drainages). Flood watches remain in effect through this evening / late tonight across much of central and eastern New Mexico and south-central New Mexico including the Tularosa Basin / Alamogordo / Doña Ana corridor (NWS Albuquerque and NWS El Paso/Santa Teresa).

Hotspot 1 — Central and eastern New Mexico / far west Texas

Still the organized desk. Mid-level shortwave lifting north-northeast across New Mexico, robust upper divergence, easterly upslope, and training cells in deep southerly flow. Cloud cover is the limiter; the eastern edge of the rain shield is where heating and CAPE can still fire the heavier cores. Burn scars and arroyos fail first. The South Fork burn scar warning this morning is the restoration ticket type: debris flow of rock, mud, and vegetation into reservoirs, bridges, culverts, and the Rio Ruidoso downstream of Ruidoso Downs.

Restoration read: water first. Stage pumps and air movers before the next training band. Start extraction the same night if water is inside. Do not drive flooded arroyos. Turn around, don’t drown.

Hotspot 2 — Western Dakotas / Black Hills

The only remaining SPC Marginal as of 2000 UTC. Lee trough and moisture plume from the High Plains; widely scattered storms near the Black Hills and the Dickinson–Belle Fourche–Sidney corridor late afternoon into early evening. Isolated damaging gusts and severe hail, with a conditional isolated 2-inch hail note if a transient supercell holds together. No tornado contour. No watch.

Restoration read: isolated wind and hail, not a regional outbreak. Stage only if you already work western North Dakota, western South Dakota, or far eastern Montana. Do not pull crews off the New Mexico water desk for this.

Hotspot 3 — Eastern Tennessee / southern Appalachians flood leftover + Tropical Storm Nolo (Hawaii County)

SPC took the Marginal off this corridor at 2000 UTC. The flood overlay is still live: WPC Slight over eastern Kentucky, eastern Tennessee, and far western North Carolina; WPC Marginal from Ohio into West Virginia and western Virginia/North Carolina. Wet soils from the last several days keep flash-flood guidance low even with reduced precipitable water. Lightning and modest CAPE along the inverted trough can still produce locally heavy cells. That is a water job, not a tarp outbreak.

Separately, Central Pacific Hurricane Center / NHC Advisory 13 at 11:00 a.m. HST Wednesday, September 23, 2026: Tropical Storm Nolo, 14.5°N 155.3°W, about 310 miles south of South Point, Hawaii, 40 mph sustained, moving west-northwest at 6 mph. A Hurricane Watch is in effect for Hawaii County. Forecast: approach the Big Island Friday and Saturday; possible hurricane Thursday and possible major hurricane by the weekend. Rainfall: 15–20 inches on the Big Island with maxima near 35 inches; 5–10 inches on Maui with maxima near 20 inches. Storm surge 1–3 feet possible in Hawaii County. This is a Hawaii land threat on Friday–Saturday, not a CONUS landfall today. Polo and Odalys remain eastern Pacific systems off Mexico / well west of Baja.

Restoration read: Appalachians = leftover plus second-chance street and creek water. Hawaii County = watch the NHC package Friday; do not invent a mainland hurricane from Nolo.

Just hit

SPC local storm reports for the current 23/1200 UTC–24/1159 UTC window, as of this afternoon check: no tornado, no hail, no wind reports received yet. Do not invent LSR points for today.

The prior 22/1200 UTC–23/1159 UTC window still holds the last 24-hour ticket pile: quarter-size hail near Sterlington, Louisiana; Suncrest, Utah; and south of Colorado Springs. Wind damage across Lauderdale, Cherokee, DeKalb, St. Clair, and Shelby counties in Alabama (trees, lines, a pole on a vehicle, roof and tree damage in Montevallo). Odessa, Texas, lines and outbuilding/carport damage. Measured 59 mph near Rawlins, Wyoming. Measured 68 and 74 mph southwest of Sundown in Cochran County, Texas. Overnight into this morning the flood desk already logged El Paso County, central Virginia (Amelia / Powhatan), and a receding western North Carolina pulse around Lake Lure / Bat Cave, plus today’s South Fork burn-scar warning in Lincoln County, New Mexico.

Pulse table

Region	Main threats	SPC / WPC / NWS level	Status this afternoon
Central / eastern NM and far west TX	Flash flood, training storms, burn-scar runoff	WPC Moderate + NWS flood watches / FFW	Live flood desk through Thu 12Z
Western Dakotas / Black Hills	Isolated hail / damaging gusts; conditional 2″ hail	SPC Marginal	Late afternoon–early evening
Southeast AZ	Localized flash flood	WPC Slight	Today
Eastern KY / eastern TN / far western NC	Flash flood on wet soils	WPC Slight; SPC Marginal removed at 2000Z	Afternoon–evening water
OH into WV / western VA–NC	Localized flash flood	WPC Marginal	Today
South Florida	Urban flash flood	WPC Marginal	Local
Hawaii County	TS Nolo; hurricane conditions possible late Friday	NHC Hurricane Watch	Watch now; land threat Fri–Sat
U.S. mainland tropics	No CONUS landfalling named cyclone	NHC	Quiet for CONUS land

What this means for restoration teams

New Mexico remains the water job if the Moderate risk verifies — extraction, drying, and a 24–48 hour mold clock, plus debris-flow cleanup on burn scars. Far west Texas is the eastward leak of the same plume. The Dakotas Marginal is isolated hail and wind for shops that already cover Dickinson, the Black Hills, and Sidney. The Appalachians are leftover water, not a new severe overlay. Hawaii County is a Friday–Saturday NHC problem, not today’s CONUS roll. Stage the New Mexico pumps now. Start extraction the same night if water is inside. Turn around, don’t drown.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. There is no Slight or Enhanced convective risk on the 2000 UTC Day 1 map. There are no valid convective watches. Do not write Nolo as a Gulf or Atlantic landfall; it is a Central Pacific storm with a Hurricane Watch for Hawaii County and a forecast approach to the Big Island on Friday and Saturday. Hurricane Polo (eastern Pacific, off southwest Mexico) and Hurricane Odalys (well west of Baja) are not CONUS land threats today. Today’s CONUS work, if it verifies, is New Mexico flash flood plus isolated western Dakotas hail/wind.

Looking ahead

SPC Day 2 Convective Outlook for Thursday (issued 12:44 a.m. CDT Wednesday, September 23, 2026; Squitieri; valid 241200Z–251200Z) shows no severe thunderstorm areas. Showers and scattered storms can still run from the Interior West into the central Plains behind the same Southwest impulse, but shear and buoyancy do not overlap enough for probabilities. That does not cancel tonight’s New Mexico flood problem or this afternoon’s Dakotas Marginal. Watch the next Storm Tracker update rather than assuming the Moderate rainfall risk is the last line of the week. Nolo’s Hawaii County watch is the tropical item to re-check Thursday afternoon.

September 23, 2026

Storm Updates: New Mexico Flood Moderate, Dakotas–Appalachians Marginal — Wednesday, September 23, 2026 (Morning)

This is a live Wednesday morning snapshot of local storm-type events across the United States as of the morning of Wednesday, September 23, 2026. Overnight into this morning, the flood desk ran ahead of the severe desk: National Weather Service flash-flood warnings for El Paso County, Texas; Amelia, Cumberland, and Powhatan counties in central Virginia; and a receding western North Carolina pulse around Lake Lure / Bat Cave / Chimney Rock. Those overnight warnings are treated as expired or expiring into this morning. Today’s desks: Storm Prediction Center Marginal Risk for parts of the western Dakotas and the southern Appalachians; Weather Prediction Center Moderate Risk of excessive rainfall across portions of central and eastern New Mexico. No convective watches are currently valid.

These are county- and ZIP-scale thunderstorms and flood pulses, not a U.S. mainland hurricane landfall. There is no named tropical cyclone threatening U.S. land in the current National Hurricane Center picture. Restoration exposure today into tonight is water first in New Mexico and far west Texas, leftover street and creek flooding in central Virginia and the southern Appalachians, and isolated damaging gusts this afternoon if the two Marginal corridors heat. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

SPC’s 1300 UTC Day 1 Convective Outlook (issued 7:26 a.m. CDT Wednesday, September 23, 2026; Smith/Mead; valid 231300Z–241200Z) places a Marginal Risk over parts of the western Dakotas and the southern Appalachians. Summary: isolated severe thunderstorms are possible this afternoon across those two corridors. Western Dakotas: mid-level trough moving out of Wyoming/Montana, lee trough, moisture plume off the High Plains, around 1,000 J/kg MLCAPE, isolated marginally severe hail or gusts through early evening. Southern Appalachians: mid-level vorticity maximum sliding southeast from the lower Ohio Valley; dewpoints in the 60s °F; 250–750 J/kg MLCAPE if heating wins against low cloud; strong to locally damaging gusts with the stronger cells. Hail probabilities were removed after the 12 UTC Nashville sounding showed poor 700–500 mb lapse rates (4.8 °C/km).

No convective watches were currently valid as of the SPC watches page update at 09:44:06 UTC Wednesday, September 23, 2026. Most recent watch on the board: 0674. Check spc.noaa.gov/products/watch before you stage.

WPC’s Day 1 Excessive Rainfall Outlook (updated 0832 UTC Wednesday, September 23, 2026; Chenard; valid 12Z Wed–12Z Thu) holds a Moderate Risk across portions of central and eastern New Mexico. Scattered to numerous flash floods are expected; locally significant and life-threatening impacts remain possible on sensitive terrain, urban drainage, and burn scars. A widespread 1–2 inches is generally expected, with localized 2–4 inch swaths likely on top of rain that already fell before 12Z. The Slight risk extends into southeast Arizona and a slice of far west Texas if storms propagate east. Separate flood desks: Slight over portions of eastern Kentucky, eastern Tennessee, and far western North Carolina; Marginal from Ohio into West Virginia and western Virginia/North Carolina; Marginal over south Florida.

Hotspot 1 — Central and eastern New Mexico / far west Texas

Today’s Moderate flood desk and the national headline. A well-defined mid-level shortwave lifts north-northeast across New Mexico with robust upper divergence and the chance of a weak surface low. Cloud cover is the limiter; daytime heating on the eastern edge of the rain shield plus easterly upslope should still support training cells in deep southerly flow. HREF/REFS neighborhood probabilities of more than 3 inches run 40–70% across the eastern half of the Moderate area. Overnight El Paso County already took radar-indicated 0.5–1.5 inch bursts and flash-flood warnings that expired before dawn.

Restoration read: water first. Stage pumps and air movers before the afternoon/evening cores organize. Burn-scar runoff and arroyos fail first. Start extraction the same night if water is inside. Turn around, don’t drown — most flood deaths are in vehicles.

Hotspot 2 — Southern Appalachians / eastern Tennessee

Dual desk: SPC Marginal for isolated damaging gusts, WPC Slight for flash flood on wet ground from eastern Kentucky through eastern Tennessee into far western North Carolina. Extensive low cloud this morning is the uncertainty. If breaks allow 250–750 J/kg MLCAPE, multicells along the inverted trough can put down strong gusts around peak heating. HREF/REFS neighborhood flash-flood-guidance exceedance peaks over eastern Tennessee (above 40% in spots). Overnight, NWS Greenville-Spartanburg held a flash-flood warning into 5:45 a.m. EDT for southeastern Buncombe, northeastern Henderson, southwestern McDowell, northwestern Polk, and northwestern Rutherford counties — 2.5–4 inches already down, waters receding by 3:05 a.m. EDT, Rocky Broad near Bat Cave falling through 6.58 feet.

Restoration read: leftover water plus a second-chance afternoon pulse. Do not treat receding creeks as closed. Stage extractors in eastern Tennessee and western North Carolina; tree and tarp crews only if the gusty cells actually fire.

Hotspot 3 — Western Dakotas

New SPC Marginal added on the 1300 UTC outlook. Mid-level trough crossing Wyoming/Montana reaches the western Dakotas late afternoon and deamplifies toward the Red River Valley by Thursday morning. Lee trough holds a moisture plume north from the central High Plains. Widely scattered storms near the Black Hills and lee trough this afternoon; isolated marginally severe hail or gusts through early evening. No major population centers sit inside the 5% hail contour.

Restoration read: isolated wind and hail, not a regional outbreak. Stage only if you already work the Black Hills / western Dakota corridor. Do not pull crews off the New Mexico water desk for this.

Just hit

Overnight flood, not overnight severe. NWS El Paso/Santa Teresa issued flash-flood warnings for northwestern and central El Paso County into the small hours (radar 0.5–1.5 inches, additional 0.5–1 inch possible; warnings through 3:15 a.m. MDT). Otero Mesa / northwest of Dell City had 2.5–3 inches radar-estimated earlier in the night with rural-road flooding held off Dell City by retention dams. NWS Wakefield: up to 4 inches since 11 p.m. in northwestern Amelia County and up to 5.5 inches since 10 p.m. in western Powhatan County; warnings through 4:00–5:30 a.m. EDT. Western North Carolina pulse receding after 2.5–4 inches.

SPC local storm reports for the 22/1200Z–23/1159Z window carried no tornado and no hail. Wind reports from late Tuesday afternoon remain on the board for Lauderdale County, Alabama (Lexington / Rogersville): power lines down, a brush fire, and a power pole/lines on a vehicle — already noted on yesterday’s afternoon Tygart Media desk. Do not invent additional LSR points.

What this means for restoration teams

New Mexico and far west Texas remain water jobs if the Moderate risk verifies — extraction, drying, and a 24–48 hour mold clock. Central Virginia and western North Carolina are aftermath from last night plus a second-chance flood axis this afternoon in eastern Tennessee. The Dakotas Marginal is isolated. Do not treat receding overnight warnings as a closed book; soils are primed. Stage before the New Mexico afternoon cores. Start extraction the same night if water is inside. Turn around, don’t drown.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. There are no tropical cyclones in the Atlantic basin at this hour. Hurricane Polo (Category 4, off southwest Mexico) and Hurricane Odalys (eastern Pacific, well west of Baja) are not CONUS land threats today. Tropical Depression Fifteen-E is a Central Pacific system near Hawaii, not a mainland U.S. landfall. Today’s work, if it verifies, is scattered: New Mexico flash flood, leftover Mid-Atlantic and Appalachian water, isolated Dakotas hail/wind, isolated southern Appalachian gusts.

Looking ahead

SPC Day 2 (Thursday) and Day 3 currently show no severe thunderstorm areas. That does not cancel today’s New Mexico flood problem or this afternoon’s two Marginal corridors. Day 4–8 language is only a possible localized Plains/Mid-Mississippi threat next Monday–Wednesday with weak shear — too unclear for probabilities. Watch the next Storm Tracker update rather than assuming the Moderate rainfall risk is the last line of the week.
