Storm Updates: Southwest Flood Moderate, New Mexico–West Texas Marginal — Tuesday, September 29, 2026

Tuesday afternoon desk. Water still owns the Southwest. A Marginal severe corridor is open from southeast Arizona across southern and eastern New Mexico into west Texas. Not an NWS warning. This is a live Tuesday afternoon snapshot of U.S. local-storm activity as of Tuesday, September 29, 2026. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook, issued 2:45 PM CDT, holds a Marginal Risk of severe thunderstorms from southern Arizona across southern and eastern New Mexico into west Texas. Isolated severe gusts and possibly a tornado or two remain the official language for this afternoon into tonight. No Severe Thunderstorm Watch or Tornado Watch is valid. Mesoscale Discussion 2333, issued 3:06 PM CDT for south-central into southeastern New Mexico, flags a sparse isolated gust or brief tornado and says a watch is unlikely.

The Weather Prediction Center still carries a Moderate Risk of excessive rainfall on portions of the Southwest and Four Corners after a late-Monday special Day 1 update trimmed the outline over western and northern Arizona into southern Utah. Restoration exposure this afternoon is interior water on already-saturated soils, wash and burn-scar flooding, trees and service drops on isolated severe gusts, and a narrow tornado swath if a cell organizes over southeastern New Mexico or west Texas. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

No convective watches are in effect as of the SPC watch page update at 21:04 UTC on Tuesday, September 29, 2026. The last issued watch number on that page is 0674 and it is not valid now. Today’s official Local Storm Report board covering 12Z Tuesday through 12Z Wednesday shows no tornado, hail, or wind reports as of this desk.

The 20Z update left severe probabilities unchanged. SPC expects thunderstorm coverage to increase this afternoon and evening as the remnant core of Polo moves northeast into the southern High Plains, likely in a complex or linear mode. Locally greater potential sits over southeastern New Mexico into West Texas, where less cloud cover allowed stronger heating through mid-afternoon. Population centers inside the Day 1 Marginal include El Paso, Tucson, Lubbock, Amarillo, and Midland.

National Hurricane Center Tropical Storm Polo Advisory 37, 2:00 PM MST Tuesday, September 29, 2026: the center was near 29.0°N, 109.7°W, about 275 miles southwest of El Paso, moving northeast at 21 mph with 65 mph maximum sustained winds and 992 mb pressure. Coastal watches and warnings for Mexico have been discontinued. Interests in northwestern Mexico, southern New Mexico, and far western Texas should keep watching the remnant. Polo is not a U.S. mainland hurricane landfall. NHC notes a Wind Advisory is in effect for portions of southern New Mexico and far western Texas for gusty remnant winds late today and tonight.

Hotspot 1 — Four Corners / Southwest flood pulse

This is still the water desk. WPC language supports a Moderate Risk of 1-to-6-hour rainfall exceeding flash-flood guidance over parts of the Southwest. The late-Monday 2200 UTC special update cut back Moderate coverage over western and northern Arizona into southern Utah after convection there stayed more scattered and instability stayed limited. Intense rates were then focused along a compact warm-conveyor axis over far southeastern California, the Arizona–Nevada border, and southwest Utah, plus a smaller pocket over southeast Arizona and southwest New Mexico downstream of Polo. Outside those pockets much of the rain over Arizona and New Mexico had been stratiform. Wet soils, burn scars, slot canyons, and south- and west-facing slopes along the Mogollon Rim and the San Juans still favor flooding even if the Moderate category is on the low end of that contour.

Cities and counties to watch: Kingman, Bullhead City, Laughlin, Colorado City, Hildale, Flagstaff and Mogollon Rim drainages, Lordsburg country and the Sacramento Mountains in New Mexico, and flashy drainages in southern Utah. Overnight Flash Flood Warnings on that corridor — Hildale and Short Creek, Colorado City and northern Mohave, the Laughlin–Kingman–Bullhead line, and pieces of San Bernardino and Clark counties — are yesterday-into-this-morning water, not a new afternoon watch.

Restoration read: extraction and drying first. Treat burn-scar and wash flooding as a same-night water job if rain is still falling on the same ZIP. Photograph only if it is safe. Do not drive flooded washes.

Hotspot 2 — Southeastern New Mexico into West Texas

This is the afternoon severe window inside the SPC Marginal. MD 2333 covers south-central into southeastern New Mexico, valid 2006–2130 UTC Tuesday. A small QLCS segment was intensifying on KHDX and MRMS as it approached a destabilizing airmass with surface temperatures in the 70s F, dewpoints in the 60s F, and more than 500 J/kg MLCAPE. Effective bulk shear over 40 kt, much of it in the lowest 3 km, leaves room for embedded mesovortices. Official MD language: an isolated severe gust or a brief tornado is possible through the remainder of the afternoon; the threat should stay sparse; watch issuance probability 5 percent. Most probable peak gust in that discussion is up to 60 mph; most probable peak tornado intensity is listed as up to 90 mph if one occurs.

Farther east, west Texas is the part of the Marginal that had more heating. Storm mode should trend complex or linear as Polo’s remnant and the low-level jet interact after 00Z. A brief tornado and strong gusts can ride any organized, persistent structure. That is still isolated, not a Slight Risk.

Restoration read: wind and water on the same ticket. Stage tarps and extractors for the South Plains and Permian Basin before late afternoon. A brief tornado, if one occurs, is a narrow swath — staff it as a local damage survey, not a regional event.

Hotspot 3 — Southeast Arizona and the Tucson–Phoenix moisture axis

Southern Arizona stays inside the same Day 1 Marginal. Mid-to-upper-60s dewpoints were analyzed from the international border into the Phoenix vicinity this morning, with long hodographs and 30 to 40 kt of low- and mid-level southwesterly flow. Widespread showers and thunderstorms continue under limited heating and weak tropical lapse rates. Weak or transient supercells and later convective bands can still produce strong gusts. This is not the higher-end part of the corridor compared with southeastern New Mexico and West Texas this afternoon, but Tucson sits inside the official risk area.

Restoration read: water first, wind second. Urban street flooding and isolated tree damage are the likely tickets, not a metro-wide wind event.

Just hit

Today’s 12Z-cycle LSR board is empty. The last 24 hours that already look like tickets sit on Monday’s 12Z-to-12Z page: 77 mph near Kenel and 71 mph near Pollock in Campbell County, South Dakota; 1.00-inch hail and a 60 mph gust 10 miles north of Belle Fourche in Butte County, South Dakota; power lines down near New Kingman-Butler in Mohave County, Arizona. Overnight Flash Flood Warnings on the Arizona–Utah–Nevada border country and a separate Fargo–Moorhead warning with up to two inches already down are water aftermath, not this afternoon’s new severe reports.

Tropical Storm Rachel remains offshore of southwestern Mexico and is not a U.S. land threat this afternoon. Hurricane Nolo is a Central Pacific / Hawaii desk. Neither is this Storm Tracker’s mainland corridor.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this afternoon
Four Corners / SW AZ–UT–NM	Flash flood, burn-scar and wash flooding	WPC Moderate excessive rainfall	Live flood pulse; Moderate trimmed on the northwest edge
SE New Mexico / West Texas	Isolated severe gust, brief tornado possible, heavy rain	SPC Marginal + MD 2333	Afternoon–tonight window; watch unlikely
Southeast Arizona / Tucson corridor	Strong gusts, heavy rain	SPC Marginal	Ongoing showers; limited heating
Eastern Dakotas / NW Minnesota	Training heavy rain	WPC Slight / Marginal ERO (prior discussion)	Fargo–Moorhead just-hit water
Western/central Dakotas (Monday)	Severe gusts, small hail	Expired Marginal + LSRs	Aftermath
U.S. mainland coast vs. tropics	No landfalling hurricane	Polo a TS inland over Sonora	Quiet on the mainland coast

What this means for restoration teams

The Southwest Moderate Risk is wet drywall, silt near washes, and a 24–48 hour mold clock on buildings that took water overnight. Southeastern New Mexico and west Texas are a wind-first desk if the QLCS or a discrete cell organizes, with water on the same ZIPs if cells train. Monday night’s Campbell County gusts are already a roof-and-siding ticket. Mohave County lines-down is already a tree-and-drop ticket.

For teams near the SPC Marginal: stage before late afternoon local, not after the first warning. Property owners should 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 remains the flood rule on every wash in the Moderate Risk.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Polo is a Mexico inland tropical storm whose remnant moisture and shear are already inside the Southwest and southern High Plains forecast. MD 2333 is explicit that the New Mexico severe threat should stay sparse and that a watch is unlikely. The work today, if it comes, will be scattered: a flooded wash in Mohave or Washington County, a wind swath through a southeastern New Mexico or west Texas county, leftover urban water in Fargo. That is the local-storm pattern this desk should staff.

Looking ahead

Wednesday’s SPC Day 2 Convective Outlook already draws a Slight Risk of severe thunderstorms across parts of the southern Plains, with damaging wind, hail, and perhaps a tornado or two from west-central Texas into southwest Oklahoma as an upper low and dryline organize. Isolated severe gusts and hail may also occur from western and central Kansas into far southern Nebraska. Thursday stays Marginal over parts of the southern Plains. Watch the next Storm Tracker update rather than assuming today’s Marginal is the last line of the week.

September 29, 2026

Storm Updates: Southwest Flood Moderate, Dakotas Marginal — Monday, September 28, 2026

Monday afternoon desk. Water still owns the Southwest. A small Marginal is now on the northern Plains. Not an NWS warning.

This is a live Monday afternoon snapshot of U.S. local-storm activity as of Monday, September 28, 2026. The morning desk opened with a blank severe map. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook, issued 0258 PM CDT, now carries a Marginal Risk of severe thunderstorms across parts of western and northern South Dakota and vicinity. No convective watches are valid. The last issued watch remains number 0674.

The Weather Prediction Center still holds a Moderate Risk of excessive rainfall over portions of the Southwest and Four Corners. The 16Z update expanded that Moderate southwest down the Colorado River to include the California–Arizona–Nevada tripoint. Restoration exposure this afternoon is water first on already wet Southwest ground, then isolated hail and gusty wind on the Dakotas Marginal, plus a short radar-indicated severe thunderstorm warning that fired over San Bernardino County, California. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

SPC summary language at 0258 PM CDT: isolated strong to severe thunderstorms may occur this afternoon and evening across parts of western and northern South Dakota and vicinity. The 20Z update notes stronger surface heating and less cloud cover near northwestern South Dakota, with temperatures into the low and mid 70s F downstream of developing convection near the Wyoming–South Dakota border. Storms were expected to form near the Black Hills around 20–22Z and spread east-northeast along a weak surface front. Stronger cells may produce isolated hail and gusty winds before becoming elevated across northern South Dakota and southern North Dakota later tonight.

Mesoscale Discussion 2330, issued 0240 PM CDT and valid through 2145 UTC, covers the western South Dakota vicinity. Concerning: severe potential, watch unlikely. Watch-issuance probability is 5 percent. SPC language: isolated strong to severe storms may produce sporadic hail through evening. Most probable peak hail size up to 1.25 inches. Most probable peak wind gust up to 60 mph. That is a local pulse, not a watch day.

WPC Day 1 excessive rainfall, updated 1537 UTC Monday and valid 16Z Monday through 12Z Tuesday, remains the national water headline. A Moderate Risk covers portions of the Southwest. The 16Z update expanded the Moderate to the CA/AZ/NV tripoint after coordination with NWS Las Vegas. Marginal and Slight areas were expanded north along the Nevada–Utah border. A separate Slight Risk remains over parts of North Dakota and northwestern Minnesota from training showers on the low-level jet. WPC notes much of the ongoing Arizona rain has been stratiform, but soils are already wet and the terrain is flashy.

National Hurricane Center as of the 2:00 PM MST Monday Polo advisory: Hurricane Polo is still a major hurricane near 25.0°N, 113.0°W, moving northeast at 12 mph, 115 mph maximum sustained winds, 963 mb. Life-threatening winds and flash flooding are beginning over portions of Baja California Sur. That is a Mexico land desk plus a U.S. flood-moisture feed. It is not a California or Arizona hurricane landfall. Hurricane Nolo remains a Central Pacific / Papahanaumokuakea desk. Tropical Storm Rachel is paralleling the southwest Mexico coast. Atlantic Tropical Depression Fay and Tropical Storm Hanna are not a CONUS land-threat desk this afternoon.

Hotspot 1 — Southwest and Four Corners flood Moderate

This is still today’s organized desk. Predecessor moisture from Polo and remnants of Odalys continues to lift north ahead of a mid-level shortwave moving from the California Valleys toward the lower Colorado River Valley. WPC guidance still supports a widespread 1 to 3 inches across the Four Corners region on soils already near saturation. South- and west-facing slopes along the Mogollon Rim and the San Juans remain favored. Burn scars, slot canyons, and rocky fans fail first.

Counties and terrain to watch this afternoon: Mogollon Rim and higher terrain in Arizona; western and southwestern New Mexico including burn-scar drainages near Lordsburg; the San Juan Mountains and adjacent southwest Colorado; southern Nevada valleys; and the newly expanded Moderate near the CA/AZ/NV tripoint and the lower Colorado River. WPC also flagged slow-moving lines along the Nevada–Utah border.

Restoration read: water first. Stage pumps, extractors, and sandbags on known flood ZIPs and burn-scar alluvial fans. Photograph crawlspaces and finished basements as soon as it is safe. Do not treat this as a wind event unless a local warning says otherwise.

Hotspot 2 — Western and northern South Dakota Marginal

This is the only categorical severe area on the current Day 1 map. SPC expects storms to form near the Black Hills and move east-northeast along a weak surface trough and front. MD 2330 keeps a watch off the table. Isolated quarter-to-golf-ball hail and 60 mph gusts are the staffed threats, not a derecho and not a tornado outbreak. Aberdeen and Rapid City county warning areas own the pulse. Northern South Dakota into southern North Dakota trends more elevated after dark.

Restoration read: isolated hail and tree work if a cell verifies. Do not pre-position a regional CAT team on a 5-percent watch probability.

Hotspot 3 — Lower Colorado / San Bernardino isolated SVR

SPC still withholds unconditional severe probabilities for southeast California, southern Nevada, and western Arizona, but NWS Las Vegas issued a Severe Thunderstorm Warning at 129 PM PDT Monday for San Bernardino County until 215 PM PDT. Radar-indicated hazards: 60 mph gusts and quarter-size hail near Amboy and Interstate 40 between mile markers 68 and 98, storm moving northeast at 20 mph. That warning is a short local pulse inside the WPC flood overlay, not an SPC watch.

Restoration read: check I-40 desert ZIPs and any hail-struck vehicles after the cell passes. The bigger ticket in that same corridor remains flash-flood water, not wind.

Just hit

SPC local storm reports for the current 1200 UTC Monday to 1159 UTC Tuesday window showed no tornado, hail, or wind reports as of this afternoon desk. That board resets at 12Z. Last night’s preliminary reports from the 27/1200–28/1159 UTC window remain the open tickets:

2216 UTC Sunday — 1.00-inch hail 20 miles south of Merriman, Cherry County, Nebraska. Vehicle damage reported. (NWS North Platte)
2330 UTC Sunday — 1.00-inch hail 2 miles north-northwest of Willow Park, Parker County, Texas. (NWS Fort Worth)
0032 UTC Monday — 1.00-inch hail 24 miles north of Whitman, Cherry County, Nebraska. (NWS North Platte)
1440 UTC Sunday — 66 mph gust 10 miles northwest of Okobojo Creek Recreation Area, Sully County, South Dakota. Mesonet. (NWS Aberdeen)
2300 UTC Sunday — 60 mph gust 22 miles west-southwest of Roosevelt, Sutton County, Texas. West Texas Mesonet Sonora 23SE. (NWS San Angelo)
2320 UTC Sunday — Unknown-speed wind 4 miles north-northwest of Willow Park, Parker County, Texas. Large tree limbs down on FM 730. (NWS Fort Worth)

No tornado reports were received in that window. Sunday evening Severe Thunderstorm Warnings over southwestern Cherry County, Nebraska, and northeastern Parker County, Texas, have expired. Today’s San Bernardino warning is a live local product, not yet an LSR.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this afternoon
Southwest / Four Corners	Flash flood, training rain, burn-scar runoff	WPC Moderate excessive rainfall	Live through Tuesday 12Z; outline expanded to CA/AZ/NV tripoint
Western / northern South Dakota	Isolated hail, gusty wind	SPC Marginal; MD 2330 watch unlikely	This afternoon into evening
Eastern Dakotas / NW Minnesota	Training showers, localized flood	WPC Slight excessive rainfall	Ongoing
SE CA / southern NV / western AZ	Numerous storms, isolated wet downburst or SVR	General thunder; local SVR San Bernardino	Today into evening
Cherry County, NE / Parker County, TX	Quarter hail, tree limbs	Expired SVR / Sunday LSRs	Just-hit cleanup
Polo	Baja wind and flood; U.S. moisture feed	NHC major hurricane near Baja Sur	Not a CONUS landfall

What this means for restoration teams

The national severe map is no longer blank, but it is still a small Marginal. The work that actually fills trucks today is WPC Moderate water on the Southwest and Four Corners. Saturated soils plus burn-scar fans do not need a supercell. Stage extraction before the next training core, not after the first flash-flood warning.

South Dakota is isolated hail and outflow if the Black Hills cells organize. MD 2330 says watch unlikely. Staff it as a local pulse. Cherry County and Willow Park remain yesterday’s hail and limb tickets. Photograph vehicles and roofs in daylight if it is still safe.

Polo is a Baja and Sonora hurricane desk plus a U.S. flood-moisture feed. Do not staff it as a California or Arizona landfalling hurricane. Nolo is a Central Pacific desk.

What this is not

This is not a Slight or Enhanced severe day, not a derecho, and not a U.S. mainland hurricane landfall. Work today, if it verifies, is flash flooding on the Four Corners Moderate, a narrow Dakotas Marginal, and one desert SVR in San Bernardino County. That is the local-storm pattern this desk should staff.

Looking ahead

SPC Day 2, issued 1215 PM CDT Monday and valid 12Z Tuesday through 12Z Wednesday, is a Marginal Risk from southern and eastern New Mexico into west Texas. Isolated severe gusts and a couple of tornadoes are possible Tuesday afternoon through early Wednesday as Polo remnants eject toward far west Texas and southeast New Mexico. Day 3 is already a Slight. WPC keeps Moderate flood language into Tuesday over parts of the Southwest, central and southern Rockies, and southern High Plains. Watch Tuesday morning Storm Tracker rather than assuming today’s small map is the week.

September 28, 2026

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.

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 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.

Storm Updates: New Mexico Flood Moderate, Utah–Southeast Marginal — Tuesday, September 22, 2026

This is a live Tuesday afternoon snapshot of U.S. local-storm activity as of Tuesday, September 22, 2026. The organized flood desk remains over southern New Mexico. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook still holds two Marginal Risk corridors — much of Utah into adjacent Wyoming and Colorado, and a portion of the Southeast that the 20Z update shifted farther south and east into central Georgia and southern Alabama. No convective watches are currently valid. Restoration exposure this afternoon into tonight is water first in southern New Mexico and far west Texas, isolated severe wind and marginally severe hail on the Utah corridor, locally severe gusts plus leftover flood axes in the Southeast and central Appalachians, and tree/wire work already on the board in Lauderdale County, Alabama.

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 this afternoon. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll. Morning desk: Storm Updates September 22, 2026 (Morning).

What is live this afternoon

SPC’s 2000 UTC Day 1 Convective Outlook (issued 2:56 p.m. CDT Tuesday, September 22, 2026; Halbert/Lyons; valid 222000Z–231200Z) keeps a Marginal Risk for much of Utah into adjacent Wyoming and Colorado, and across a portion of the Southeast. Summary: isolated severe wind gusts expected today in Utah into southwest Wyoming and western Colorado; thunderstorms capable of strong to locally severe damaging gusts also possible across parts of the Southeast. The 20Z update moved the Southeast Marginal farther south and east into central Georgia and southern Alabama, where storms had already developed in an unstable airmass with steep low-level lapse rates.

No convective watches were currently valid as of the SPC watches page update at 15:56:05 UTC Tuesday, September 22, 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 1553 UTC Tuesday, September 22, 2026; Taylor/Chenard; valid 16Z Tue–12Z Wed) still holds a Moderate Risk across portions of southern New Mexico. WPC notes a potentially significant multi-day flood event over New Mexico and far southwest Texas, with 1–2 inches per hour rain rates this afternoon and training bands tonight. Neighborhood guidance: moderate chance of at least 3 inches (about 40–60 percent) and a low chance of at least 5 inches. Slight Risk axes remain over central to southeast Virginia into South Carolina and West Virginia into southwest Virginia. South Florida stays a WPC Marginal urban-flood desk.

Live warning-scale water this afternoon includes NWS flash-flood warnings for parts of Lincoln/Socorro, Doña Ana/Otero in New Mexico, and Randolph/Webster in West Virginia — already hung as separate Tygart Media warning pulses. NWS also had a flood advisory for west-central Lee County, Alabama (Auburn/Opelika) into late afternoon and a severe thunderstorm warning earlier over Jackson and DeKalb Counties, Alabama.

Hotspot 1 — Southern New Mexico / far west Texas

Still the national flood desk. An upper trough, jet right-entrance dynamics, deep southerly moisture, and precipitable water toward mid/late September record levels support a multi-day event. Afternoon is scattered thunderstorms and flash-flood potential; overnight guidance concentrates a rain shield with heavier cores over southern New Mexico. Sacramento Mountains burn scars remain in the higher-impact language. Flash-flood warnings this afternoon already covered Lincoln, Socorro, Doña Ana, and Otero Counties.

Restoration read: water first, overnight worse than the afternoon pulse. Stage pumps and air movers before the shield organizes. Low-water crossings and burn-scar runoff fail first. Start extraction the same night if water is inside.

Hotspot 2 — Utah into southwest Wyoming and western Colorado

SPC Marginal wind-and-hail corridor is the afternoon convective desk in the West. A potent shortwave over the western Great Basin and a belt of stronger mid-level flow from northern Arizona into central and northern Utah support scattered to numerous storms. Buoyancy stays modest (MLCAPE generally under 1,000 J/kg), but shear and cold mid-levels support organized cells, isolated large hail, and strong gusts off high bases and steep low-level lapse rates. Activity can spill into western Colorado and southwest Wyoming late afternoon into early evening. Larger centers inside the earlier outlook footprint include Salt Lake City, West Valley City, Provo, West Jordan, and Orem.

Restoration read: wind and isolated hail, not a flood CAT. Stage tarps, generators, and tree crews before early evening. Soft-metal roofs and skylights after stronger cores only if it is safe.

Hotspot 3 — Southeast / southern Appalachians

SPC Marginal for the Southeast is a slow-moving cold front into a moist airmass. The 20Z update pulled the risk south and east into central Georgia and southern Alabama, matching storms already on radar. Weak shear keeps the mode multicellular and outflow-dominant; water-loaded downdrafts can still put 50–60 mph gusts on the ground. Today’s preliminary LSRs already show Lauderdale County, Alabama wind damage: power lines down west of Lexington around 1814 UTC, a power pole and lines on a vehicle west of Rogersville around 1835 UTC, and lines down at Lauderdale County High School and the adjacent parking lot around 1856 UTC (NWS Huntsville).

WPC Slight flood axes remain over southeast Virginia into South Carolina and West Virginia into southwest Virginia, where soils are already wet and flash-flood guidance is lower. Randolph and Webster Counties, West Virginia, carried a live flash-flood warning into the evening.

Restoration read: gusty wind and street flooding can share the same ZIP. Alabama tree and wire jobs are already tickets. Charlotte-to-Atlanta language from this morning is not a derecho — treat each county warning as a local pulse.

Just hit

SPC preliminary local storm reports for the 22/1200 UTC–23/1159 UTC window (as of this afternoon hang) show no tornado reports and no hail reports yet. Wind reports on the board are Lauderdale County, Alabama: lines down 3 W Lexington; pole and lines on a vehicle 2 W Rogersville; lines down at Lauderdale County High School in Rogersville. Those are already restoration tickets — trees, wire, and possible vehicle/roof work — not a regional outbreak.

Monday night’s Appalachians–Southeast flash-flood pulse is aftermath. This afternoon’s live water is New Mexico and pockets of West Virginia, plus a Lee County, Alabama flood advisory earlier this afternoon.

Pulse table

Region	Main threats	SPC / WPC / NWS level	Status this afternoon
Southern NM / far west TX	Flash flood, training rain tonight, burn-scar runoff	WPC Moderate + live FFWs	Live flood desk today–Wed
Utah into SW WY / western CO	Severe wind gusts, isolated large hail	SPC Marginal	Afternoon–early evening
SE / central GA / southern AL	Locally severe damaging gusts, trees/wire	SPC Marginal (shifted S/E at 20Z)	Live; AL LSRs already in
SE VA into SC; WV into SW VA	Flash flood / heavy rain	WPC Slight + WV FFWs	Today into tonight
South Florida	Urban flash flood	WPC Marginal	Local
U.S. mainland tropics	No landfalling tropical cyclone	NHC quiet for mainland	Quiet

What this means for restoration teams

Southern New Mexico is the water CAT if the Moderate risk verifies overnight — extraction, drying, and a 24–48 hour mold clock. Utah’s Marginal corridor is wind and isolated hail. Southeast Marginal wind is already producing Lauderdale County tickets; treat Georgia and Alabama warnings as local, not a derecho. West Virginia water is a second flood desk on already-wet ground. Stage New Mexico before the overnight shield. 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. Post-tropical Fay is open Atlantic near the Azores and is not a U.S. land threat. Hurricane Polo and Tropical Storm Odalys remain eastern Pacific systems and are not mainland landfall threats today. No convective watches are up. Do not invent a named CAT for Restoration Intel off this pulse.

Looking ahead

SPC’s current Day 2 outlook (Wednesday, September 23) is Marginal Risk as of the 1719 UTC issuance (Dean). Day 3 is currently no severe thunderstorms. That does not cancel tonight’s New Mexico flood problem or this evening’s Utah and Southeast Marginal corridors. Watch the next Storm Tracker update rather than assuming the Moderate rainfall risk is the last line of the week.

Storm Updates: Idaho–Utah Marginal, Dakotas Flood Slight — Thursday, September 17, 2026

This is a live Thursday afternoon snapshot of U.S. local-storm activity as of Thursday, September 17, 2026. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook holds a Marginal Risk of isolated severe wind gusts and hail this afternoon and evening over parts of Idaho and Utah and a small part of the central High Plains. No convective watches are valid. Mesoscale Discussion 2304 covers southern and central Idaho with a 20 percent chance of a watch. The Weather Prediction Center Day 1 Excessive Rainfall Outlook remains the organized ticket: Slight Risk over portions of the north-central Plains and Midwest and over the southwestern U.S. There is no named tropical cyclone in the Atlantic, eastern Pacific, or central Pacific.

These are county- and ZIP-scale thunderstorms and flash-flood pulses, not a mainland hurricane landfall. Restoration exposure this afternoon is isolated hail and wind if cells verify over the Snake River Plain and Wasatch Front, plus water from the Wyoming Front Range across South Dakota into southwest Minnesota and leftover Southwest terrain. Conditions change fast. 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 Day 1 Convective Outlook at 0247 PM CDT, valid 172000Z–181200Z. Forecasters Chalmers and Weinman made no changes from the midday package. Headline: thunderstorms with isolated severe wind gusts and hail will be possible over parts of the Intermountain West this afternoon and evening. A few strong to severe gusts may also occur across portions of the central High Plains. Risk-area population centers listed by SPC include Salt Lake City, West Valley City, Provo, West Jordan, and Orem. Categorical risk is Marginal only. No Slight Risk. No tornado probabilities in the 2000 UTC package. The Ohio Valley Marginal from Wednesday remains off the map.

Current convective watches: none. SPC watch page last updated 2059 UTC Thursday: no watches currently valid. Most recently issued watch remains Severe Thunderstorm Watch 669, already expired. Do not treat 669 as a live product.

MCD 2304, issued 0246 PM CDT and valid 1946Z–2215Z, covers parts of southern and central Idaho. Concerning: severe potential, watch unlikely. Probability of watch issuance: 20 percent. Summary: the risk of a few severe storms capable of producing large hail and severe wind gusts will increase through the remainder of the afternoon. Most probable peak wind gust 55–70 mph. Most probable peak hail size 1.00–1.75 inches. Offices tagged: Pocatello, Missoula, Boise. By late afternoon the live MD list showed no mesoscale discussions currently in effect; treat 2304 as the latest issued discussion, not a standing watch.

WPC Day 1 excessive-rainfall language valid 12Z Thursday through 12Z Friday still has two Slight Risk corridors. One is a high-end Slight across much of South Dakota, expanding toward Sioux Falls and into southwestern Minnesota and northwest Iowa, and west-southwest to the Cheyenne, Wyoming region east of the Laramie Range. The other holds Slight Risk over New Mexico and eastern Arizona into the San Juans and western Colorado, with Marginal coverage into the Salt Lake corridor and southeastern Idaho. Wednesday’s Moderate Risk over southern and central Arizona is aftermath, not a live upgrade.

Hotspot 1 — Southern and central Idaho into northern Utah

Morning water vapor showed an upper low over northern California with a band of strong flow aloft and embedded shortwave troughs across Nevada into Utah and Idaho. Strong heating was expected to aid scattered thunderstorms from southern Idaho into northern Utah by mid-afternoon. Sufficient vertical shear is present for rotating updrafts capable of large hail and gusty or damaging winds. Coverage is limited. SPC still expects one or two severe cells later today, mainly over the eastern Snake River Plain. The 18Z Boise sounding in MCD 2304 sampled steep deep-layer lapse rates and an elongating, mostly straight hodograph with about 30–40 kt of cloud-layer shear. Cells first. Small clusters later if outflow organizes.

Overnight LSRs already put quarter-size hail at Huntington in Emery County and at East Carbon and Sunnyside in Carbon County. That is the same Salt Lake City forecast office that owns this afternoon’s Utah cells.

Restoration read: hail first if discrete cells fire over the Snake River Plain, Boise, Pocatello, or the Wasatch Front. Wind second if storms cluster. Stage roof and auto-glass survey capacity before the first warning, not after. Flash-flood risk on this corridor is Marginal to isolated, not the organized Dakotas ticket.

Hotspot 2 — Dakotas water corridor and the High Plains wind overlay

Remnants of a weak tropical low tracked northeast across the Four Corners this morning. Ample moisture and weak ascent support considerable clouds and scattered thunderstorms over the Colorado mountains and southern Wyoming, spreading east into eastern Colorado and western Nebraska and Kansas. High-based convection poses a risk of locally damaging wind gusts. Daytime heating is the limiter because of lingering cloud cover. That is the SPC Marginal overlay: isolated gusts, not a Slight Risk wind event.

WPC is more organized here than SPC. A tropical-origin shortwave ejecting out of Arizona pivots through the central Rockies and into the northern Plains tonight. Precipitable-water anomalies approach the 95th–99th percentile from South Dakota into southern Minnesota by the end of the period. Discussion language includes 2–4 inches, locally higher, with HREF neighborhood probabilities of greater than 2 inches at 50–80 percent across a large High Plains swath. The centroid of greater-than-3-inch probabilities sits just east and southeast of Rapid City into Badlands National Park. The Slight Risk was expanded east toward Sioux Falls for the last 6–8 hours of the forecast.

Restoration read: water first from the Wyoming Front Range across western and central South Dakota into southwest Minnesota and northwest Iowa tonight into Friday morning. Wind second if High Plains clusters organize. Do not send one crew to both a Cheyenne gust and a Rapid City wash without checking which county has a warning now.

Hotspot 3 — Southwest terrain leftover plus Ohio just-hit

The shortwave that drove Wednesday’s Arizona Moderate flood risk is leaving. WPC still keeps a Slight Risk over New Mexico and eastern Arizona into the San Juans and Sacramentos. Guidance still prints 1–3 inches on the Sangre de Cristos, San Juans, and interior New Mexico terrain. Sacramento Mountains burn-scar sensitivity remains in the discussion as locally Moderate impacts embedded inside a higher-end Slight. That is runoff on ground that already took water Wednesday, not a new Moderate upgrade.

Ohio is off today’s SPC Marginal. It is the just-hit desk. Overnight LSRs from the 16/1200Z–17/1159Z window include multiple trees down in Versailles and Piqua, a snapped hardwood onto a home awning in Darke County, barn sheet-metal loss and a blown silo near West Alexandria in Preble County, and trees and wires southeast of Mansfield in Richland County. NWS Cleveland had severe thunderstorm warnings into mid-evening Wednesday for Richland, Ashland, Holmes, and Knox counties. Those products are expired. The trees are still on the lines.

Just hit

SPC preliminary storm reports for the current 17/1200Z–18/1159Z cycle show no tornado, hail, or wind reports as of this afternoon desk. That is expected. The Intermountain and High Plains threats are still an afternoon and evening problem.

The last 24-hour ticket pile sits on the prior cycle (16/1200Z–17/1159Z): no tornadoes. Hail: 1.00 inch at Huntington, Emery County, Utah; 1.00 inch at East Carbon and Sunnyside, Carbon County, Utah; 1.00 to 1.25 inches near Linn Creek, Camden County, Missouri, with two-foot-diameter limbs down. Wind: downed power lines in Mesa, Maricopa County, Arizona; trees in Versailles, Darke County, and Piqua and Lockington, Miami County, Ohio; a snapped pole and large limb near Broken Arrow, Tulsa County, Oklahoma; a power line and a condo-garage roof near Osage Beach and Linn Creek, Missouri; barn roofing and a grain silo near West Alexandria, Preble County, Ohio; trees and wires southeast of Mansfield.

This morning’s Storm Tracker already covered the same outlook family at 1300 UTC. This afternoon desk updates to the 2000 UTC package, adds MCD 2304, and confirms still-zero watches and still-zero LSRs on today’s cycle.

What this means for restoration teams

Isolated severe hail on the Snake River Plain and Wasatch Front is a roof and auto-glass survey ticket if cells verify over Boise, Pocatello, Salt Lake, or Provo. Isolated High Plains gusts are tree, siding, and gutter work in a thin corridor. The organized ticket today is still water from the Wyoming Front Range across South Dakota into southwest Minnesota and northwest Iowa tonight. Flash flooding on leftover Arizona–New Mexico terrain is wet drywall and a same-night extraction clock if water is inside a structure that already took rain Wednesday. Ohio trees-on-wires from last night are a separate staffing problem from this afternoon’s West.

For teams near the Intermountain Marginal: stage before mid-afternoon local. Property owners should 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 on High Plains and Southwest washes.

What this is not

This is not a Slight Risk severe day, not a live convective watch, and not a U.S. mainland hurricane landfall. MCD 2304 is watch-unlikely, not a watch. NHC reports no tropical cyclones in the Atlantic, eastern Pacific, or central Pacific as of this afternoon. The work, if it verifies, will be scattered: a hail swath through an Idaho or Utah county, a gust cluster on the High Plains, and heavier rain over South Dakota terrain tonight.

Looking ahead

SPC Day 2 (Friday, 1730 UTC package) holds Marginal Risk of isolated severe storms across parts of Idaho and Utah, Nebraska and Iowa, and the Piedmont of the Carolinas into north Georgia. Population centers listed on that outlook include Charlotte, Atlanta, Omaha, Lincoln, and Greensboro. WPC’s Day 1 water corridor over the Dakotas is the bridge into the Plains Marginal. The next Storm Tracker update should re-check the 0100 UTC Day 1 outlook and any new watches rather than assuming this afternoon’s Marginal stays the last word.
