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.

Sources and how to verify

Primary sources dated Thursday, September 24, 2026: NOAA Storm Prediction Center 1630 UTC Day 1 Convective Outlook; SPC current watches page (no valid watches as of 2107 UTC); SPC today and September 23 storm-report pages; Weather Prediction Center Day 1 Excessive Rainfall Outlook and 417 PM EDT discussion (Moderate Risk, southeast New Mexico); WPC Mesoscale Precipitation Discussion 1375 (Pecos River Valley); WPC Day 2 ERO; SPC 1730 UTC Day 2 outlook; National Hurricane Center / CPHC advisory board for Tropical Storm Nolo, Tropical Storm Fay, Hurricane Polo, and Hurricane Odalys; National Weather Service warning text including the overnight Dodge City flash-flood warning.

September 24, 2026

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.

Pulse table

Region	Main threats	SPC / WPC / NWS level	Status this morning
Central / eastern NM and far west TX	Flash flood, training storms, burn-scar runoff	WPC Moderate	Live flood desk today–Thu 12Z
Southeast AZ	Localized flash flood	WPC Slight	Today
Eastern KY / eastern TN / far western NC	Flash flood + isolated damaging gusts	WPC Slight + SPC Marginal	Afternoon–evening
Western Dakotas / Black Hills	Isolated hail / gusts	SPC Marginal	Late afternoon–early evening
OH into WV / western VA–NC	Localized flash flood on wet soils	WPC Marginal	Today
South Florida	Urban flash flood	WPC Marginal	Local
El Paso / central VA / WNC overnight	Flash flood (expired/expiring FFWs)	Overnight NWS warnings	Aftermath / receding
U.S. mainland tropics	No landfalling named cyclone	NHC quiet for CONUS land	Quiet

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.

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: New Mexico Flood Moderate, Utah–Southeast Marginal — Tuesday, September 22, 2026 (Morning)

This is a live Tuesday morning snapshot of local storm-type events across the United States as of the morning of Tuesday, September 22, 2026. Overnight, the Appalachians–Southeast corridor carried the pulse — NWS Charleston, West Virginia flash-flood warnings for southern and north-central West Virginia into southwest Virginia. Those overnight warnings are treated as expired/expiring into this morning (no active WV flash-flood warnings on the NWS alert feed at hang time). Today’s desks: Storm Prediction Center Marginal Risk for much of Utah into adjacent Wyoming and Colorado, plus a portion of the Southeast; Weather Prediction Center Moderate Risk of excessive rainfall across portions of southern 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 U.S. landfalling tropical cyclone in the current National Hurricane Center picture. Restoration exposure today into tonight is water first in southern New Mexico and far west Texas, wind and marginally severe hail this afternoon across the Utah corridor, leftover Appalachian water from Monday night, and locally severe gusts plus flood axes across parts of the Southeast and Mid-Atlantic. 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 7:22 a.m. CDT Tuesday, September 22, 2026; Smith/Mead; valid 221300Z–231200Z) places a Marginal Risk over much of Utah into adjacent Wyoming and Colorado, and across a portion of the Southeast. Summary: isolated severe wind gusts 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. Outlook footprint ~196,000 square miles / ~24 million people. Larger Southeast centers in the risk area include Charlotte, Atlanta, Greensboro, Birmingham, and Montgomery.

No convective watches were currently valid as of the SPC watches page update at 11:44:05 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 0809 UTC Tuesday, September 22, 2026; Chenard; valid 12Z Tue–12Z Wed) holds a Moderate Risk across portions of southern New Mexico, with flood watches from noon MDT today through Wednesday afternoon/evening for large parts of New Mexico and far west Texas (NWS Albuquerque and El Paso/Santa Teresa). WPC Slight axes: southeast Virginia into South Carolina, and West Virginia into southwest Virginia. South Florida: WPC Marginal for localized urban flash flood.

Hotspot 1 — Southern New Mexico / far west Texas

Today’s Moderate flood desk. Multi-day heavy rain starts today under an upper trough, jet right-entrance dynamics, deep southerly tropical moisture, and precipitable water toward mid/late September record levels. Daytime favors scattered storms; overnight trends toward a more concentrated rain shield with heavier cores over southern New Mexico. Ensemble neighborhood guidance: 40–70% chance of more than 3 inches across New Mexico today; 2–4 inch max footprint through early Wednesday. Scattered to numerous flash floods expected, some locally significant, including Sacramento Mountains burn scars.

Restoration read: water first. Stage pumps and air movers before the overnight shield organizes. Burn-scar runoff and low water crossings 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. Mid-level trough over the western Great Basin moves northeast across Utah through early evening. After early showers, heating steepens 0–2 km lapse rates; elongated hodographs support a few stronger cells with marginally severe hail. Isolated 60–75 mph gusts are the primary hazard. Activity can later spill into western Colorado and southwest Wyoming late afternoon into early evening.

Restoration read: wind and isolated hail. Stage tarps, generators, and tree crews before late afternoon. Soft-metal roofs and skylights after stronger cells only if it is safe.

Hotspot 3 — Southeast / southern Appalachians, plus Mid-Atlantic flood axes

SPC Marginal for the Southeast focuses on a slow-moving cold front from the Deep South into the southern Appalachians. Dewpoints upper 60s–lower 70s °F; afternoon MLCAPE about 1,500–2,500 J/kg. Weak shear; water-loaded downdrafts can produce locally severe gusts into early evening.

WPC Slight flood axes: southeast Virginia into South Carolina (coastal convergence + backdoor front; neighborhood high for 3 inches, localized 5 inches possible) and West Virginia into southwest Virginia (wetter soils, lower flash-flood guidance, inverted trough). Farther north Mid-Atlantic: more stratiform 1–2 inches. South Florida WPC Marginal is a local urban-flood desk, not the national headline.

Restoration read: gusty wind and street flooding can share the same ZIP. Charlotte, Atlanta, Greensboro, Birmingham, and Montgomery sit inside the broader Southeast convective risk — local pulse desks, not a regional derecho.

Just hit

Monday afternoon into overnight, the Appalachians–Southeast carried the live severe and flash-flood pulse (already on yesterday’s afternoon Tygart Media desk). Overnight NWS Charleston, West Virginia flash-flood warnings covered southern West Virginia / southwest Virginia (Welch, Pineville, Davy, McDowell, Wyoming, Buchanan; 1–3 inches radar-indicated) and north-central West Virginia along Buckhannon–Burnsville–Century / I-79 (1–3 inches). Those overnight warnings are treated as expired or expiring into this morning. No clean parsed SPC LSR list in this pass — do not invent points.

Pulse table

Region	Main threats	SPC / WPC / NWS level	Status this morning
Southern NM / far west TX	Flash flood, multi-day heavy rain, burn-scar runoff	WPC Moderate + flood watches	Live flood desk today–Wed
Utah into SW WY / western CO	Severe wind gusts, marginally severe hail	SPC Marginal	Afternoon–early evening

Appalachians–Southeast overnight	Flash flood (yesterday’s pulse)	Overnight FFWs (expired/expiring)	Aftermath / drying
U.S. mainland tropics	No landfalling tropical cyclone	NHC quiet for mainland	Quiet

What this means for restoration teams

Southern New Mexico and far west Texas are water jobs if the Moderate risk verifies — extraction, drying, and a 24–48 hour mold clock. Utah’s Marginal corridor is wind and isolated hail. Southeast Marginal wind is local gusty warnings, not a derecho. Leftover Appalachian water from Monday night is aftermath. Stage before the overnight New Mexico rain 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. Tropical Depression Fay is mid-Atlantic open ocean and becoming post-tropical — not a U.S. land threat. Hurricane Polo and Tropical Storm Odalys remain eastern Pacific systems and are not mainland landfall threats today. Today’s work, if it verifies, is scattered: southern New Mexico flash flood, Utah–Colorado wind/hail, Southeast gusts, leftover Appalachian water.

Looking ahead

SPC Day 2 and Day 3 currently show no severe thunderstorm areas. That does not cancel tonight’s New Mexico flood problem or this afternoon’s Marginal corridors. Watch the next Storm Tracker update rather than assuming the Moderate rainfall risk is the last line of the week.

Storm Updates: Appalachians–Southeast Marginal + Central Appalachians Flood Slight — Monday, September 21, 2026

This is a live Monday afternoon snapshot of U.S. local-storm activity as of Monday, September 21, 2026. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook holds a Marginal Risk of severe thunderstorms from parts of the Southeast into the central Appalachians and over the Texas South Plains. No convective watches are currently valid. The Weather Prediction Center maintains a Slight Risk of excessive rainfall over portions of the central Appalachians. Scattered severe thunderstorm warnings and flash-flood warnings remain active this afternoon across portions of the Tennessee Valley, Carolinas, Alabama, and West Virginia.

These are county- and ZIP-scale thunderstorms and localized heavy-rain pulses, not a mainland hurricane landfall or organized derecho. Restoration exposure this afternoon and evening is wind-driven tree and roof work, isolated hail, and interior water where cells train or flash-flood warnings verify. 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 Marginal Risk covers the Southeast into the southern and central Appalachians, with isolated damaging wind gusts of 50–60 mph the primary threat. A second Marginal area sits over the Texas South Plains where isolated large hail and severe gusts remain possible later today. Mesoscale Discussion 2323 (issued 1938 UTC) covers the Texas South Plains into the Permian Basin and notes watch issuance is unlikely; strongest storms may briefly produce large hail up to 1.25 inches and marginally severe wind.

WPC’s Day 1 Excessive Rainfall Outlook keeps a Slight Risk over the central Appalachians (expanded earlier to include more of West Virginia and southwest Virginia). Guidance supports 1–3 inches with locally higher amounts where cells train near a backdoor cold front and shortwave energy. Flash Flood Warnings and Flood Warnings remain active or recently expired across portions of West Virginia, Ohio, and adjacent counties from overnight and early-morning convection.

Hotspot 1 — Central Appalachians and Mid-Atlantic fringe (WPC Slight + SPC Marginal)

This is the dual-threat corridor. Scattered thunderstorms continue along and south of a cold front stretching from southern Virginia west-northwest into northern Kentucky and southwestward. Highest coverage expected from southeast Tennessee and northwest Georgia through northern Alabama into central/southern Mississippi and eastern Louisiana, with additional activity into southwest Virginia and West Virginia. Vertical shear is weak; storm mode is largely multicellular and outflow-dominant, but ample moisture (PW values over 2 inches) supports strong to locally severe gusts and flash flooding on saturated soils.

Cities and counties to watch: Charleston, Parkersburg, and surrounding West Virginia counties; southwest Virginia counties including Giles, Mercer, and Summers; portions of eastern Kentucky and southern Ohio; Chattanooga and Knoxville metro fringes in Tennessee; northern Alabama counties including Madison and Marshall.

Restoration read: wind and water both in play. Stage tarps, generators, and tree crews. Flash-flood warnings mean extraction and drying work may already be on the books by evening. Photograph roofs in remaining daylight only if it is safe.

Hotspot 2 — Texas South Plains and northeast Texas

Isolated to widely scattered storms continue near the intersection of a weak surface trough and cold front across the Texas South Plains into the Permian Basin. MD 2323 flags the potential for brief severe storms capable of large hail and marginally severe wind before dissipation this evening. A secondary area of higher thunderstorm coverage is expected over northeast Texas this afternoon and evening, where water-loaded downbursts capable of damaging wind gusts are possible.

Cities and counties to watch: Lubbock, Midland, and surrounding South Plains counties; portions of northeast Texas near the Red River. Local Severe Thunderstorm Warnings have already fired this afternoon in the region.

Restoration read: hail and wind first. Check vehicle and roof damage reports quickly; these are short-lived cells but can produce ticket-scale damage in a single ZIP.

Hotspot 3 — Southeast scatter (Carolinas, Georgia, Alabama, Mississippi)

Ongoing multicell storms continue to produce local Severe Thunderstorm Warnings with 60 mph wind and small to quarter-size hail. Coverage is highest from southeast Tennessee and northwest Georgia through northern Alabama into central/southern Mississippi and eastern Louisiana. Storms are moving relatively slowly or nearly stationary in places, increasing the local flash-flood and wind-damage potential.

Cities and counties to watch: Chattanooga, Huntsville, Birmingham metro areas; portions of the Carolinas and northern Georgia where warnings have been active this afternoon.

Restoration read: scattered wind and tree damage plus isolated water jobs. Treat each warning county as its own ticket rather than a regional event.

Just hit

Overnight and early-morning convection produced Flash Flood Warnings across portions of West Virginia and southeast Ohio, with residual river and stream rises still ongoing in some gauges. Yesterday’s High Plains activity (eastern Colorado into western Kansas) produced large hail reports up to baseball size and is already in the ticket pipeline for those counties. Local wind damage reports from trees and power lines continue to filter in from the Ohio Valley, Illinois, Missouri, Georgia, Alabama, and the Carolinas. No new U.S. mainland tropical cyclone threat is in the National Hurricane Center outlook at this hour.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
Central Appalachians / WV–SW VA	Flash flood, damaging wind, trees	WPC Slight + SPC Marginal	Live warnings + overnight residual
Southeast / TN–AL–GA–MS–Carolinas	Damaging wind, isolated hail, lightning	SPC Marginal + local SVR	Scattered warnings active
Texas South Plains / NE TX	Large hail, severe gusts	SPC Marginal + MD 2323	Isolated cells, watch unlikely
Ohio Valley residual	Flooding from earlier rain	Local Flood Warnings	Aftermath / still in channel
Atlantic / Gulf vs. U.S. mainland	No landfalling tropical cyclone	Quiet on the mainland coast	Quiet

What this means for restoration teams

Wind at 50–60 mph is roof, siding, gutter, and tree-on-structure work. Hail on the South Plains is vehicle and roof impact. Heavy rain on the central Appalachians Slight Risk is wet drywall and a 24–48 hour mold clock where flash flooding verifies. Overnight West Virginia and Ohio water is already inside some buildings.

For teams near active warnings: stage before the next cell arrives, not after the first report. Property owners should photograph damage 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. The work this afternoon and evening, if it verifies, will be scattered: a wind swath through a Tennessee or West Virginia county, a flooded intersection where Appalachian cells train, isolated hail on the South Plains. That is the local-storm pattern this desk should staff.

Looking ahead

Tuesday the front continues to push south and east with another Marginal Risk possible over portions of the Southeast. Residual flooding in the central Appalachians may linger into Tuesday morning. Watch the next Storm Tracker update rather than assuming today’s Marginal and Slight Risk areas are the last line of the week.

September 21, 2026

Storm Updates: Appalachians–Southeast Marginal, Texas South Plains Hail Pulse — Monday, September 21, 2026 (Morning)

This is a live Monday morning snapshot of U.S. local-storm activity as of early Monday, September 21, 2026. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook holds a Marginal Risk of severe thunderstorms from parts of the Southeast into the central Appalachians, and a second Marginal Risk over the Texas South Plains. Isolated damaging wind gusts of 50 to 60 mph are the main threat along the front this afternoon. Isolated large hail and severe gusts are possible later today on the Caprock. No convective watches are currently valid. Severe Thunderstorm Watch 674, last night’s eastern Colorado and extreme western Kansas box, has expired.

These are county-scale thunderstorms, not a U.S. mainland tropical landfall. Tropical Storm Fay is several hundred miles southwest of the Azores and is not a U.S. land threat. Restoration exposure today is leftover tree and roof work from last night’s Ohio Valley and High Plains cells, plus a new wind-damage pulse if the front fires this afternoon from Kentucky into West Virginia and Virginia. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

Overnight into this morning

Radar this morning shows a parade of three mesoscale convective vortices moving east over the Ohio Valley into the central Appalachians, mostly on the cool side of a cold front. That is leftover organization from Sunday night, not a new watch. Local storm reports on the SPC day that closed at 12 UTC Monday include no tornadoes. The hail corridor was eastern Colorado: golf-ball to baseball-size stones around Holyoke, Alvin, Genoa, Boyero, Wild Horse, Kit Carson, Eads, and south of Brandon in Phillips, Yuma, Lincoln, Cheyenne, and Kiowa counties. One social-media measurement near Brandon was 3.10 inches. A spotter windshield was damaged near Wild Horse. A separate 2.00-inch hail report came from Liberty in Union County, Indiana.

Wind reports overnight were the restoration ticket east of the High Plains. Trees and lines came down across Christian, Greene, Jasper, and Lawrence counties in southwest Missouri, including a tree on a house in Pierce City. Illinois reports included a shed roof in Jasper County, 64 mph at Olney-Noble Airport, and power-line damage near Witt, Ramsey, and Noble. Southwestern Ohio logged trees in Kettering, Bellbrook, and Greene County after midnight. After 3 UTC, NWS Charleston territory picked up trees and blocked roads in Vinton and Meigs counties, Ohio, and in Wirt, Calhoun, and Gilmer counties, West Virginia, including more than 1,200 customers without power along Highway 7 north-northeast of Syracuse. Separate tree-down reports ran through Anderson and Laurens counties in South Carolina, Walton County, Georgia, and a string of Alabama, Georgia, and Florida Panhandle counties from Taylor and Iron City to De Funiak Springs and I-10 mile marker 70.

Flash flood warning posts already on this desk overnight covered pieces of Muskingum, Washington, Morgan, and Gallia counties in Ohio and Braxton plus north-central West Virginia. Those warnings were timed to expire in the early morning hours. Treat them as just-hit water, not a new outlook. Confirm county status on weather.gov before you treat a warning as still live.

What is live this morning

No SPC watches are valid as of 1136 UTC Monday. The Day 1 outlook valid 1300 UTC Monday through 1200 UTC Tuesday is Marginal only. The front this afternoon is forecast from northern Mississippi northeast to western Virginia. Dewpoints ahead of it run upper 60s to lower 70s from the lower Mississippi Valley into West Virginia. SPC expects scattered to numerous single-cell and multicell storms after peak heating, with the better flow on the northern edge of the risk — Kentucky, West Virginia, and Virginia. Stronger downdrafts can produce 50 to 60 mph gusts and pockets of wind damage before cells weaken in the early evening.

The Texas South Plains Marginal is a separate, isolated pulse. A front and residual outflow drape the Caprock this afternoon. Guidance supports scattered storms in a moist plume during peak heating, with a couple of stronger cells capable of large hail and severe gusts before they die in the evening.

The Weather Prediction Center Day 1 Excessive Rainfall Outlook page still carried Sunday’s discussion into the 12 UTC Monday valid end, with Slight Risk language over portions of the Midwest and Ohio Valley plus the northern High Plains from the prior period. That is the moisture that already produced last night’s Ohio–West Virginia flood warnings. Use the live WPC graphic and local NWS flash-flood products for today’s water overlay rather than treating Sunday’s Slight as a new box.

Hotspot 1 — Kentucky, West Virginia, Virginia, and the central Appalachians

This is the northern edge of today’s Marginal Risk and the part of the front with slightly stronger flow. Cities and counties to watch: Lexington and eastern Kentucky; Charleston, Huntington, Parkersburg, and the central West Virginia counties that already took trees overnight; western and northern Virginia including the Shenandoah and the Richmond-to-Charlottesville fringe of the outlook line. SPC maps the Marginal from near Greenville, Mississippi, northeast through Kentucky to near Parkersburg, then east toward Elkins, Charlottesville, and Richmond before dropping south through Raleigh and Athens toward Montgomery and Jackson.

Restoration read: wind first, water second. Last night already put trees on roads and lines in Meigs, Wirt, Calhoun, and Gilmer. Another round of 50–60 mph gusts this afternoon is more of the same — roof, siding, service drops — not a regional derecho. If a cell trains on ground that flooded overnight, treat that ZIP as a water job by evening.

Hotspot 2 — Southeast ahead of the front

The same Marginal Risk covers central Mississippi, Alabama, northern Georgia, and the western Carolinas. Instability can peak in the 2000 to 3000 J/kg range from central Mississippi into western North Carolina, but deep-layer shear is weak. Mode is single cells and disorganized multicells. Sunday evening already produced trees in Anderson and Laurens, South Carolina; Monroe and Walton, Georgia; and the Florida–Alabama line. Today is a repeat isolated-wind desk, not a watch.

Restoration read: stage locally if your county is on the warm side of the front. Do not move a regional crew on a Marginal that SPC itself frames as isolated 50–60 mph gusts.

Hotspot 3 — Texas South Plains, plus leftover High Plains hail

The second Marginal sits from near Clovis and Hobbs across the Caprock toward Childress and Big Spring. Isolated large hail and severe gusts later today are the threat. That is not last night’s Colorado supercell corridor. Last night’s work is already on the books in Cheyenne, Kiowa, Lincoln, Yuma, and Phillips counties — baseball hail, damaged glass, and agricultural hits. Do not send the same crew to Lubbock this afternoon and Eads this morning without checking which county actually has a warning now.

Just hit

Sunday afternoon’s High Plains Slight Risk and Watch 674 are closed. The verified story there is large hail, not a tornado. Southwest Missouri trees, Illinois wind, Ohio–West Virginia overnight trees and flash-flood warnings, and scattered Southeast wind reports are the other closed tickets. Tropical Storm Fay is not a U.S. land story.

Pulse table

Region	Main threats	SPC / NWS level	Status this morning
KY / WV / VA / central Appalachians	Isolated damaging wind 50–60 mph, lightning	SPC Marginal	Afternoon pulse; no watch
MS / AL / GA / western Carolinas	Isolated wind, wet microbursts	SPC Marginal	Diurnal; no watch
Texas South Plains / Caprock	Isolated large hail, severe gusts	SPC Marginal	Late afternoon–evening
Eastern Colorado High Plains	Baseball hail, glass, crop	Watch 674 expired	Just-hit / aftermath
SW Missouri / Illinois / SW Ohio	Trees, lines, isolated structural	LSRs overnight	Just-hit
SE Ohio / north-central WV	Trees, flash flood leftover	Overnight FFWs expired or expiring	Aftermath / check county
Atlantic vs. U.S. mainland	Fay near the Azores; no U.S. formation	NHC TWO	Quiet on the mainland

What this means for restoration teams

Fifty to sixty miles an hour is roof, siding, gutter, and tree-on-structure work. Last night’s Colorado hail is a glass and roof-inspection desk in a handful of High Plains counties, not a regional CAT. Ohio and West Virginia water from overnight flash-flood warnings is extraction and a 24–48 hour mold clock where water entered. Do not staff today’s Marginal as if Watch 674 were still up.

Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same day if water is inside. Turn around, don’t drown on leftover high water in southeast Ohio and north-central West Virginia.

What this is not

This is not a Slight Risk day, not a live watch, and not a U.S. mainland hurricane landfall. The work today, if it verifies, will be scattered: a wind swath through a Kentucky or West Virginia county, a hailer on the Caprock, leftover trees from Sunday night. That is the local-storm pattern this desk should staff.

Looking ahead

The next Day 1 outlook is scheduled by 1630 UTC. SPC Day 2 is also Marginal. Day 3 is currently no severe thunderstorms. Watch the afternoon Storm Tracker update rather than assuming this morning’s Marginal is the last line of the week.
