  • 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.

    What this means for restoration teams

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

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

    What this is not

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

    Looking ahead

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

  • Storm Updates: 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.

    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.

  • 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.

    What this means for restoration teams

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

    What this is not

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

    Looking ahead

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

  • Storm Updates: 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.

    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.

  • Storm Updates: Kansas–Missouri Flood Moderate, Plains–Midwest Marginal — Tuesday, September 15, 2026 (Morning)

    This is a live Tuesday morning snapshot of local storm-type events across the United States as of Tuesday, September 15, 2026. Overnight the organized wind corridor that ran northern Kansas, southern and eastern Nebraska, and western and central Iowa is the just-hit desk. This morning the Storm Prediction Center holds a Marginal Risk of severe thunderstorms from the south-central Plains into parts of the Midwest. The louder national product is flood: the Weather Prediction Center Day 1 Excessive Rainfall Outlook carries a Moderate Risk over portions of northeastern Kansas into northwest Missouri, with a high-end Slight wrapping the Kansas City metro and the I-70 corridor.

    These are county- and ZIP-scale thunderstorms and flash-flood cells, not a mainland hurricane landfall. Restoration exposure today is leftover wind damage from last night plus a new heavy-rain ticket on already-wet Kansas and Missouri ground. 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 watch is in effect. Tornado Watch 669, issued late Monday evening, expired at 0500 UTC Tuesday (midnight CDT). Severe Thunderstorm Watch 668 from Monday afternoon is also down. The 1300 UTC Day 1 Convective Outlook (issued 7:28 a.m. CDT) is Marginal only. SPC language: strong to locally severe thunderstorms may occur from the south-central Plains into parts of the Midwest this afternoon and evening, with at least isolated damaging wind gusts possible. A Slight upgrade was considered for eastern Kansas into Missouri if an organized cluster can form, but the 1300 UTC package left probabilities at Marginal.

    WPC’s 0800 UTC Day 1 Excessive Rainfall Outlook is the headline product. A Moderate Risk covers northeastern Kansas into northwest Missouri and clips the far southeast corner of Nebraska along the Missouri River. Guidance centers the heaviest totals just north of Topeka toward St. Joseph, with 2 to 3 inches areal-average and locally 3 to 5 inches possible. Kansas City and the I-70 corridor sit in a high-end Slight. A broader Slight Risk extends south along the cold front on the High Plains and northeast into Midwest counties that already took rain overnight. A separate Slight Risk remains over eastern Arizona and western New Mexico on monsoon-style cells.

    National Hurricane Center: there are no tropical cyclones in the Atlantic. Tropical Depression Fifteen-E and Tropical Depression Norbert are both well out in the Pacific and not a U.S. mainland landfall threat.

    Hotspot 1 — Northeastern Kansas into northwest Missouri (flood)

    This is today’s primary new ticket. WPC coordinated a Moderate Risk with the Topeka and Kansas City weather forecast offices after neighboring counties already saw localized flash flooding earlier in the event. Precipitable-water anomalies of +2 to +3 standard deviations and flash-flood guidance that is already lowered set up 1-inch-per-hour rates after late-afternoon initiation. Best window is late afternoon through tonight as a low-level jet reloads the boundary. Training west-southwest to east-northeast is the mode that fails streets, underpasses, and small creeks first.

    Cities and counties to watch: Topeka and the northeastern Kansas counties north of I-70; St. Joseph and neighboring northwest Missouri counties; the Kansas City metro as a high-end Slight, not the Moderate core; far southeast Nebraska along the river.

    Restoration read: water first. Extraction and drying on a 24-hour clock if cells train over the same ZIP that already took rain Monday night. Do not treat Kansas City as the Moderate core unless WPC or the local office upgrades it later today.

    Hotspot 2 — South-central Plains into the Midwest (Marginal wind)

    A surface cold front will slide slowly south-southeast across the central Plains and mid-Mississippi Valley through this evening and stall late. Dewpoints in the 60s to low 70s sit ahead of it from the southern High Plains to the southern Great Lakes. SPC expects storms to develop roughly 20–23Z along much of the front. Loosely organized clusters with damaging wind are the primary severe concern, more so where heating is stronger on the southern and central Plains. Isolated hail is possible if a marginal supercell can hold from eastern Kansas into Missouri. Population under the 5 percent wind contour includes Wichita, Kansas City, St. Louis, Indianapolis, and Chicago.

    Restoration read: isolated 60 mph-class gusts and trees on service drops, not a regional wind event. Stage in the counties that already have a Severe Thunderstorm Warning, not the entire Marginal contour.

    Hotspot 3 — Southwest scatter and leftover Iowa water

    WPC keeps a Slight Risk of excessive rainfall over eastern Arizona and the western half of New Mexico. Isolated 2 to 3 inch cores on terrain are possible. SPC does not have severe probabilities over the Four Corners this morning; gusty outflow and small hail remain possible but unorganized.

    Iowa is yesterday’s and last night’s water still in the channel. NWS Des Moines had a Flash Flood Warning into 9:00 a.m. CDT this morning for parts of Dallas, Madison, Adair, Cass, Audubon, and Guthrie counties after 1 to 3 inches already on the ground. That is extraction work already on the books, not a new watch.

    Just hit

    Preliminary Storm Prediction Center local storm reports from the 1200 UTC Monday to 1159 UTC Tuesday window show a long wind corridor and almost no hail. One landspout was reported near Arboles, Colorado. No tornado path damage is in the filtered LSR set as of this morning desk.

    Measured wind highlights overnight: 87 mph 3 NE Guide Rock, Webster County, Nebraska; 83 mph 3 SE Smith Center, Smith County, Kansas; 77 mph 4 NNW Amy, Lane County, Kansas; 76 mph 4 N Kendall, Hamilton County, Kansas, and again 2 NNW Beatrice, Gage County, Nebraska; 75 mph 5 ESE Elmwood, Cass County, Nebraska; 74 mph 4 SW McClelland, Pottawattamie County, Iowa; 73 mph 1 N Shelby, Shelby County, Iowa; 71 mph near Richfield, Morton County, Kansas. Tree and power-line damage reports came in from Cass and Lancaster counties in Nebraska, Clarinda and Ames in Iowa, plus scattered tree work in Hinds County, Mississippi, and a power pole down in Tucson, Arizona. That is Monday night’s wind ticket. Today’s new work, if it verifies, is flash flooding on the Kansas–Missouri Moderate Risk.

    What this means for restoration teams

    Last night’s 70–87 mph gusts are roof, siding, gutter, and tree-on-structure work in Webster and Smith counties, the Kansas High Plains, Gage and Cass in Nebraska, and Pottawattamie and Shelby in Iowa. Photograph in daylight if it is safe. Today’s new ticket is water on the Topeka–St. Joseph axis. Heavy rain on already-wet ground is wet drywall and a 24–48 hour mold clock. Iowa southwest counties that sat under the early-morning flash-flood warning are extraction first, not a new severe-wind desk.

    Do not staff the entire SPC Marginal contour as if it were yesterday’s Slight. Yesterday’s Slight verified as a wind line. Today’s organized threat is rainfall rate, not shear.

    What this is not

    This is not a regional derecho and not a U.S. mainland hurricane landfall. Watch 669 is expired. SPC left the Day 1 package at Marginal because an organized cluster is still too uncertain. The work today, if it comes, will be scattered: a flooded intersection north of Topeka or around St. Joseph, a wind swath in an eastern Kansas or Missouri county if a cluster does organize, leftover trees from last night’s Nebraska–Iowa line. That is the local-storm pattern this desk should staff.

    Looking ahead

    SPC Day 2 is Marginal again Wednesday morning near the Great Salt Lake / Salt Lake City vicinity for hail and wind on a shortwave. Day 3 is no severe. WPC will reissue the excessive-rainfall outlook later this morning; treat the Moderate contour as live until that update. The next Storm Tracker desk will catch any watch that fires on the Kansas–Missouri boundary this afternoon.

  • Storm Updates: Carolinas Slight Risk, Detroit Tornado Aftermath, Labor Day Weekend Outages — Saturday, September 5, 2026

    Storm Updates: Carolinas Slight Risk, Detroit Tornado Aftermath, Labor Day Weekend Outages — Saturday, September 5, 2026

    The Storm Prediction Center has a Slight Risk of severe thunderstorms this afternoon and evening across parts of the Carolinas into southeastern Virginia. Damaging wind is the primary hazard. Isolated hail is possible. Behind that corridor, restoration crews are still working the multi-day Midwest and Mid-Atlantic wind event that produced Detroit’s first confirmed city tornado since 1997 and left tens of thousands without power heading into Labor Day weekend.

    This is a live snapshot for Saturday, September 5, 2026, built from NOAA/NWS Storm Prediction Center products, National Weather Service watches and warnings, and public outage reports. Conditions change fast — always verify with the National Weather Service for your county or ZIP.

    Current hotspots

    Carolinas into southeastern Virginia — Slight Risk (damaging wind primary)

    SPC’s 2000 UTC Day 1 outlook holds a Slight Risk from parts of the Carolinas into southeastern Virginia. Severe Thunderstorm Watches #656 and #657 have been in effect into the evening for large parts of central and eastern North Carolina and portions of South Carolina. Warnings have already gone out on individual cells in the Charlotte region, the Triangle, Forsyth and Nash counties, and nearby South Carolina counties.

    Main threats: scattered damaging gusts (60 mph tagged on several warnings; locally higher possible) and isolated hail near 1 to 1.5 inches. Clusters are spreading east-southeast toward the coast this evening. Isolated redevelopment behind the main band cannot be ruled out.

    Cities and metros in the risk area: Charlotte, Raleigh, Durham, Greensboro, Winston-Salem, Norfolk / Virginia Beach / Chesapeake, and upstate South Carolina communities under Watch 656.

    Southeast Michigan — just hit (tornado + wind recovery)

    Multiple rounds of severe weather hit Southeast Michigan on September 2–3. NWS Detroit confirmed an EF-0 in Lincoln Park and an EF-2 on the east side of Detroit — the first confirmed tornado in the city since July 2, 1997. A brief EF-0 also occurred in Marysville (St. Clair County) on the 2nd. Widespread straight-line wind damage, downed trees and lines, and heavy rain followed.

    Peak outages in the metro ran into the hundreds of thousands earlier in the week. As of Saturday afternoon, tens of thousands remain without power in Michigan (DTE still reporting a large remaining outage total). Restoration of service is underway through the weekend.

    Ohio Valley to Mid-Atlantic — residual wind and flood damage

    The same multi-day pattern produced a long damage swath from Michigan through Ohio, Indiana, Kentucky, Pennsylvania, and into the Mid-Atlantic. Reports included 80+ mph winds (gusts near 99 mph were cited in the Gary, Indiana area), tornadoes, flash flooding, and tree-and-wire losses. Outage totals at the peak of the event exceeded 500,000 customers across the corridor. Saturday still shows elevated outages in Ohio, Pennsylvania, Virginia, and North Carolina on top of the new Carolina convection.

    Recent 24-hour damage reports include trees on homes and lines in Tennessee, North Carolina, Virginia, and Ohio counties — the tail of the same system now feeding the Carolina risk.

    Southwest — flash flood threat into Sunday

    Monsoon moisture continues to support a flash-flood threat across parts of Arizona and Utah, including terrain around Grand Canyon, Zion, and Bryce Canyon. Those parks already saw significant flash flooding in recent days. Sunday remains the day to watch for park visitors and desert-wash travel. This is not a classic wind/hail CAT pulse; it is short-duration runoff in burns scars, slot canyons, and dry washes.

    Tropics

    No Atlantic hurricane is currently threatening the U.S. mainland. The 2026 Atlantic season remains below normal through early September, with no landfalling tropical cyclone driving this weekend’s restoration load. Pacific moisture (including remnants associated with eastern Pacific systems) is a contributor to the Southwest rain threat, not a Gulf or East Coast landfall.

    What this means for restoration operators

    • Carolinas / SE Virginia today: Stage for wind, tree, and envelope failures plus isolated hail. Commercial roofs, storefront glazing, and wet interiors behind failed soffits are the first walk after dark.
    • Detroit / SE Michigan: Tornado and straight-line wind claims are already open. Photo roofs, HVAC, and contents before the next rain. Power-off buildings delay drying — treat standing interior water as a clock, not a wait-for-power problem.
    • Ohio–PA–VA swath: Tree/wire/water day. Wind-driven rain through failed envelope. Treat overland flash-flood water as Category 3 until you prove otherwise.
    • Southwest parks and desert metros Sunday: Rapid-onset wash and canyon flooding, not a wide hail swath. Board-up and water extraction on structures in low washes; do not send crews into active slot canyons.

    Sunday look

    The Slight Risk shifts south into parts of Georgia and South Carolina (Savannah, Columbia, Charleston, Augusta in the broader envelope). Flash flooding remains possible in the Southwest. Cooler air follows the front into the Northeast and Mid-Atlantic behind this weekend’s storms.
