Storm Updates: Four Corners Flood — Oct 22 Morning

As of this Thursday morning desk, October 22, 2026 (approximately 9:12 PM PDT / 12:12 AM EDT October 23 / 0412Z October 23), the national picture centers on the Southwest and Four Corners. The Weather Prediction Center holds a Moderate Risk of excessive rainfall over portions of southwest Colorado, southern Utah and northwestern New Mexico. The Storm Prediction Center maintains a Slight Risk of severe thunderstorms from eastern Arizona into western New Mexico. Post-Tropical Cyclone Josephine continues moving away with no U.S. coastal watches or warnings.

Tropical: None · Severe: Slight · Flood: Moderate

What Changed

Compared with the October 21 afternoon desk (quiet-pulse-2026-10-21-afternoon) and the prior version of this morning desk: SPC Day 1 Convective Outlook (0100 UTC October 23 / 8:01 PM CDT Thursday, October 22, 2026, valid 230100Z–231200Z) continues a SLIGHT RISK of severe thunderstorms from eastern Arizona into western New Mexico. Scattered severe storms remain possible across the Southwest and Great Basin tonight, with the most intense cells expected across western New Mexico through the remainder of this evening. Large hail, damaging winds, and a tornado or two are possible. No upgrade beyond Slight.
WPC Day 1 Excessive Rainfall Outlook (updated 0042 UTC Friday October 23 / discussion 8:44 PM EDT Thursday, valid 01Z–12Z October 23) holds a MODERATE RISK over portions of southwest Colorado, southern Utah and northwestern New Mexico (expanded southward into NW NM). Additional 1–2 inches (locally higher) possible; flash flooding likely in terrain, burn scars and slot canyons. Surrounding Slight Risk remains.
NHC confirms Josephine has become a powerful extratropical low. No tropical storm or hurricane watch or warning is in effect on the U.S. coast or Gulf of America. The system is accelerating northeastward away from the United States. Eastern Pacific Tropical Storm Vance remains well south of Mexico with no U.S. land threat.
Severe Thunderstorm Warnings and a Severe Thunderstorm Watch have been in effect across portions of Arizona. Flash Flood Warnings remain active for sensitive areas including Apache County (Canyon de Chelly / Chinle Creek) and other Four Corners drainages. Flood Watches continue regionally.
Nothing material closed the severe or flood lanes. Moderate flood risk is the highest open categorical level on Day 1. Quiet Pulse remains closed. This morning desk is updated in place under the standard slug; afternoon companion already live under quiet-pulse-2026-10-22-afternoon.

Live Status

SPC Day 1 (0100Z October 23) lists a Slight Risk (Level 2 of 5) from eastern Arizona into western New Mexico and the Four Corners. Mid-level southerly flow remains strong on the eastern periphery of the upper trough. Ongoing convection is a mix of supercells and linear clusters shifting into western New Mexico and southern Colorado. Buoyancy supports robust storms into the evening (MLCAPE around 1000 J/kg in favored areas) with deep-layer shear of 50–60 kt. Primary hazards are large hail, damaging winds and a tornado or two, maximized from northwestern New Mexico northward toward southern Colorado where low-level flow is backed and terrain influences hodograph curvature. Marginal Risk covers broader portions of the Great Basin.

WPC Day 1 maintains the Moderate Risk (Level 3 of 4) over southwest Colorado (San Juan Mountains), southern Utah and northwestern New Mexico. Antecedent rainfall, upslope flow and training convection support elevated flash-flood potential. Hourly rates of 0.5–1+ inches are possible; additional 1–2 inches (locally higher) expected in the Moderate area. A broader Slight Risk covers additional Southwest terrain. Marginal Risk remains for parts of the interior Northwest and southeast Florida.

Hotspots

Four Corners (southwest Colorado, southern Utah, northwest New Mexico): Moderate excessive rainfall risk. Heavy rain cores on the San Juans and surrounding high terrain, plus southern Utah canyons and burn scars. Life-threatening flooding possible in slot canyons, dry washes and urban areas. Evacuation orders noted earlier in some southern Utah locations. Flash Flood Warnings verified in upstream Arizona basins.

Eastern and central Arizona into western New Mexico: Slight severe risk. Supercells and clusters producing large hail and damaging winds; tornado potential elevated where low-level shear and topography align. Phoenix metro and Mogollon Rim remain in or near the risk area. Flash flooding accompanies the convection.

Residual California and Great Basin: Isolated severe hail/wind and brief tornado potential under limited instability ahead of the upper low. Marginal excessive rainfall risk in places; main threat is terrain-driven runoff rather than widespread flooding.

Just-Hit

National Weather Service offices have issued multiple Severe Thunderstorm Warnings across Arizona (Flagstaff and Phoenix CWAs) for 60 mph winds and quarter-size hail. A Severe Thunderstorm Watch has been in effect for portions of northern and eastern Arizona. Flash Flood Warnings are active for Apache County (Canyon de Chelly / Chinle Creek) with considerable damage threat noted. Local storm reports continue to verify hail and wind within the Slight Risk area. Rapid runoff is occurring in sensitive basins including the Paria River and Oak Creek corridors.

Pulse Table

Lane	Status	Notes (as of ~9:12 PM PDT / 0412Z 23 Oct 2026)
Tropical	None	Josephine post-tropical, accelerating NE away. No U.S. coastal watches or warnings. No other named systems threatening U.S. land or Gulf. TS Vance far south of Mexico.
Severe	Slight	SPC Day 1 (0100Z Oct 23): Slight from eastern AZ into western NM and Four Corners. Large hail, damaging winds, few tornadoes. Prior Severe Thunderstorm Warnings and Watch in AZ. Marginal elsewhere.
Flood	Moderate	WPC Day 1 Moderate over SW CO, southern UT, NW NM. Flash Flood Warnings live in AZ. Slight Risk broader Southwest. Terrain, burn scars and canyons primary concern.

Rising Queries

Trends unreachable.

Restoration Read

Primary restoration drivers are large hail and damaging wind impacts to roofs, vehicles, windows and vegetation across eastern and central Arizona, plus flash-flood damage to roads, low-water crossings, homes in washes and infrastructure in the Four Corners Moderate area. Burn scars and slot canyons remain highly sensitive. No tropical wind or surge component on U.S. land. Water and hail remain the dominant ticket generators for the next 12–24 hours.

What This Is Not

This is not a tropical cyclone landfall, a High Risk excessive rainfall event, or an Enhanced or Moderate severe outlook. No hurricane or tropical storm warning is in effect for any U.S. coastline or the Gulf of America. The Moderate flood risk is geographically focused on the Four Corners high terrain rather than a broad river flood. Isolated severe reports are occurring, but coverage remains scattered.

Looking Ahead One Day

Friday: The upper low continues northeastward. SPC Day 2 maintains residual severe potential shifting eastward. WPC Day 2 carries the excessive rainfall threat into the southern and central High Plains. Josephine remains post-tropical and moves farther away. California and the Southwest see gradual drying behind the system, though residual runoff continues in saturated basins. No new tropical threat indicated for U.S. land.

Live Status

SPC Day 1 (0100Z October 23) lists a Slight Risk (Level 2 of 5) from eastern Arizona into western New Mexico. Mid-level southerly flow remains strong on the eastern periphery of the upper trough. Ongoing convection is a mix of supercells and linear clusters shifting into western New Mexico and southern Colorado. Buoyancy around 1000 J/kg supports robust storms into the evening, with favorable deep-layer shear (50–60 kt) for hail and severe gusts. A tornado or two remains possible, particularly from northwestern New Mexico northward toward southern Colorado where low-level flow is backed and terrain influences hodograph curvature. Farther north into the Great Basin, isolated strong to severe storms remain possible under more limited buoyancy, with damaging gusts the primary hazard. Marginal Risk covers broader portions of the region.

WPC Day 1 maintains the Moderate Risk (Level 3 of 4) over southwest Colorado (San Juan Mountains), southern Utah and northwestern New Mexico. Anomalous moisture, diffluent flow, and training convection continue to support flash flooding. The San Juans see the heaviest accumulations, with model consensus for 3–4 inches and localized higher. Broader Slight Risk covers additional Southwest and Four Corners areas. Marginal Risk remains for parts of the interior Northwest and southeast Florida.

Hotspots

Four Corners (southwest Colorado, southern Utah, northwest New Mexico): Moderate excessive rainfall risk. Heavy rain cores on the San Juans and surrounding high terrain, plus southern Utah canyons and burn scars. Flash Flood Warnings already verified in parts of Arizona that feed into the region. Life-threatening flooding possible in slot canyons, dry washes and urban areas. Evacuation orders noted earlier in some southern Utah locations.

Eastern Arizona into western New Mexico: Slight severe risk with active convection. Supercells and clusters producing large hail and damaging winds; tornado potential elevated where low-level shear and terrain align. Phoenix metro and Mogollon Rim remain influenced. Flash flooding accompanies the convection. Verifying reports of hail and wind continue.

Just-Hit

National Weather Service offices have issued multiple Severe Thunderstorm Warnings across Arizona (Flagstaff and Phoenix CWAs) for 60 mph winds and quarter-size hail. Tornado Warnings were issued this afternoon for portions of Apache and Navajo Counties, Arizona, and parts of New Mexico. Flash Flood Warnings remain active for Apache County (Canyon de Chelly / Chinle Creek) with considerable damage threat noted. Local storm reports continue to verify hail and wind within the Slight Risk area. Rapid runoff is occurring in sensitive basins including the Paria River and Oak Creek corridors. No confirmed tornado damage reports received so far today. No widespread major river flooding reported.

Storm Updates: Arizona–New Mexico Slight — Oct 23 Morning

Tropical: None · Severe: Slight · Flood: Moderate

What Changed

Compared with the October 21 afternoon desk pulse table (SPC Slight over much of Arizona into SE Nevada/SW Utah): the latest SPC Day 1 Convective Outlook (0100 UTC October 23 / 6:00 PM PDT October 22, 2026, valid 230100Z–231200Z, issued 0801 PM CDT) holds a SLIGHT RISK of severe thunderstorms from eastern Arizona into western New Mexico. Large hail, damaging winds, and a tornado or two remain possible into the evening. The axis has shifted eastward as the upper trough progresses.
Severe Thunderstorm Watches #691 and #692 issued earlier on October 22 for Arizona have expired (by 1700–1800 UTC). Overnight local storm reports and warnings verified large hail, damaging winds, and flash flooding across Arizona higher terrain, Phoenix metro approaches, and southern Utah canyons. No new convective watches are active as of this desk.
WPC Day 1 Excessive Rainfall Outlook (updated 1601 UTC October 22, valid 16Z Oct 22–12Z Oct 23) introduces a MODERATE RISK over portions of southwest Colorado and southern Utah, with a broad Slight risk remaining across the Southwest including Arizona and western New Mexico. This is an upgrade from the prior Slight-only footprint over the same region. Anomalous moisture and orographic enhancement drive the higher threat.
Subtropical Storm Josephine continues accelerating northeastward away from the United States, forecast to become a powerful extratropical cyclone. No tropical storm or hurricane watches or warnings are in effect on the U.S. coast or Gulf. Tropical Storm Vance remains well south of Mexico in the Eastern Pacific with no U.S. threat.
The restoration ticket remains driven by Arizona/New Mexico severe (hail and wind) plus the new Moderate flood risk over southern Utah and southwest Colorado. Quiet Pulse is closed.

Live Status

As of this Thursday evening / Friday morning desk, October 23, 2026 (approximately 6:16 PM PDT October 22 / 0116Z October 23), the SPC maintains a Slight risk (Level 2 of 5) from eastern Arizona into western New Mexico through the remainder of the evening. Moderate buoyancy (MLCAPE around 1000 J/kg) and strong deep-layer shear (effective bulk wind difference 50–60 kt) support a mix of supercells and linear clusters. Large hail and severe gusts are the primary hazards; a tornado or two is possible where low-level flow is backed near northwestern New Mexico and southern Colorado terrain. Isolated strong to severe storms continue farther north into the Great Basin with more limited buoyancy.

The flood lane has upgraded to Moderate. WPC Day 1 places a Moderate risk over southwest Colorado (San Juan Mountains) and southern Utah, where prior heavy rainfall has elevated hydrologic sensitivity. Storm totals of 3–4 inches (locally 5+) are forecast, with orographic enhancement and rates periodically reaching 0.5 inch per hour. A broad Slight risk covers the remainder of the Southwest, including Arizona and western New Mexico, where convective rates of 1–2 inches per hour remain possible with training cells. Marginal risks cover portions of central California and southeast Florida.

The tropical lane remains closed for U.S. land impact. Subtropical Storm Josephine is accelerating northeastward away from the Mid-Atlantic, expected to transition to a powerful extratropical cyclone. No coastal watches or warnings are in effect. See the Josephine 2026 storm hub.

Hotspots

Eastern Arizona into western New Mexico: Primary remaining severe threat this evening. Ongoing convection organized into supercells and clusters capable of large hail, damaging winds, and isolated tornadoes as the main band shifts eastward.

Southwest Colorado and southern Utah: Moderate excessive rainfall risk. San Juan Mountains and slot canyons/washes are the focus for significant flash flooding given prior rainfall and continued moisture plume.

Central Arizona and Phoenix metro approaches: Included in the Slight severe and Slight flood envelopes earlier in the day; residual risk for heavy rain and isolated strong storms as the axis moves east.

Just-Hit

Local storm reports and NWS warnings through October 22 document large hail (quarter to golf-ball size and larger), damaging wind gusts to 60+ mph, and flash flooding across Arizona counties including Navajo, Apache, Gila, Maricopa, and Pinal. Flash Flood Warnings have been active on Chinle Creek and Canyon de Chelly National Monument, with river gauges indicating life-threatening flooding in places. Severe Thunderstorm Warnings covered areas near Show Low, Globe, and Superior. Southern Utah canyons between Zion and Bryce saw flash flooding. No new major river flooding is reported beyond these local impacts, but the Moderate risk supports continued high runoff potential overnight into early October 23.

Pulse Table

Lane	Status	Notes (as of ~6:16 PM PDT Oct 22 / 0116Z Oct 23 2026)
Tropical	None	Subtropical Storm Josephine accelerating NE away from the U.S., transitioning to extratropical. No coastal watches or warnings. TS Vance far south of Mexico.
Severe	Slight	SPC Day 1 (0100Z Oct 23): Slight from eastern AZ into western NM for large hail, damaging winds, isolated tornado. Prior watches expired. Marginal farther north into Great Basin.
Flood	Moderate	WPC Day 1 Moderate over SW Colorado and southern Utah; Slight across Southwest including AZ/western NM. Orographic 3–5″ totals possible in San Juans. Prior Flash Flood Warnings verified.

Restoration Read

Dominant ticket is Arizona/New Mexico severe (Slight risk with verified hail and wind damage from prior rounds) plus the upgraded Moderate flood risk over southern Utah and southwest Colorado. Phoenix metro and central Arizona face residual heavy rain and isolated strong storms as the axis shifts east. Monitor official sources for active Flash Flood and Severe Thunderstorm Warnings. The October 21 afternoon desk is linked under Sources.

What This Is Not

This is not an official forecast or warning. It is a desk summary of public products from the SPC, WPC, NWS, and NHC. A Moderate excessive rainfall risk is in effect over portions of southwest Colorado and southern Utah; Slight severe risk covers eastern Arizona into western New Mexico. No U.S. tropical watches or warnings are active.

Looking Ahead

Friday: SPC Day 2 carries a Marginal risk. WPC Day 2 continues excessive rainfall potential over portions of the West as the trough progresses. Josephine continues as a powerful extratropical system well offshore. The primary severe and flood axes continue shifting eastward overnight into early Friday, with decreasing coverage as buoyancy wanes.

Tropical: None · Severe: Marginal · Flood: Marginal

What Changed

Compared with this morning’s quiet-pulse-2026-10-19-morning pulse table: SPC Day 1 Convective Outlook (latest 0100 UTC / 7:52 PM CDT Monday, October 19, 2026, valid 200100Z–201200Z) holds the Marginal Risk of severe thunderstorms across parts of southeast Arizona and southwest New Mexico. Isolated severe gusts and hail remain possible this evening under 1000–1500 J/kg SBCAPE and ~40 kt shear. No upgrade to Slight or higher. No convective watches issued.
WPC Day 1 Excessive Rainfall Outlook (updated 0051 UTC Tuesday, October 20, 2026 / ~8:51 PM EDT Monday, valid 01Z–12Z Oct 20) confirms a Marginal Risk of excessive rainfall for portions of the Southwest (southeast Arizona and southwest New Mexico). Hourly rates of 0.5–1 inch possible in stronger cells, mainly urban and terrain-sensitive areas. Matches the morning desk; no Moderate or higher.
SPC today’s local storm reports (as of the 1200 UTC–1159 UTC page) include 1.25-inch hail 18 N Pirtleville, Cochise County, AZ (2157 UTC), 1.25-inch hail 1 W Deming, Luna County, NM (0010 UTC), downed power lines 5 N Rodeo, Hidalgo County, NM (2235 UTC), and a 77 mph gust 3 NNE Rodeo (2240 UTC). Isolated activity has verified in the Marginal area.
No tropical storm or hurricane watch or warning on the U.S. coast or Gulf of America. NHC Atlantic Tropical Weather Outlook continues to monitor AL93, a storm-force non-tropical low a few hundred miles off the southeast coast, with low near-term chance of subtropical development. High winds, coastal flooding, and dangerous surf persist along portions of the East Coast. Eastern Pacific Tropical Storm Trudy remains offshore Mexico only and does not threaten the United States. Nothing material moved on the tropical lane.
Nothing material has moved to open a Slight or higher severe lane or Moderate or higher flood lane. The Marginal severe window is expected to close with loss of heating overnight.

Live Status

As of this Monday afternoon desk update, October 19, 2026 (approximately 8:14 PM PDT / 11:14 PM EDT / 0314Z October 20), the national picture remains a Quiet Pulse. The only open severe lane is the small Marginal Risk over southeast Arizona and southwest New Mexico, where scattered thunderstorms have produced isolated large hail and strong wind gusts this evening. Activity is expected to weaken overnight. No Slight Risk, no watches.

Flood lane carries a Marginal Risk of excessive rainfall over the same Southwest corridor. Isolated flash flooding is possible this evening in urban areas, burn scars, box canyons, and dry washes, but coverage is limited. Residual river Flood Warnings continue, including moderate stage on the St. Johns River near Astor, Florida. Coastal Flood Warnings, High Surf Advisories, and marine Storm/Gale products remain active along portions of the East Coast in association with the offshore non-tropical low. These are coastal and marine, not inland flash-flood events of Moderate or higher intensity.

No named tropical cyclone threatens or has just hit U.S. land. The Atlantic basin has no tropical cyclones. AL93 may briefly acquire subtropical characteristics later this week but is expected to move northeastward away from the coast. Pacific Tropical Storm Trudy is offshore Mexico only.

Hotspots

Southeast Arizona / Southwest New Mexico: Marginal severe and excessive rainfall risk this evening. Isolated 1.25-inch hail and wind damage (downed lines, 77 mph gust) already reported. Cells moving quickly enough to limit widespread flooding but capable of localized issues on burn scars and in urban/terrain areas.

East Coast coastal waters and shoreline: Storm-force non-tropical low (AL93) driving high winds, very rough seas, coastal flooding, and dangerous surf from the Southeast through the Mid-Atlantic and Northeast. Marine Storm and Gale Warnings in effect. Not an inland severe or flash-flood event.

Alaska: Multiple Winter Storm Warnings for heavy snow (5–10 inches in valleys, up to 24–36 inches at higher elevations in the Eastern Alaska Range) with gusty winds. Travel impacts possible through mid-week. Outside the CONUS focus but active.

Just-Hit

SPC local storm reports for the current period document 1.25-inch hail near Pirtleville, AZ, and Deming, NM, plus wind damage and a 77 mph gust near Rodeo, NM, all within the Marginal Risk area this evening. No tornado reports. No widespread flash-flood reports noted beyond residual river stages.

Restoration Read

Quiet Pulse overall. The isolated Marginal severe and excessive rainfall potential in southeast Arizona and southwest New Mexico has produced localized hail and wind reports this evening, with possible limited claims, but coverage is small, no watches support a broader response, and the window is closing overnight. Coastal flooding, high surf, and beach erosion along the East Coast warrant monitoring for overwash and access issues, but these are not inland restoration events. Residual river flooding remains minor and stable. Standard quiet-day posture applies. No widespread severe or higher-end flash flood event is underway. Looking ahead, Pacific moisture is expected to increase flood and isolated severe potential over the Southwest mid-week.

What This Is Not

This is a Quiet Pulse. No SPC Slight or higher severe risk, no WPC Moderate or higher excessive rainfall, and no tropical storm or hurricane watch or warning on the U.S. coast or Gulf.

Looking Ahead One Day

Tuesday holds no widespread severe threat on current guidance. The Marginal Risk area in the Southwest is expected to diminish overnight. The non-tropical low continues to influence East Coast winds, surf, and coastal flooding into mid-week. No near-term tropical development expected for the U.S. coast or Gulf. Moisture from the Pacific system may begin increasing rain chances later in the week.

The isolated Marginal severe and excessive rainfall potential in southeast Arizona and southwest New Mexico may produce localized hail, wind, or flash-flood claims this evening, but coverage is limited, no watches support a broader response, and the window is closing with nighttime cooling. Coastal flooding, high surf, and beach erosion along the East Coast (particularly Outer Banks into the Mid-Atlantic) warrant monitoring for overwash and access issues, but these are not inland restoration events. Residual river flooding remains minor and stable. Standard quiet-day posture applies. No widespread severe or higher-end flash flood event is underway. Looking ahead, moisture from Pacific Tropical Storm Trudy is expected to increase flood and isolated severe potential over the Southwest mid-week.

What This Is Not

This is a Quiet Pulse. No SPC Slight or higher severe risk, no WPC Moderate or higher excessive rainfall, and no tropical storm or hurricane watch or warning on the U.S. coast or Gulf.

Storm Updates: Southern Plains Slight Risk, Kansas Tornado Window — Wednesday, September 30, 2026 (Morning)

This is a live Wednesday morning snapshot of U.S. local-storm activity as of Wednesday, September 30, 2026. The organized desk is back on the Plains. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook holds a Slight Risk of severe thunderstorms across portions of the southern and central Plains. No convective watches are currently valid. The Weather Prediction Center holds Moderate Risks of excessive rainfall across portions of the central and southern Plains and the Corn Belt.

These are county- and ZIP-scale thunderstorms and flash-flood corridors, not a U.S. mainland hurricane landfall. The National Hurricane Center’s last advisory on Polo said the remnants dissipated over northwestern Mexico. Restoration exposure today is wind-driven roof and tree work on the southern Plains this afternoon and evening, a conditional tornado window on the Kansas warm front, and interior water where cells train on already-wet ground. 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 outlook (issued 7:57 a.m. CDT, valid 1300 UTC Wednesday through 1200 UTC Thursday) upgrades Day 1 to a Slight Risk over about 82,000 square miles covering parts of southwest Oklahoma, northwest Texas, the Edwards Plateau, and a separate corridor through central and eastern Kansas into far southeast Nebraska. A broader Marginal wraps Fort Worth, Oklahoma City, Wichita, Norman, and Midland. Forecasters Guyer and Bentley: thunderstorms capable of severe wind gusts, some hail, and a brief tornado are expected across the southern Plains this afternoon into tonight. A few tornadoes and localized wind damage are also possible across Kansas and possibly far southeast Nebraska.

No Storm Prediction Center convective watches are currently valid. The watch page last listed Watch 674 as the most recently issued product; that watch is not today’s product and is not in effect this morning. Any new watch this afternoon would be a new number. Today’s SPC local-storm-report board (1200 UTC Wednesday through 1159 UTC Thursday) is empty as of this desk. That is expected before the diurnal window.

WPC’s Day 1 Excessive Rainfall Outlook (updated 0800 UTC Wednesday, valid 12Z Wednesday–12Z Thursday) keeps Moderate Risk language on two corridors: the Front Range into the southern Plains, and the central Plains into the Corn Belt. HREF neighborhood probabilities for more than 3 inches run 60–90 percent from the Lower Trans Pecos to the central Red River Valley, with a 2–4 inch, locally 6 inch footprint from northern Kansas toward Omaha and Des Moines south of I-80.

Overnight into this morning

Tuesday night’s 12Z-to-12Z LSR board is the just-hit file. Two tornado reports came in from the Texas Panhandle after midnight UTC: a social-media video tornado 3 miles south-southeast of Claude in Armstrong County at 0012 UTC (7:12 p.m. CDT Tuesday), position estimated via radar by NWS Amarillo; and a tornado 7 miles west-northwest of Timbercreek Canyon in Randall County at 0245 UTC (9:45 p.m. CDT), reported south of State Highway 335 west of I-27, on the ground 3–4 minutes and then roped out. Those are preliminary reports, not damage surveys.

Severe wind also verified on the same night: 67 mph at Roswell Air Center (KROW) in Chaves County, New Mexico, at 0033 UTC; 60 mph 2 miles northeast of Roswell at 0037 UTC; and 65 mph 6 miles west-northwest of Denver City in Yoakum County, Texas, at 0324 UTC, with additional measured gusts near 59 mph around 10:22 p.m. CDT. No hail reports were logged on that board. Tuesday afternoon’s Storm Tracker already had the Southwest flood-and-Marginal frame; last night added the Panhandle tornado and New Mexico/west Texas wind tickets.

Hotspot 1 — Southwest Oklahoma, northwest Texas, Edwards Plateau

This is the higher-confidence diurnal severe corridor. SPC expects early-day convection across the southern Plains to weaken or shift north by early afternoon, then redevelop late afternoon into evening ahead of the approaching mid/upper-level low. Heating of a very moist airmass should push MLCAPE near or above 1,500 J/kg from southwest Oklahoma into northwest Texas and the Edwards Plateau despite poor mid-level lapse rates. Supercells are possible at first. Front-parallel flow and increasing coverage favor a more linear mode with time. Strong to severe gusts are the most likely hazard. Isolated hail is more plausible across southwest Texas. A localized brief tornado threat can increase in the evening as effective storm-relative helicity rises in the moist environment.

Cities and counties to watch: Lawton, Wichita Falls, Abilene, San Angelo, Midland on the Marginal fringe, and the Edwards Plateau counties that sit under the Slight contour. An isolated severe threat could linger into parts of central Texas and Oklahoma overnight before buoyancy collapses east of the front.

Restoration read: wind first, water second. Stage tarps, generators, and tree crews before the late-afternoon initiation, not after the first warning. If a line trains on already-wet ground, treat the same ZIP as a water job by morning.

Hotspot 2 — Central and eastern Kansas into far southeast Nebraska

SPC upgraded this corridor on the 1300 UTC package. A rather strong low-level jet (50-plus knots diurnally) is forecast to shift northeast across central and eastern Kansas into western Missouri and southeast Nebraska or southwest Iowa by evening. Destabilization near the warm front may stay weak because of clouds, ongoing rain, and poor mid-level lapse rates. The upgrade is about 0–1 km and 0–3 km wind profiles that stay supercell-conducive even if CAPE stays muted. Multiple tornadoes are treated as a viable possibility, not a high-confidence outbreak.

Cities to watch: Topeka under the Slight population list; Wichita under the Marginal wrap; the I-70 and Kansas River counties; the Nebraska state-line counties toward Omaha. Flood Watch language was already in play overnight for parts of north-central and northeast Kansas through Thursday afternoon, with 2–4 inches widespread and locally around 6 inches in the wetter cores.

Restoration read: this is the tornado-and-water overlap. A brief tornado is a narrow swath — staff it as a local damage survey. Training rain on the same warm front is wet drywall and a 24–48 hour mold clock. Do not send the same crew to a wind ticket and a flooded basement without checking which county actually has a warning now.

Hotspot 3 — Southern Rockies, Front Range, and the Corn Belt flood overlay

WPC keeps a Moderate flood risk from the Sangre de Cristos and San Juan Range into the Front Range as northeasterly upslope persists on the northwest side of the surface low. Antecedent wet soils raise the flash-flood probability. Additional 2–4 inches, locally higher, is the working range, with two heavy periods: morning and again in the evening as the surface low intensifies.

Farther northeast, the Corn Belt Moderate sits on a southwest-to-northeast axis from northern Kansas through Omaha into Des Moines, generally south of I-80. Hourly rates of 1–2 inches in the better cores, with some repeating action on the warm front. North of the warm front the rates drop and the flash-flood signal cuts off. That is urban streets, low-water crossings, and small streams first — then finished basements if the same cell trains twice.

Just hit

Claude and Randall County, Texas, tornado reports and the Roswell / Denver City wind gusts are last night’s tickets. They sit under yesterday’s Marginal from southern and eastern New Mexico into west Texas. Today’s new work, if it verifies, is farther east and north: the southwest Oklahoma–northwest Texas–Edwards Plateau wind corridor, the Kansas warm-front tornado window, and the Moderate flood footprints on the southern Plains and the Kansas–Nebraska–Iowa axis.

Polo is not a U.S. landfall desk this morning. NHC’s last forecast/advisory (number 38, 0300 UTC Wednesday) placed the remnants near 30.5°N 108.0°W over northwestern Mexico and forecast dissipation by 12Z Wednesday. Hanna is an open-Atlantic tropical storm well east of the mainland. Neither is a restoration staffing problem for the CONUS this morning.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
SW OK / NW TX / Edwards Plateau	Severe wind, isolated hail, brief tornado	SPC Slight	Afternoon–tonight initiation
Central/eastern KS into SE NE	A few tornadoes, localized wind, training rain	SPC Slight + WPC Moderate flood	Conditional; no watch yet
Red River Valley / west-central TX	Flash flood, merging clusters	WPC Moderate	Late afternoon into Thursday morning
KS–Omaha–Des Moines (south of I-80)	Flash flood, 1–2 in/hr cores	WPC Moderate	Afternoon through overnight
Southern Rockies / Front Range	Upslope heavy rain, flash flood	WPC Moderate	Morning and evening pulses
TX Panhandle / Chaves County NM	Tornado and wind LSRs from Tuesday night	Yesterday’s Marginal	Just-hit / survey
Atlantic / East Pacific vs. U.S. mainland	No landfalling hurricane	Polo dissipated over NW Mexico	Quiet on the mainland coast

What this means for restoration teams

A Slight Risk is not a watch and not a warning. It is the afternoon and evening probability field. Wind at severe criteria is roof, siding, gutter, and tree-on-structure work. A brief tornado, if one occurs in Kansas or on the Edwards Plateau, is a narrow swath. Heavy rain on the two Moderate flood corridors is extraction the same night and a mold clock by Friday.

For teams in southwest Oklahoma, northwest Texas, and the Kansas warm-front counties: stage before mid-afternoon local, not after the first Severe Thunderstorm Warning. 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. Turn around, don’t drown on the Front Range and Corn Belt crossings.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Polo is gone over northwestern Mexico. Hanna is in the central Atlantic. The work today, if it comes, will be scattered: a wind swath through a Texas or Oklahoma county, a brief tornado on the Kansas warm front, a flooded intersection where cells train on the Red River or south of I-80. That is the local-storm pattern this desk should staff.

Looking ahead

The next Day 1 outlook is scheduled by 1630 UTC. Day 2 on the SPC page is already a Marginal. Watches, if they come, will most likely fire late afternoon on the southern Plains and early evening on the Kansas warm front. Watch the next Storm Tracker update rather than assuming this morning’s empty watch list is the last line of the day.

September 30, 2026

Storm Updates: Southwest Flood Moderate, West Texas Marginal — Tuesday, September 29, 2026 (Morning)

This is a live Tuesday morning snapshot of local storm-type events across the United States as of Tuesday, September 29, 2026. Water still owns the Southwest. The Weather Prediction Center holds a Moderate Risk of excessive rainfall over portions of the Four Corners country, after overnight flash-flood warnings from southwestern Utah and Mohave County, Arizona, through the Laughlin–Kingman corridor. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook draws a Marginal Risk of severe thunderstorms across southern Arizona and New Mexico into west Texas. No SPC watches or mesoscale discussions were in effect as of mid-morning UTC.

These are county- and ZIP-scale thunderstorms and flash-flood pulses, not a U.S. mainland hurricane landfall. Hurricane Polo is crossing the Gulf of California into Sonora and is forecast to weaken over the mountains of northern Mexico. Its mid-level remnant is the moisture and shear that keep the Southwest wet and give west Texas a localized tornado and damaging-gust window this afternoon and evening. Restoration exposure today is interior water on already-saturated soils, wash and burn-scar flooding, trees and service drops on isolated severe gusts, and a narrow tornado swath if a cell organizes over eastern New Mexico or the South Plains. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

No Severe Thunderstorm Watch or Tornado Watch is valid. Overnight Severe Thunderstorm Warnings on the northern Plains have expired. The live national products this morning are the SPC Marginal Risk from southeast Arizona through southern and eastern New Mexico into west Texas, and the WPC Day 1 Excessive Rainfall Outlook with a Moderate Risk still parked on the Southwest.

A mid/upper-level low and trough are moving across the Desert Southwest. Polo’s remnant mid-level circulation is expected to phase with that trough, helping a surface low consolidate over eastern New Mexico and west Texas tonight. Widespread convection is already ongoing on that moisture axis and is expected to continue through the afternoon and overnight. Poor mid-level lapse rates from the tropical remnant will cap how severe the storms get, but increasing deep-layer shear and a strengthening low-level jet later today leave room for organized linear segments and a few episodic supercells.

Hotspot 1 — Four Corners / Southwest flood pulse

This is the water desk. WPC language still supports a Moderate Risk of rainfall exceeding flash-flood guidance over parts of Arizona, southern Utah, New Mexico, and adjacent high country, with a predecessor rainfall event still working off tropical moisture. Antecedent soils are wet. Burn scars, slot canyons, and south- and west-facing slopes along the Mogollon Rim and the San Juans remain the first failures. Overnight Flash Flood Warnings covered Hildale and the Short Creek watershed in southwestern Utah, Colorado City and northern Mohave County, the Laughlin–Kingman–Bullhead City corridor, and pieces of San Bernardino and Clark counties. A separate overnight Flash Flood Warning hit the Fargo–Moorhead metro with up to two inches already down and additional rain possible.

Cities and counties to watch: Kingman, Bullhead City, Laughlin, Colorado City, Hildale, Flagstaff and Mogollon Rim drainages, the Lordsburg and Sacramento Mountains country in New Mexico, and saturated drainages in southern Utah. Fargo and Moorhead are yesterday-into-this-morning water, not the Moderate Risk core.

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

Hotspot 2 — Southeast Arizona through eastern New Mexico into west Texas

This is the SPC Marginal. Isolated severe gusts and possibly a tornado or two are the official Day 1 language for this afternoon into tonight from southern and eastern New Mexico into west Texas, with southeast Arizona included on the same corridor. Population centers inside the risk area include El Paso, Tucson, Lubbock, Amarillo, Midland, Odessa, and Roswell. Storm mode should trend complex or linear as coverage increases, with a few supercells possible when shear and the low-level jet increase later today.

NWS South Plains and Panhandle hazardous-weather outlooks this morning already flag multiple rounds of heavy showers and thunderstorms, flash-flood potential where cells train, wind gusts up to about 70 mph, and a brief tornado or two. Flood Watches are in play on parts of the southwestern Texas Panhandle and northwest South Plains.

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

Hotspot 3 — Northern Plains leftover and Dakotas flood slight

Monday evening’s Marginal Risk over the western and central Dakotas and central High Plains has expired. Preliminary SPC local storm reports from that window include a 77 mph gust near Kenel and a 71 mph gust near Pollock in Campbell County, South Dakota, plus 1.00-inch hail north of Belle Fourche. Those are just-hit wind and hail tickets, not a live watch.

WPC still carries a Slight Risk of excessive rainfall over portions of the eastern Dakotas into northwestern Minnesota, with a Marginal Risk from northern South Dakota through North Dakota and far northwest Minnesota. That is training showers on a southerly low-level jet, not a severe-watch corridor.

Just hit

Overnight and yesterday evening: flash flooding on the Arizona–Utah–Nevada border country and in the Fargo–Moorhead area; power lines down near New Kingman-Butler in Mohave County; severe gusts in Campbell County, South Dakota. Monday afternoon’s desk already had the Southwest water story in view. Today’s new work, if it verifies, is more Four Corners flooding plus the west Texas–eastern New Mexico Marginal window this afternoon and tonight.

Hurricane Polo is not a U.S. landfall. Tropical Storms Fay and Hanna are well out in the open Atlantic. Tropical Storm Rachel is offshore of southwestern Mexico. None of those systems is a mainland U.S. hurricane threat this morning.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
Four Corners / SW AZ–UT–NM	Flash flood, burn-scar and wash flooding	WPC Moderate excessive rainfall	Live flood pulse; overnight FFWs expired or rolling
SE Arizona / E New Mexico / west Texas	Damaging gusts, brief tornado possible, heavy rain	SPC Marginal	Afternoon–tonight window; no watch yet
SW Texas Panhandle / South Plains	Training rain, isolated severe	Flood Watch + local HWO	Today into tonight
Eastern Dakotas / NW Minnesota	Training heavy rain	WPC Slight / Marginal ERO	Showers; Fargo–Moorhead just-hit water
Western/central Dakotas (overnight)	Severe gusts, small hail	Expired Marginal + LSRs	Aftermath
Atlantic / Gulf vs. U.S. mainland	No landfalling hurricane	Polo weakening over Sonora	Quiet on the mainland coast

What this means for restoration teams

The Southwest Moderate Risk is wet drywall, silt in structures near washes, and a 24–48 hour mold clock on buildings that took water overnight. West Texas and eastern New Mexico are a wind-first desk if storms organize, with water on the same ZIPs if cells train. Dakotas gusts from last evening are already a roof-and-siding ticket in the counties that verified.

For teams near the SPC Marginal: stage before mid-afternoon local, not after the first warning. Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same night if water is inside. Turn around, don’t drown remains the flood rule on every wash in the Moderate Risk.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Polo is a Mexico landfall whose remnant moisture is already inside the Southwest forecast. The work today, if it comes, will be scattered: a flooded wash in Mohave or Washington County, a wind swath through a west Texas or eastern New Mexico county, leftover urban water in Fargo. That is the local-storm pattern this desk should staff.

Looking ahead

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

September 29, 2026

Storm Updates: Southwest Flood Moderate, Quiet Severe Pulse — Monday, September 28, 2026 (Morning)

Map of Arizona, southern Nevada, southwest Colorado, and western New Mexico marked for Monday's moderate flood risk — Monday morning desk. Moderate flood on the Southwest and Four Corners. Not an NWS warning.

This is a live Monday morning snapshot of U.S. local-storm activity as of Monday, September 28, 2026. Overnight into this morning, the organized severe desk stayed quiet. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook has no severe thunderstorm areas forecast. No convective watches are valid. The Weather Prediction Center holds a Moderate Risk of excessive rainfall over portions of the Southwest and Four Corners as tropical moisture associated with Hurricane Polo and remnants of Odalys lifts north into already wet ground.

These are county- and ZIP-scale thunderstorms and flash-flood pulses, not a U.S. mainland hurricane landfall. Polo is still a major hurricane approaching Baja California Sur and Sonora. Restoration exposure today is water first in the Southwest, then isolated wind and hail cleanup from last night’s High Plains and north Texas cells. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

SPC language at 0728 AM CDT: severe thunderstorm probability remains low on Monday. Isolated to scattered storms are still expected later over the northern High Plains from western Nebraska into the Dakotas, and numerous showers and thunderstorms are expected across southeast California, southern Nevada, and western Arizona. Those corridors do not carry unconditional severe probabilities on this outlook. The last issued convective watch was number 0674; nothing is live now.

WPC Day 1 excessive rainfall, issued 0812 UTC Monday and valid 12Z Monday through 12Z Tuesday, is the headline. A Moderate Risk covers portions of the Southwest and Four Corners. Guidance supports a widespread 1 to 3 inches across the region, with south- and west-facing slopes along the Mogollon Rim and the San Juans favored. Precipitable water is forecast 2 to 3.5 standard deviations above normal. Burn scars, rocky soils, and slot canyons locally raise the flood threat. The Moderate outline forks farther south in New Mexico toward the Lordsburg area and the Sacramento Mountains.

A weakening cyclone near the southern New England coast still supports showers and occasional embedded thunder along the coast. Instability is weak. That is leftover nor’easter weather, not a new severe corridor.

Hotspot 1 — Southwest and Four Corners flood Moderate

This is today’s organized desk. Moisture from Polo and post-tropical Odalys is being drawn north ahead of a mid-level trough moving from the California Valleys toward the lower Colorado River Valley. Widespread clouds and weak mid-level lapse rates should keep most storms disorganized, but rainfall rates on saturated soils do not need a supercell to fail a crossing.

Counties and terrain to watch: Mogollon Rim and higher terrain in Arizona; western and southwestern New Mexico including burn-scar drainages near Lordsburg; the San Juan Mountains and adjacent southwest Colorado; southern Nevada valleys that take runoff from steep slopes. WPC notes the Moderate continues into Tuesday over parts of the Southwest, central and southern Rockies, and southern High Plains.

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

Hotspot 2 — Northern High Plains isolated storms

SPC keeps general thunderstorms from western Nebraska north into North Dakota. A surface trough and modest 500–1500 J/kg CAPE later this afternoon could support isolated stronger cells. Uncertainty on location and intensity is why severe probabilities stayed off the map. A southerly low-level jet may keep elevated storms going tonight.

That is the same family that produced last night’s Cherry County hail. Staff it as isolated hail and outflow, not a watch day.

Hotspot 3 — Leftover Northeast coast and north Texas cleanup

The coastal cyclone continues to weaken near southern New England. Showers and occasional thunder remain possible near the coast. Sunday’s High Wind Warnings on the Jersey Shore and Long Island are already off the morning board from yesterday’s afternoon desk. Treat remaining coastal work as leftover water and beach debris, not a new wind outbreak.

North Texas had a short severe pulse last evening over Parker County. That is a just-hit ticket, not today’s outlook.

Just hit

SPC local storm reports for the 1200 UTC Sunday to 1159 UTC Monday window, all preliminary:

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

No tornado reports were received in that window. Severe Thunderstorm Warnings that fired Sunday evening over southwestern Cherry County, Nebraska, and northeastern Parker County, Texas, have expired.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
Southwest / Four Corners	Flash flood, training heavy rain, burn-scar runoff	WPC Moderate excessive rainfall	Live outlook through Tuesday 12Z
SE CA / southern NV / western AZ	Numerous showers and storms, isolated wet downburst	General thunder; no severe probs	Today into evening
Western NE into the Dakotas	Isolated strong storms, hail or gust possible	General thunder; no severe probs	Late afternoon–overnight
Cherry County, NE / Parker County, TX	Quarter hail, tree limbs	Expired SVR / LSRs	Just-hit cleanup
Southern New England coast	Showers, leftover coastal water	Weak cyclone; no severe area	Fading
Polo / Odalys	Mexico land and moisture feed, not CONUS landfall	NHC Polo major hurricane near Baja	Moisture into the Southwest

What this means for restoration teams

The national severe map is blank. That does not mean a quiet shop in Arizona, New Mexico, southwest Colorado, or southern Nevada. Moderate excessive-rainfall language on already wet soils is extraction, drying, and a 24–48 hour mold clock in finished space. Burn-scar fans fail first. Stage before the afternoon moisture surge, not after the first flash-flood warning.

Cherry County and Willow Park are yesterday’s hail and limb tickets. Photograph vehicles and roofs in daylight if it is still safe. Sully County’s 66 mph mesonet gust and the Sutton County 60 mph gust are isolated wind, not a line.

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

What this is not

This is not a Slight or Enhanced severe day and not a U.S. mainland hurricane landfall. Work today, if it verifies, is flash flooding on the Four Corners Moderate and isolated High Plains cells. That is the local-storm pattern this desk should staff.

Looking ahead

WPC keeps Moderate excessive-rainfall language into Tuesday over parts of the Southwest, central and southern Rockies, and southern High Plains, then into the southern Plains midweek. SPC’s next Day 1 update is scheduled by 1630 UTC. Watch the afternoon Storm Tracker rather than assuming the blank severe map lasts past sunset.

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

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

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

What is live this morning

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

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

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

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

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

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

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

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

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

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

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

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

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

Just hit

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

Pulse table

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

What this means for restoration teams

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

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

What this is not

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

Looking ahead

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

Storm Updates: 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.
