This is the Saturday afternoon Storm Tracker desk for October 3, 2026. The organized severe window is still closed. The Storm Prediction Center 2000 UTC Day 1 convective outlook, updated 2:46 p.m. CDT by Thornton and valid 2000 UTC Saturday through 1200 UTC Sunday, carries no severe thunderstorm areas. The summary line is unchanged from the morning issuance: organized severe thunderstorms are not forecast through tonight. The 20z update made only minor adjustments to the general thunder line.
What is organized this afternoon is water, not wind or hail. Restoration exposure is coastal rain on the central Gulf Coast and the lower Texas coast, plus river stages already above flood stage in eastern Iowa. There is no convective watch, no mesoscale discussion, and no SPC local storm report on the board. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.
What is live this afternoon
No convective watches are currently valid. SPC’s watch page, updated 21:16 UTC Saturday, lists none. The most recently issued watch remains Severe Thunderstorm Watch 676. No mesoscale discussions are in effect as of 21:10 UTC; the most recently issued discussion is MD 2345. The national watches-and-warnings text summary does not show a live Severe Thunderstorm Warning or Tornado Warning this afternoon.
SPC local storm reports for the Saturday convective day, 1200 UTC Saturday through 1159 UTC Sunday, show no tornado, hail, or wind reports received as of this desk. The afternoon severe hit list is empty. Showers and low-topped thunderstorms over parts of the Dakotas are spreading into Minnesota. Surface dewpoints are generally in the 40s. A pocket of weak instability can support occasional lightning, and convectively enhanced wind gusts may occur as low-level lapse rates steepen, but SPC keeps the overall severe-wind risk low because instability is minimal.
The Weather Prediction Center Day 1 Excessive Rainfall Outlook, updated 0738 UTC Saturday and valid 12 UTC Saturday through 12 UTC Sunday, still holds a Slight Risk of excessive rainfall for the central Gulf Coast and the lower Texas coast. Forecaster Wegman left both coastal Slight Risk areas in place and kept a higher-end Slight Risk from New Orleans through much of the western Florida Panhandle, citing urban drainage and rainfall volume. There is no Marginal, Slight, Enhanced, Moderate, or High severe-risk area on the Day 1 categorical map.
Hotspot 1 — Central Gulf Coast
A tropical wave moving across the Gulf is funneling record to near-record atmospheric moisture into much of the Gulf Coast. A 15 to 25 knot southerly flow at 850 mb supports numerous showers and thunderstorms into the central Gulf Coast today and tonight. Precipitable water is at or above 2.5 inches for many areas. Cloud cover and the October sun should limit instability away from the coast, so cells that reach the shoreline are not expected to travel far inland without weakening. A weak mid- and upper-level wave centered over the Bay of Campeche is aiding the northward moisture push. SPC still expects this convection to stay disorganized, with weak low-level winds.
WPC’s coast can expect 3 to 6 inches of rain today, with locally higher amounts. Flash-flood guidance is high and soils have been dry, but the volume can still overcome that in urban drainage from New Orleans through the western Florida Panhandle. Mississippi and Alabama coastal counties sit in the same Slight Risk envelope. A nearly stationary front from south and coastal Texas into the Southeast and Carolinas remains the broader thunderstorm focus. Poor lapse rates aloft and weak deep-layer shear should limit organized severe storms along that front through tonight.
Cities and counties to watch: New Orleans and the south-shore and east-bank parishes, coastal Mississippi from Hancock through Jackson County, Mobile and Baldwin counties in Alabama, and the western Florida Panhandle from Pensacola toward Panama City. River products already on the board are not the same as a flash-flood warning. National Weather Service Mobile, issued by New Orleans, has a flood warning for the Styx River near Elsanor in Baldwin County for minor flooding from Sunday evening into Monday morning, with a forecast crest of 12.3 feet early Monday against a 12.0-foot flood stage. A separate flood warning covers the Shoal River near Crestview in Okaloosa County for minor flooding from Monday evening into Thursday morning, crest forecast 9.0 feet Tuesday against an 8.0-foot flood stage.
Restoration read: water first, and only where a warning or measured street flood verifies. Stage extractors and moisture meters for urban low spots and slab-on-grade first floors. This is not a wind or hail board. Do not staff a regional roof crew on a Slight Risk of excessive rainfall. The Styx and Shoal warnings are river-stage tickets for later tonight through early next week, not an afternoon structural-wind call.
Hotspot 2 — Lower Texas coast
The second Slight Risk remains on the coast of Deep South Texas. Onshore northeasterly flow of the same deep tropical moisture may reach urban areas such as Brownsville. Because this stretch of coast sits roughly perpendicular to the mean flow, WPC expects the onshore push to let convection move a few miles inland before it dissipates. No change was made to that Slight Risk area on the 0738 UTC update.
Friday’s central Texas excessive-rain story is a different board. Those time-limited products are not the Saturday Slight Risk. If a river or areal flood warning is still up in central or south-central Texas, treat it as yesterday’s water still in the channel.
Restoration read: Brownsville and the lower Texas coast are the new water ticket if cells train against the coast. Do not send the same crew to the Gulf Coast polygon and a leftover central Texas channel without checking which county has a warning now.
Hotspot 3 — Dakotas into Minnesota, and Iowa river stages
A shortwave trough in the northern mid-level westerlies continues east across the northern Plains and Upper Midwest. Showers and low-topped storms ongoing over parts of the Dakotas spread into Minnesota this afternoon. SPC allows a convectively enhanced gust as lapse rates steepen. The severe risk stays low. There is no watch and no storm report to hang a roof or tree crew on.
Eastern Iowa is the leftover water ticket. National Weather Service Quad Cities flood statements at 9:07 a.m. CDT Saturday keep a major flood warning on the Wapsipinicon River near De Witt 4S, affecting Clinton and Scott counties, until further notice. The stage was 12.9 feet at 8:30 a.m., flood stage is 11.0 feet, and impacts at 13.0 feet include residences along the river. The North Skunk River near Sigourney, Keokuk County, remains in a moderate flood warning until late Sunday night, stage 18.4 feet against a 16.0-foot flood stage, mostly agricultural land. The Skunk River at Augusta, affecting Lee, Henry, and Des Moines counties, remains in a minor flood warning until Sunday evening, stage 16.9 feet against a 15.0-foot flood stage.
Restoration read: the Wapsipinicon near De Witt is the residential river ticket if water is already in yards or first floors. The Skunk statements are mostly agricultural. Neither is a new convective watch, and neither produced an SPC wind or hail report today.
Just hit
The last 24 hours did not add a severe-report ticket. SPC’s Saturday report page has no tornado, hail, or wind reports. Friday night into Saturday morning did not leave a new hail or tornado survey on the filtered report page. The tickets already open are river stages: major flooding on the Wapsipinicon near De Witt, moderate flooding on the North Skunk near Sigourney, and minor flooding on the Skunk at Augusta. Gulf Coast river rises on the Styx and Shoal are forecast products for Sunday night into early next week, not claims already logged this afternoon.

What this means for restoration teams
There is no wind-driven roof board on the Day 1 outlook. A 3-to-6-inch coastal rain is wet drywall, flooring, and a 24-to-48-hour mold clock only where water actually enters. High flash-flood guidance and dry soils mean many miles of the Slight Risk will not produce a claim. Staff the warning, not the polygon. Urban New Orleans through the western Florida Panhandle is the higher-end piece of the same Slight Risk because of drainage, not because a watch is up.
Eastern Iowa is the only residential water ticket already on a river gauge this afternoon, and it is the Wapsipinicon near De Witt, not a statewide Iowa event. Southwest Kansas and central Texas remain yesterday’s water only if a flood statement is still valid. The empty SPC report page means there is no new hail, tree, or tornado survey from today.
What this is not
This is not a derecho, not a tornado outbreak, and not a U.S. hurricane landfall. Hurricane Rachel, Advisory information at 2:00 p.m. MST Saturday, is near 19.8°N, 112.5°W, about 270 miles southwest of the southern tip of Baja California, moving west-northwest at 5 mph, with maximum sustained winds of 80 mph. There are no coastal watches or warnings in effect. A slow west to west-northwest motion continues through the weekend, away from the U.S. mainland. Swells can affect west-central Mexico and the Baja California Peninsula. That is a marine hazard, not a U.S. land ticket. Hurricane warnings on the national summary this afternoon are offshore-waters products for the eastern Pacific within 250 nautical miles of Mexico, not U.S. coastal warnings.
Hurricane Nolo is a Central Pacific system accelerating west and expected to cross the International Date Line on Sunday. It is not a U.S. mainland threat. The Atlantic basin has no tropical cyclones. The Gulf Coast rain is tied to a tropical wave and deep moisture, not to a named storm making landfall.
Looking ahead
The Day 2 convective outlook, issued 12:16 p.m. CDT Saturday and valid 1200 UTC Sunday through 1200 UTC Monday, also carries no severe thunderstorm areas. Severe storms are not forecast for Sunday. An upper low over southern Canada is forecast to intensify as it crosses the northern and eastern Great Lakes, with a leading shortwave moving from the eastern Lakes into the Northeast and a portion of the cold front moving offshore. Scattered thunderstorms are expected ahead of the front and along sea-breeze boundaries, but very weak mid-level lapse rates and little deep-layer shear should keep organization minimal. A sporadic wet microburst is possible near and just offshore the southern Alabama and Florida coasts. Severe potential stays low. Shortwave ridging to the west supports stable conditions over much of the country, with isolated storms possible over a small part of central and southwest Colorado near the higher terrain.
