  • Storm Updates: Gulf Coast Slight Flood, Quiet Severe Pulse — Saturday, October 3, 2026 (Morning)

    This is the Saturday morning Storm Tracker desk for October 3, 2026. Overnight into this morning the organized severe window stayed closed. The Storm Prediction Center 1300 UTC Day 1 convective outlook, updated 8:16 a.m. CDT by Guyer and Dean and valid 1300 UTC Saturday through 1200 UTC Sunday, carries no severe thunderstorm areas. The summary line is short: severe thunderstorms are not expected across the U.S. through tonight.

    These are county- and ZIP-scale leftovers and a coastal water board, not a mainland hurricane landfall. The live restoration ticket this morning is rain already aimed at the central Gulf Coast and the lower Texas coast, not a new convective watch. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

    What is live this morning

    No convective watches are currently valid. SPC’s watch page, updated 12:35 UTC Saturday, lists none. The most recently issued watch is Severe Thunderstorm Watch 676, a Wednesday, September 30 product for west-central Texas. Nothing from Friday night carried into Saturday morning as a severe thunderstorm or tornado watch.

    SPC local storm reports for the 1200 UTC Friday through 1159 UTC Saturday window, and for the new Saturday convective day that opened at 1200 UTC, show no tornado, hail, or wind reports received. The overnight severe hit list is empty. Pre-dawn thunderstorms were ongoing across the Dakotas ahead of a cold front, but the Day 1 discussion keeps severe potential virtually nil even if a stronger gust occurs this afternoon.

    What is organized is water. The Weather Prediction Center Day 1 Excessive Rainfall Outlook, updated 0738 UTC Saturday and valid 12 UTC Saturday through 12 UTC Sunday, holds a Slight Risk of excessive rainfall for the central Gulf Coast and the lower Texas coast. Forecaster Wegman left the coastal Slight Risk in place and added a higher-end Slight Risk from New Orleans through much of the western Florida Panhandle, citing urban impacts and rainfall volume rather than a change in the underlying front.

    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 on Saturday. A 15 to 25 knot southerly flow at 850 mb supports numerous showers and thunderstorms moving into the central Gulf Coast today and tonight. Precipitable water is at or above 2.5 inches for many areas. Extensive cloud cover and the October sun should limit instability with any reasonable distance from the coast, so convection that hits the coast is not expected to travel far inland without significant weakening.

    The 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 WPC still flags widely scattered flash flooding where that volume lands on urban drainage, especially from New Orleans through the western Florida Panhandle. Mississippi and Alabama coastal counties sit in the same Slight Risk envelope.

    Cities and counties to watch: New Orleans, 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. Inland rows are a weaker pulse. The front that stretches from the Carolinas southwest toward the Texas coastal plain is the broader thunderstorm focus, but weak vertical shear and modest lapse rates should limit organized severe convection along and south of it.

    Restoration read: water first, and only where a warning or a measured street flood actually verifies. Stage extractors, air movers, and moisture meters for urban low spots, underpasses, 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. Photograph standing water only if the road is already closed and it is safe to be there.

    Hotspot 2 — Lower Texas coast

    The second Slight Risk remains along 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 the area included in that Slight Risk on the 0738 UTC update.

    Friday afternoon’s central Texas story is a different board. The prior desk held a Slight Risk of excessive rainfall on the I-35 corridor from Dallas–Fort Worth toward San Antonio, plus flood advisories in Comal, Guadalupe, and Hays counties and a flood watch that included coastal and inland Jackson County until early Friday evening. Those were time-limited products. They are not the Saturday morning Slight Risk. If a river or areal flood warning is still up in central or south-central Texas this morning, treat it as yesterday’s water still in the channel, not as a new convective watch.

    Restoration read: Brownsville and the lower Texas coast are the new water ticket if cells train against the coast. Central Texas and southwest Kansas remain aftermath boards from Thursday and Friday. Do not send the same crew to both stories without checking which county actually has a warning now.

    Northern Plains scatter, and what expired

    Progressive westerlies cover the northern half of the country through tonight, with a fairly substantial shortwave trough amplifying over the northern Plains and Upper Midwest. As the cold front shifts east, a modest increase in moisture, steepening lapse rates, and increasing lift support isolated thunderstorms, including the pre-dawn activity across the Dakotas. SPC allows that some stronger, convectively enhanced wind gusts could occur this afternoon. Severe potential is expected to remain virtually nil. There is no Marginal, Slight, Enhanced, Moderate, or High Risk on the Day 1 categorical map.

    Friday afternoon flash-flood warnings on the Georgia–Florida line, including Clinch and Echols counties in Georgia and Columbia County in Florida, were issued by National Weather Service Jacksonville with expiration times Friday evening. They are not a live Saturday morning warning. A separate river flood warning on the lower Fox River near New Munster, affecting Lake County, Illinois, and Kenosha County, Wisconsin, was continued Friday afternoon until Monday morning for minor flooding. That is a river-stage ticket, not a convective watch.

    Tropics — not a U.S. land desk

    National Hurricane Center Advisory 25 at 2:00 a.m. MST Saturday places Hurricane Rachel near 19.4°N, 111.8°W, about 270 miles south-southwest of the southern tip of Baja California, moving west at 5 mph, with maximum sustained winds of 90 mph and a minimum pressure of 969 mb. Rachel has weakened slightly and continues westward. There are no coastal watches or warnings in effect. A turn toward the west-northwest is expected today, with additional slow weakening. Swells will affect the coast of west-central Mexico and the Baja California Peninsula through the weekend and can produce life-threatening surf and rip currents. That is a marine hazard, not a U.S. landfall.

    Hurricane Nolo is a Central Pacific system, near 23.3°N, 170.4°W at 2:00 a.m. HST, moving west at 13 mph with winds of 110 mph. It is not a U.S. mainland threat. The Atlantic basin has no tropical cyclones this morning. The Gulf Coast rain is tied to a tropical wave and deep moisture, not to a named storm making landfall.

    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.

    Southwest Kansas and central Texas are still yesterday’s water if a flood statement is still valid. Friday’s flash-flood emergency language in Ford County and the I-35 flood advisories do not automatically roll into Saturday. Check the office product before a crew leaves the yard. The empty SPC report page means there is no new hail or tornado survey from overnight.

    Next check

    The next Day 1 convective outlook is scheduled by 1630 UTC. Day 3, valid Monday, also carries no severe thunderstorm areas, with the more robust low-level moisture staying on the Gulf Coast and winds aloft remaining weak. The afternoon desk should re-read the WPC Slight Risk and any new flood warnings on the central Gulf Coast before treating the morning polygon as still live.
