Storm Updates: Texas Coast Marginal Flood, Quiet Severe Pulse — Monday, October 5, 2026

This is the Monday afternoon Storm Tracker desk for October 5, 2026. The organized severe window is closed. The Storm Prediction Center 2000 UTC Day 1 convective outlook, updated 2:56 p.m. CDT by Thornton, kept the categorical map at no severe thunderstorm areas through tonight. The 1128 a.m. CDT discussion from Gleason and Chalmers still stands: locally gusty winds are possible with low-topped convection in New England, showers and thunderstorms linger along a slow front from the northern Gulf into southern Georgia and northern Florida, and isolated storms may continue from the Sierra into the Great Basin and the southern and central Rockies. Elevated storms are possible late this afternoon into tonight across parts of the Upper Midwest. Weak instability is the limiter in every one of those regions. Restoration exposure this afternoon is water, not a wind or hail outbreak: ponding on the lower Texas coast, a pulse-heavy rain band from the Florida Panhandle into eastern Georgia, and leftover river stages on the Mississippi.

What is live this afternoon

SPC current watches, updated 2:14 p.m. CDT Monday, list no watches valid. The most recent convective watch on the archive page is watch 0676. No mesoscale discussions are in effect as of the 2:33 p.m. CDT SPC update. Day 1 tornado, wind, and hail probabilistic areas are empty. Today’s SPC local storm report page for the 1200 UTC October 5 through 1159 UTC October 6 window shows no tornado, hail, or wind reports received as of this desk check.

The Weather Prediction Center Day 1 Excessive Rainfall Outlook, updated 11:55 a.m. EDT Monday and valid 16 UTC October 5 through 12 UTC October 6, is the product that still has a restoration ticket. WPC and the Brownsville office dropped the Slight risk on the southern lower Texas coast and replaced it with a small Marginal, mainly eastern Cameron County and coastal Willacy County, including Brownsville and South Padre Island. Heaviest rain had been on South Padre Island and the southern tip of Texas. Guidance keeps the best convergent area just offshore overnight, with a few cells able to sneak back onshore. Farther east, a Marginal remains over the Florida Panhandle, northern and central Florida, and eastern Georgia. The front was analyzed along the Florida-Georgia border at 12 UTC, expected to bisect northern Florida later this afternoon. Precipitable water on the 12 UTC Jacksonville sounding was 2.44 inches. Best 2-to-4-inch signature sits between Destin and the Big Bend and inland near and west of Tallahassee, including the Apalachicola National Forest and US 98 towns. Coastal I-95 from Savannah through Jacksonville to St. Augustine is the urban runoff strip.

The national watches-and-warnings text still carries early-morning flash flood warnings that have expired: Coffee and Dale counties in southeastern Alabama until 4:15 a.m. CDT, and northern Barbour County until 2:30 a.m. CDT, with 4 to 6 inches cited in Barbour. Those are last-night tickets, not live polygons. River flood warnings that still matter this afternoon include minor flooding on the Mississippi River at Louisiana, Missouri, in effect until Wednesday morning (stage 15.2 feet at 10 p.m. CDT Sunday, flood stage 15.0), and at Clarksville, Missouri, until Tuesday evening (stage 25.2 feet, flood stage 25.0). No severe thunderstorm warning or tornado warning was the lead product on the national summary at this check.

Hotspots

Lower Texas coast — Cameron and Willacy

Brownsville, South Padre Island, Port Isabel, and coastal Willacy are the tightest flood footprint this afternoon. WPC’s 16Z update, coordinated with the Brownsville office, cut the Slight to a Marginal after radar showed the heaviest rain on the island and the southern tip rather than a broad inland swath. Neighborhood probabilities for more than 3 inches stayed modest, and hourly chances of an inch or more drop after mid-afternoon as the convergent axis slides offshore. Restoration read: isolated street and low-spot water, not a multi-county extraction day. Crews already on a water ticket should finish the wet middle before calling this a new event.

Florida Panhandle into eastern Georgia

Destin, Panama City Beach, Apalachicola, Tallahassee, and the Apalachicola National Forest sit under the best remaining heavy-rain signature, with 2 to 4 inches possible before the ascent lifts out this afternoon. Sandy soils make the forest and US 98 towns hard to flood unless rates exceed about 3 inches an hour. Panama City Beach and Apalachicola proper are the exceptions WPC flagged. Farther east, Savannah, Jacksonville, and St. Augustine have the urban runoff problem: neighborhood probabilities for more than 5 inches of 40 to 60 percent along the Georgia-Florida coast, but low probabilities for a broad 2-inch footprint, which is the signature of pulse storms, not a training line. Restoration read: short windows of ponding on I-95 and poor-drainage lots. Tree and wind claims are not the organized threat. Effective bulk shear under 30 knots and poor lapse rates are why SPC left this out of every severe area.

New England gusts, and the Mississippi river stages

Northern New York into northern New England can still see low-topped showers and a locally gusty wind as the Quebec trough moves east. SPC’s morning and midday discussions both said limited low-level moisture should hinder an organized severe wind threat. That is a roof-and-limb check, not a watch. On the Mississippi, Louisiana and Clarksville remain in minor flood warnings into Tuesday and Wednesday. Edison Avenue past the railroad tracks at Louisiana, and the road to Port Marmac south of Clarksville, are the impact lines already written. Restoration read: access and contents at the river edge, not a convective outbreak.

Just hit

The last 24 hours did not produce a severe-report day. SPC’s filtered and unfiltered pages for today show no tornado, hail, or wind reports. Yesterday’s page, covering 1200 UTC October 3 through 1159 UTC October 4, also listed none. What did hit is water. Overnight flash flood warnings covered Enterprise, Ozark, Fort Rucker, Elba, and New Brockton in Coffee and Dale counties, and Clayton and the US 82 corridor in Barbour County, Alabama, with 1 to 3 inches already down in Coffee and Dale and 4 to 6 inches cited in Barbour before those polygons expired before dawn. A special marine warning early Monday noted a possible waterspout southeast of V Tower on Apalachee Bay. Those are already-ticket items if a call came in overnight. They are not an open warning this afternoon.

Pulse table

What this means for restoration teams

Do not staff a severe board tonight. There is no watch to stage against and no hail or wind report stack to work. The open work is water: finish overnight Alabama flood calls in Coffee, Dale, and Barbour if they are still wet; keep a small extract-and-dry crew available for Cameron County, Willacy County, and South Padre Island if a cell comes back onshore; and treat Panama City Beach, Apalachicola, Jacksonville, and the Savannah-to-St. Augustine strip as short-fuse ponding, not a line. Mississippi river access at Louisiana and Clarksville is a contents and road problem through midweek. Tree work in New England only if a local gust actually takes a limb. No client names belong on this desk.

What this is not

This is not a derecho, not a severe-thunderstorm outbreak, and not a U.S. landfalling hurricane. Hurricane Rachel, 90 mph and moving west at 8 mph near 20.3N 117.1W as of the 2 p.m. PDT advisory, is an eastern Pacific storm and is not a U.S. land threat. There are no tropical cyclones in the Atlantic. Invest AL92, a trough over the southwestern Gulf of America, has a 60 percent chance of formation in 48 hours and 80 percent in 7 days, with a tropical depression expected around midweek. NHC said it is too early to assign specific impacts to the northern Gulf Coast. It is not a named cyclone on or just off U.S. land this afternoon, so it does not open a named-storm restoration file today.

Looking ahead one day

The SPC 1730 UTC Day 2 outlook, issued 12:30 p.m. CDT Monday by Lyons and valid Tuesday, again has no severe thunderstorm areas. Severe storms are unlikely Tuesday. High pressure and cool northerly flow favor a drier, more stable East. Scattered storms remain possible on the Gulf Coast and into central and southern Florida as the front sags south, with weak lapse rates and shear. Isolated storms are possible over the higher terrain of the Rockies under a weak trough, and isolated storms are possible across the northern Great Lakes late Tuesday under cooler mid-level temperatures. The Gulf disturbance is the item to recheck Tuesday morning, not a reason to invent a landfall today.
