Flash flood warnings retreated to 70 active alerts Wednesday across 12 states — down from 94 Tuesday and 114 at Monday’s peak — but the narrowing count obscures a significant westward shift in the flood corridor, with Oklahoma now carrying the heaviest county-by-county exposure in the country.
The National Weather Service has placed more than 20 Oklahoma counties under active warnings, stretching from the western edge of the state — Harper, Woodward, Ellis, Major, Dewey, Alfalfa and Blaine counties — eastward through the Oklahoma City metro area, including Canadian, Oklahoma, Cleveland and Payne counties, and south to Carter, Bryan, Marshall and Johnston counties near the Texas line. The breadth of Oklahoma’s footprint Wednesday is the defining feature of this storm cycle’s latest chapter.
Arkansas remains heavily engaged. Warnings cover the southwestern tier of the state, including Hempstead, Lafayette, Little River, Miller, Nevada and Columbia counties, carrying over from Tuesday’s Ark-La-Tex activity. North Louisiana’s Claiborne, Lincoln and Webster parishes continue under alerts.
The most acute life-safety report overnight came from Haynesville, Louisiana, where local law enforcement confirmed multiple vehicles stalled in flood waters. The National Weather Service documented 3 to 7 inches of rainfall in the area; an additional 2 to 4 inches remain possible in the warned zone. Flash flooding is ongoing.
In northeast Texas, river flooding along the Sulphur River near Talco is forecast to persist through Friday afternoon at minor flood stage, affecting Morris, Red River, Titus, Franklin and Bowie counties. In Kansas, the National Weather Service in Dodge City issued a flash flood warning for southwestern Hodgeman County after Doppler radar confirmed 2 to 3 inches of rainfall by early Wednesday morning.
Wednesday’s 12-state footprint — Alabama, Arkansas, Florida, Illinois, Indiana, Kansas, Louisiana, Missouri, Mississippi, Oklahoma, Texas and Washington — marks a clear geographic rotation from Tuesday, when alerts were anchored along the Louisiana-Texas corridor and Virginia’s Tidewater coast. Virginia has exited the active warning map; Oklahoma and Kansas have expanded in.
Residents across warned areas should avoid all flooded roadways. The National Weather Service is emphatic: most flood deaths occur in vehicles. Turn around, don’t drown.
Local conditions for the two most active urban centers in the corridor: Oklahoma City weather and Shreveport weather.
