Flash Flood Warnings climbed back to 109 active alerts Saturday — reversing Friday’s brief retreat to 106 and resetting the event’s focal point on northwestern Louisiana and central Texas rather than the Texas-Oklahoma corridor and Gulf Coast that bore the brunt a day earlier.
The National Weather Service in Shreveport issued warnings spanning at least a dozen Louisiana parishes in two distinct clusters: a northwestern group covering Bienville, Bossier, Caddo, De Soto, Natchitoches, and Red River parishes, and a northeastern cluster encompassing Franklin, Jackson, Lincoln, Morehouse, Ouachita, Richland, Union, and West Carroll parishes. The breadth of Louisiana coverage signals a southward and eastward shift in the main moisture axis compared with Friday’s pattern.
In Texas, the National Weather Service in Corpus Christi placed central Duval County under a flash flood warning through 8:15 a.m. CDT, noting that Doppler radar confirmed 2 to 3 inches of rain had already fallen, with an additional 1 to 2 inches possible. Simultaneously, the Fort Worth office warned of flash flooding through 10:00 a.m. CDT across southern Freestone County, Leon County, east-central Limestone County, San Saba County, and Cherokee County in central Texas, with thunderstorms producing very heavy rain and numerous roads already reported flooded.
The 10-state footprint — Alabama, Florida, Illinois, Indiana, Kansas, Louisiana, Missouri, Mississippi, Nebraska, and Texas — has remained largely intact since Thursday’s peak of 122 alerts. The Saturday uptick from 106 to 109 suggests the event is sustaining itself rather than winding down, consistent with a persistent deep-moisture feed from the Gulf of Mexico supporting repeated heavy rainfall rounds along a slow-moving boundary.
The cumulative nature of the flooding is a compounding factor: soils across south-central Texas and Louisiana are already saturated from multiple days of rainfall, meaning even moderate additional totals can produce significant runoff and road flooding.
The National Weather Service urges residents across all affected areas to turn around and not attempt to cross flooded roads. Most flood deaths occur in vehicles, often on roads that appear passable. Residents are asked to report observed flooding to local emergency services.
