Active flash flood warnings climbed to 125 Sunday across 13 states — up from 109 the previous day — as a moisture-laden storm system extended its reach northward into the Plains, adding Nebraska, Iowa, and the eastern Kansas corridor to an event that had been centered on Louisiana and central Texas a day earlier.
The National Weather Service now has warnings in effect across Alabama, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Nebraska, Oklahoma, Texas, and Washington, a geographic spread that has grown substantially since Saturday’s alert pattern.
Nebraska emerged as the event’s new focal point, with warnings covering an extensive band of counties stretching from the Platte River valley south through the Republican River watershed. Affected areas included Lancaster, Saunders, Seward, Saline, Gage, Johnson, Nemaha, Pawnee, Richardson, Adams, Clay, Fillmore, Franklin, Furnas, Gosper, Hall, Hamilton, Harlan, Howard, Kearney, Merrick, Nance, Nuckolls, Phelps, Polk, Sherman, Thayer, Valley, Webster, and York counties, among others. Iowa added a Missouri River border cluster — Fremont and Page counties — alongside a central grouping covering Boone, Platte, Colfax, Butler, Saunders, and surrounding counties.
In southeastern Texas, the National Weather Service in Lake Charles issued a flash flood warning for northeastern Jefferson County and southern Orange County through 10 a.m. CDT Sunday. Doppler radar showed thunderstorms had dropped between 2 and 4 inches of rain across the warned area by early morning, with additional accumulation of at least 1 inch forecast before the event cleared. Conditions remained dangerous along the Gulf Coast approach to Houston.
Kansas presented a split picture. The National Weather Service announced that a flood warning for Barton, Ellsworth, Rice, and Russell counties in central Kansas was set to expire at 7 a.m. CDT as heavy rain ended and local streams began stabilizing — though road closures remained in place. At the same time, warnings remained active across a wide swath of eastern Kansas including Shawnee, Douglas, Lyon, Geary, Riley, Pottawatomie, Jackson, Jefferson, Ottawa, Wabaunsee, Cloud, Clay, Republic, Marshall, Washington, Brown, Nemaha, Osage, Franklin, Coffey, and Anderson counties, where saturated ground and elevated stream levels sustained flood risk.
Mississippi’s Jones and Neshoba counties also appeared on warning rolls, carrying the event’s footprint into the Deep South.
In Lincoln, where Lancaster County sits under an active warning, residents were urged by the National Weather Service to stay off roads near low-lying areas and waterways. Across all warned regions, the agency repeated its standard directive: turn around, don’t drown — citing vehicles as the site of most flood-related fatalities.
With 125 concurrent warnings distributed across 13 states, the event has broadened significantly in its third day, though expiring alerts in parts of Kansas suggest the trailing edge of the system is beginning to allow some recovery even as the northern Plains absorb the heaviest current impacts.
