Flash flood warnings across the central and southern United States pulled back to 52 active alerts spanning 10 states Tuesday, down from Monday’s peak of 72 across 13 states — the first meaningful reduction in a multi-day flooding outbreak and a sign that the event’s geographic reach is contracting, even as significant threats persist.
The retreat is notable for where it happened: Iowa, Indiana, and South Dakota, which anchored the earliest stages of the outbreak, have largely cleared the active warning map, as have Arkansas and Georgia, which the National Weather Service added to the alert zone only Monday. Warnings now remain concentrated in Alabama, Kansas, Kentucky, Louisiana, Missouri, Oklahoma, Tennessee, Texas, Washington, and Wyoming.
Kansas has sharpened into one of the event’s most consequential fronts. The National Weather Service is tracking moderate flooding on the Smoky Hill River at Enterprise, with that flood warning extended through late Friday evening. At 21 feet, low-land agricultural flooding is occurring between Enterprise and the Junction City corridor; at 26 feet, the valley north of that stretch is also affected. More than 10 central and eastern Kansas counties — including Dickinson, Clay, Geary, Morris, Ottawa, Pottawatomie, Riley, Wabaunsee, Lincoln, Labette, and Neosho — fall within active alert zones.
Kentucky recorded some of the most intense overnight rainfall. The National Weather Service in Louisville issued flash flood warnings Tuesday morning for portions of Green, Hart, Taylor, Breckinridge, Grayson, and Hardin counties. Doppler radar and surface gauges confirmed 3 to 5 inches of rain — with locally higher totals — fell across parts of Grayson County by early morning. Flash flooding of small creeks and streams was ongoing at the 7 a.m. CDT issuance, with conditions expected to persist through mid-morning. Residents near Louisville should anticipate closures on low-lying roads.
Tennessee also remains active, with warnings covering western counties including Weakley, Henry, Carroll, Benton, Henderson, and Decatur. The threat there bears watching as the system tracks eastward through the day.
The National Weather Service warns that most flood deaths occur in vehicles. Motorists should not attempt to drive around barricades or cross flooded roadways, and are urged to use extra caution after dark when flood hazards are harder to see. Flooding should be reported to local law enforcement when it is safe to do so.
While the overall warning count is trending downward, river flood advisories on systems like the Smoky Hill are expected to remain active for several additional days as upstream runoff continues to drain through regional watersheds. National Weather Service offices across the affected region are expected to reassess conditions in Tuesday afternoon briefings.
