The multi-day flooding emergency widened significantly overnight: while the National Weather Service’s active alert count held at 50, the affected footprint expanded from eight to 12 states as flash flood warnings pushed into Oklahoma, Kentucky, Ohio, Indiana, and West Virginia for the first time in this event.
Oklahoma’s arrival marks the sharpest new development. The National Weather Service in Tulsa issued a flash flood warning for Latimer County in southeastern Oklahoma, valid until 9:30 AM CDT Friday, after Doppler radar confirmed thunderstorms dropped between 1 and 4 inches of rain. Flash flooding was described as ongoing or imminent. Rogers, Tulsa, and Washington counties in northeastern Oklahoma were also under active alerts — a separate cluster driven by the same storm system sweeping the southern plains.
Kentucky showed the broadest single-state exposure in Friday’s count, with active warnings stretching across more than two dozen counties. Fayette, Jefferson, Boone, Kenton, Campbell, Franklin, Scott, Harrison, Bourbon, Nicholas, Owen, Grant, Pendleton, Bracken, Robertson, Mason, and Lewis counties were all listed — a sweep that reflects river systems swelling after days of upstream rainfall, with much of the runoff funneling toward the Ohio River along Kentucky’s northern border.
Ohio’s southern tier joined the map as well. The National Weather Service posted flood alerts for Ross, Hocking, Clermont, Brown, Highland, Adams, Pike, and Scioto counties. That corridor feeds directly into the Ohio River basin; residents in the Cincinnati weather area should monitor local stream gauges as upstream flows from Kentucky and West Virginia continue moving through.
In Mississippi, river flooding persisted along the Pearl River watershed. Minor flooding was ongoing on East Hobolochitto Creek near Caesar and West Hobolochitto Creek near McNeil, both in Pearl River County, with conditions forecast to continue through Sunday morning.
Illinois and Missouri — central to earlier coverage — remained inside the alert footprint, as did Louisiana and West Virginia. Washington state and Alaska each appeared in Friday’s count; those likely reflect separate, localized events rather than the storm system anchoring the central U.S. flooding.
The Tulsa weather forecast will be a key indicator of whether Oklahoma’s flash flood threat persists through the afternoon or lifts as storm cells push northeast.
The National Weather Service’s guidance is unchanged: turn around, do not drive through flooded roadways. Most flood deaths occur in vehicles, and motorists should not attempt to navigate around barricades or through water of unknown depth.
River-based flooding across the Ohio Valley and Gulf Coast-adjacent watersheds is not expected to recede meaningfully through the weekend. Smaller tributaries in Mississippi are forecast to remain above flood stage into at least Sunday.
