The multi-day flood emergency showed its first signs of easing Sunday, with the National Weather Service recording 40 active flood and flash flood alerts across 11 states — down from 56 alerts in 13 states 24 hours earlier — but river flooding persisted across the Ohio Valley, and warnings emerged for the first time along Alaska’s remote Yukon Delta Coast.
Ohio remained the epicenter of active river flooding. The Scioto River at Circleville was running at 17.0 feet Sunday, producing lowland flooding along Island Road and Canal Road near State Route 104 in Pickaway County, with a warning extended through Monday evening. The Little Miami River at Spring Valley stood at 12.0 feet, pushing water into low-lying areas near Spring Valley, Roxanna, and east of Waynesville across Greene and Warren counties. The Mad River near Springfield recorded 12.9 feet at 4:15 a.m. EDT Sunday — with flooding along Spangler Road and Lower Valley Pike in Clark County — though the National Weather Service forecast that river to fall below flood stage by Sunday afternoon.
Active warnings also covered portions of Alabama, Illinois, Indiana, Louisiana, Missouri, Mississippi, Pennsylvania, Texas, and Washington state. In Illinois, alerts extended to Clay and Richland counties. In Mississippi, Jackson County remained under warning. In Missouri, Cooper County was included in the active list.
The most significant geographic development was the addition of Alaska’s Yukon Delta Coast to the warning map — a remote coastal region absent from Saturday’s affected-state list — underscoring the wide and varied footprint of the current flood pattern.
At the same time, the drop from 56 to 40 alerts reflects genuine improvement in parts of the system. States present in earlier reports — Kentucky and West Virginia — no longer appear among the 11 currently affected, suggesting upstream rivers are receding.
Still, water moves slowly through large drainage basins. Warnings across four Ohio counties — Pickaway, Greene, Warren, and Clark — remained extended into the coming days, a reminder that river crests often lag well behind the rainfall events that trigger them. Road flooding is likely to persist in those areas even as upstream gauges trend downward.
The National Weather Service continued its standing safety guidance across all active warning zones: motorists must not attempt to cross flooded roads. The agency notes that most flood deaths occur in vehicles.
Residents tracking conditions downstream should consult local NWS forecasts; those in the Gulf Coast corridor — including Houston — and in Jackson, Mississippi should monitor area rivers as the broader drainage system works through elevated water levels over the coming days.
