The National Weather Service had 36 active flood warnings in place Monday across 12 states — down from 40 the previous day but spanning one additional state — as persistent river flooding continued to affect communities from the Ohio Valley to the Southeast and along Alaska’s remote Yukon Delta.
Ohio remained the primary zone of concern. Sunday Creek in North Central Athens County and southeastern Perry County was still running above flood stage early Monday, with a National Weather Service warning in effect until 10:45 a.m. EDT. Flooding of rivers, creeks, streams and other low-lying areas was described as imminent or occurring across southeastern Ohio. Further west, Killbuck Creek near Killbuck remained in minor flood stage, with warnings extended through late Tuesday evening for Wayne and Holmes counties — a multi-day stretch that has come to define the broader event’s character. Athens, Ohio residents should continue monitoring local gauge reports through at least midweek.
Georgia’s Big Creek at GA 9 near Cumming remained under an extended flood warning Monday as minor flooding continued and was forecast to persist through the evening in Forsyth County. The National Weather Service noted that at 8 feet, floodwaters spread into the creek’s natural flood plain both upstream and downstream from the gauge. The Atlanta area — with Forsyth County sitting along the northern metro fringe — could see prolonged impacts if additional rainfall pushes gauge levels higher before the warning expires.
Monday’s 12-state warning footprint — Alaska, Alabama, Georgia, Illinois, Indiana, Louisiana, Mississippi, New Mexico, Ohio, Texas, Washington and West Virginia — is broader by one state than Sunday’s count, even as the total alert number declined. Alaska’s Yukon Delta Coast and Lower Yukon River, which first entered the warning map Sunday, remained active Monday.
The National Weather Service continued to urge motorists to avoid flooded roads, noting that most flood deaths occur in vehicles. Those near swollen waterways were advised to stay well back from unstable riverbanks.
With Killbuck Creek warnings locked in through at least Tuesday evening and multiple river gauges across the Ohio Valley still elevated, the multi-day flooding event appears likely to carry into midweek before the cumulative warning count falls substantially further.
