The National Weather Service has 71 active flood warnings in effect across nine states — Alaska, Illinois, Michigan, Missouri, New Mexico, New York, Texas, Washington, and Wisconsin — with the heaviest concentration of alerts centered on the upper Midwest.
Wisconsin is bearing the brunt of the current flooding event. Multiple river systems are running above flood stage, including the Crawfish River at Milford in Jefferson County and the Fox River at three separate gauging points: Princeton and Berlin in Green Lake County, and near New Munster along the Kenosha-Lake County line. The Fox River near New Munster is producing moderate flooding — a step above the minor flooding category — and that warning has no firm expiration, indicating forecasters expect elevated water levels to persist.
The Crawfish River at Milford is in minor flood stage, with impacts beginning at 8.0 feet, where the National Weather Service says agricultural land and lowland areas experience widespread inundation. That warning runs through Monday morning. The Fox River near Berlin is also in minor flood stage, with its warning extending through Tuesday evening — a multi-day event that will continue stressing low-lying areas along the corridor.
The breadth of the alert map — from Southeast Alaska to the Texas Gulf Coast to the Pacific Northwest — reflects a pattern of concurrent, unrelated flood triggers rather than a single storm system. River flooding in the Midwest is typically driven by a combination of recent rainfall and soil saturation from seasonal snowmelt, while flood events in states like New Mexico and Texas more often trace to intense, localized convective rainfall.
Residents in affected areas should treat any moving water with caution. The National Weather Service notes that just six inches of fast-moving floodwater can knock a person off their feet, and two feet of water is sufficient to float a standard passenger vehicle. Driving into water of unknown depth remains the leading cause of flood-related fatalities in the United States.
For those in the Houston metro — one of the regions under active monitoring in Texas — see the Houston weather page for local conditions and any updated alerts. In Wisconsin, conditions along the Fox River corridor will remain a concern through at least midweek.
