Quad Cities, Iowa – Thunderstorms capable of dumping several inches of rain in just hours are expected to strike late tonight, posing a flash flood risk across eastern Iowa and west-central Illinois, particularly south of Highway 30.
According to the National Weather Service in the Quad Cities, the most widespread rainfall is forecast between 11 p.m. Friday and 9 a.m. Saturday, with the highest flood risk centered over southeast Iowa and northeast Missouri. Cities including the Quad Cities, Peoria, and Kirksville could see localized flooding, especially in low-lying areas, near creeks, and in poorly drained neighborhoods.
The primary threat is torrential rainfall that may rapidly overwhelm roads, ditches, and basements. Motorists are urged to avoid travel overnight where water may cover roadways. Flash flooding is possible in areas that receive repeated storms during the event window.
Waterloo and Cedar Rapids are in a lower flood risk zone, but residents are still advised to remain weather-aware. South of Highway 30, the flood risk increases sharply, with Level 2 Flood Threat in portions of Missouri and Illinois, according to the flood index map.
Stay tuned to NOAA Weather Radio or local alerts for possible updates or flood warnings. Conditions may evolve quickly.
