Davenport, Iowa – Heavy downpours and repeated rounds of thunderstorms threaten much of eastern Iowa, northwest Illinois, and northeast Missouri with flash flooding through Saturday evening, with roads and low-lying areas especially at risk.
According to the National Weather Service Quad Cities office, a Flood Watch remains in effect until 7 p.m. Saturday. Scattered storms are expected to develop this afternoon and persist overnight, producing rainfall rates near 2 inches per hour at times. Locations including Davenport, Iowa City, Moline, Burlington, Rock Island, Macomb, and surrounding communities could see dangerous rises in creeks and urban streets, especially where storms hit repeatedly.
The most vulnerable areas include city neighborhoods with poor drainage, rural roadways near creeks, and spots that have already seen heavy rain this summer. Residents are urged to avoid driving through flooded roads, secure outdoor property, and keep cell phones charged in case of power outages. Emergency managers in Johnson, Scott, Whiteside, Rock Island, Lee, and McDonough counties are advising caution, with the potential for flash flooding and rapid stream rises.
Rain will continue in scattered waves, with 2 to 4 inches possible where storms repeatedly track. Storms should taper late Saturday evening, but additional advisories may follow if rivers rise overnight.
Warnings remain in effect through Saturday evening. Stay tuned to local alerts for updates or new Flood Warnings.
