Record-setting rains in southeastern Wisconsin overnight Saturday to Sunday led to life-threatening flash flooding in Wauwatosa, Milwaukee and surrounding communities. The downpour prompted water rescues, damaged homes and businesses, and knocked out power for thousands.

The City of Milwaukee Department of Public Works said Sunday morning that crews “are working nonstop assessing damage and clearing flooded areas.”
