Heavy thunderstorms and gushing rain pummeled parts of the Midwest and Plains over the weekend, triggering flash flooding that caused water rescues and canceled multiple events in the Milwaukee area.

MILWAUKEE (AP) — The Milwaukee area began drying out Monday after weekend rain hit unofficial state records of more than 14 inches (36 centimeters) in less than 24 hours, leading multiple rivers to flood at record-high levels, washing out vehicles, flooding basements and cutting power to thousands of homes.

A rare 1,000 year storm dropped over 9 inches of rain in Milwaukee, flooding streets, stranding cars and prompting emergency declarations.
