Torrential rain caused mudslides and sent creeks and rivers out of their banks across much of south-central and southeast Minnesota late Friday and early Saturday.
The National Weather Service received reports of more than 8 inches of rain overnight near Spring Valley, more than 7 inches at Lanesboro and Ellendale, and more than 6 inches near Caledonia, Preston, Chatfield and New Richland.
The flooding continued through the day Saturday along creeks and rivers swollen by the storm runoff.
In Spring Valley, Mayor Justin Mlinar reported just after 6 a.m. Saturday that all streets were closed due to flooding. Photos posted to social media showed floodwaters flowing along streets in the city’s downtown, near Spring Valley City Hall.
