Dozens of sinkholes and washed out roads were reported Sunday as flash flooding triggered by heavy rainfall swamped several towns from northern Minnesota and Wisconsin to Upper Michigan.

"The majority of us can't even get home. Roads are collapsed. Bridges are collapsed. Roads are covered in water. Whatever roads aren't collapsed it depends on how heavy of a vehicle you drive whether or not you are able to drive on those roads," Chassell, Michigan, resident Tom Cowell told the AP. "This is a pretty wild experience that we are having here."

A flash flood emergency was declared Sunday for the central and southern areas of Houghton County, Michigan, where residents were urged to shelter in place , according to a National Weather Service flash flood warning. The area received 4 to 7 inches of rain in seven hours.

U.S. Highway 2 in Wisconsin was washed out early Sunday, the Bayfield County Sheriff's Office told the AP. The waters from the flooding isolated an animal shelter along the roadway in Ashland, prompting the owners to move four cats and 15 dogs to a farm nearby.
