Downpours lead to flash flooding; more storms on way


A succession of thunderstorms passing through Minnesota is likely to continue through Monday, and meteorologists are on the lookout for flash floods or tornadoes.

Sunday's storms produced some flooding, especially in Mower County and Mitchell County, Iowa. The National Weather Service reported the flash floods made conditions dangerous in those areas and no travel was advised.

In issuing a flash flood warning for the area, the Weather Service said 4 to 8 inches of rain had fallen by Sunday night. KAAL reports the runoff will continue to boost water levels, especially on the Cedar River. Roads that were underwater included U.S. Highway 218 near Osage, Iowa, and Minnesota Highway 56 west of Leroy.

The thunderstorms that passed through the region produced 60 mph gusts in the Rochester area and some scattered street flooding and downed trees in the Twin Cities.

Forecasters expect stormy weather to continue through Monday night and a flash flood watch is in effect for central and eastern Minnesota and western Wisconsin. The watch area also covers northeastern Minnesota, including Duluth, Lake Superior's north shore, and the Iron Range.

MPR meteorologist Paul Huttner was live blogging the progress of the storms. Straight line winds prompted authorities to sound warning sirens in Dakota County.

No mention of any snow.
