LITCHFIELD — Authorities said at least two people have died in flooding caused by powerful storms that damaged homes, washed out roads and stranded motorists in northern Wisconsin and Minnesota.

In Wisconsin, Bayfield County sheriff’s officials said an 84-year-old Illinois man died Tuesday when his vehicle became submerged in a flooded ditch. A firefighter was able to rescue the man’s wife, who was a passenger.

In nearby Iron County, the sheriff’s department said a 56-year-old man from Montreal, Wisconsin, died in the flooding, but didn’t immediately provide details.

Gov. Mark Dayton plans to travel today to Litchfield and Watkins, which were both slammed by tornadoes on Monday.

The National Weather Service is forecasting another round of thunderstorms today for northern Wisconsin and Minnesota.
