At least two people have died in flooding caused by powerful storms that damaged homes, washed out roads and stranded motorists in Wisconsin, Minnesota and Michigan. In northern Wisconsin, an 84-year-old Illinois man died Tuesday when his vehicle became submerged in a flooded ditch, according to Bayfield County sheriff’s officials, who identified the victim as Delmar Johnson of Tower Lakes, Illinois. A firefighter was able to rescue the man’s wife, also 84, who was a passenger. The firefighter went back in the water and pulled Delmar Johnson from the vehicle, but couldn’t resuscitate him, officials said.
