MADISON, Wis. (AP) -- State health officials are investigating whether three deaths last week were related to the swath of frigid temperatures.
Wisconsin Emergency Management says the deaths were in Ashland, Marquette and Milwaukee counties. All three people died Friday.
The Department of Health Services said Tuesday the deaths remain under investigation, but officials suspect the cold weather was a factor.
The string of cold temperatures is expected to continue a little longer. The National Weather Service has issued a statewide wind-chill advisory through Wednesday at noon.
Temperatures are expected to remain bitterly cold through Wednesday morning, with wind chills ranging from minus 25 to minus 25 across the state. The weather should start warming up in the afternoon, and by the weekend temperatures should be in the 30s.
