VIDEO/PHOTOS: The sporadic change in the weather is making ice conditions dangerous.
So before you head out to fish or snowmobile, first responders are sharing life-saving warnings.
Dozens of firefighters from Racine and Kenosha counties, along with the U.S. Coast Guard, trained for ice rescues over the weekend at Eagle Lake.
It comes after two Sun Prairie boys died after falling through ice in a retention pond earlier this month.
"There’s no such thing as safe ice," U.S. Coast Guard Andrew Brewster said. "If you fall into the ice, you have to have a plan before getting into that situation."
If you are heading on the ice, firefighters say to pay attention to ice conditions, wear warm enough clothing and let someone know where you are going.
