MADISON, Wis. (AP) _ State emergency officials are warning of another Arctic surge that's expected to sweep across the state this weekend.
The National Weather Service says cold air will begin pouring into Wisconsin starting Saturday night, bringing life-threatening temperatures that could linger through Tuesday.
Lows on Sunday night could range from minus 10 to minus 25, with wind chills of minus 30 to minus 40. On Monday, highs will still be below zero, ranging from minus 5 to minus 15.
Wisconsin Emergency Management says those conditions could lead to major trauma in a matter of minutes. It says frostbite can occur on exposed skin in less than 10 minutes, and people are especially vulnerable to hypothermia, which is marked by shivering and confusion.
Officials also remind residents to keep pets indoors.
