Before heading out, make sure you are prepared to handle the extreme cold temperatures expected to settle into the area this week.

Door and Kewaunee counties are under a cold weather advisory from 6 p.m. Monday until 10 a.m. Tuesday, as cold temperatures and gusty winds are expected to create wind chills as low as 15 to 30 degrees below zero.

Daily low temperatures are not expected to reach double digits until late next week, with a daytime high of minus 2 degrees forecast for Friday.

Door County Emergency Management Director Jeb Saelens said government buildings can be used as warming shelters during normal business hours, allowing residents to warm up and charge their phones if needed. The county could add additional warming shelter hours if circumstances such as power outages occur.

Saelens said it is important for residents to take proper precautions to stay safe, especially with an increased risk of frostbite and hypothermia. He also encouraged people to check on friends and neighbors to ensure they are handling the bitter cold safely.
