A cold weather advisory has been extended for the entire Chicago area as dangerous wind chills are expected in coming days.
According to the National Weather Service, the advisory will once again be in effect from 9 p.m. Monday until noon Tuesday.
A previously issued advisory goes into effect at 6 p.m. Sunday, and will run through noon Monday, according to officials.
While wind chills Sunday and into Monday morning could drop well below zero, the coldest wind chills are expected to impact the area Monday night and into Tuesday morning, with low temperatures falling below zero and wind chills of up to 25 degrees below zero, according to forecast models.
At those temperatures, frostbite can occur in as little as 30 minutes on exposed skin, leading Chicago and many suburban communities to offer warming centers to provide relief from the frigid temperatures.
