Officials from the Georgia Department of Transportation said Wednesday night that they were concerned with sub-freezing overnight lows potentially leading to layers of black ice coating roads that might appear to be safe.
Residents are heeding the warning. School districts and state and local governments stretching from northwest to coastal Georgia announced that offices and classrooms would remain closed Thursday.
Meanwhile, Georgia Gov. Nathan Deal said emergency workers, police, and the National Guard on Thursday would help drivers recover cars they abandoned after getting stuck in Tuesday's storm.
