Cobb County will resume normal government operations at 10 a.m. Thursday after heavier-than-expected snowfall Tuesday night.
County Manager Rob Hosack said the delayed opening should give the transportation department time to treat icy roads and avoid forcing county employees to drive to work before sunrise, according to a statement from the county.
Transportation department crews are scheduled to work throughout the night Wednesday, treating roads with a mix of gravel and salt in an effort to prevent black ice from forming.
Cobb roads were mostly open and passable by Wednesday afternoon, but county officials cautioned against driving at night.
Cobb and Marietta school systems will both remain closed Thursday, along with schools throughout the metro area.
