Durham, Orange and Chapel Hill-Carrboro City Schools will be closed Wednesday, while public schools in Wake and Chatham counties will open late due to the threat of black ice.
The Orange County school system noted that a winter weather advisory is in effect through 11 a.m. Wednesday.
The Wake County Public School System said it would operate on a three-hour delay, while Chatham County Schools said it would operate on a two-hour delay.
“The delay offers drivers the benefit of sunlight to identify any black ice that may remain,” the Chatham school system said in a statement.
By Tuesday, highways and major roads were mostly clear of snow and ice throughout the Triangle. Temperatures climbed above freezing throughout the day Tuesday, and sunshine helped melt lingering slick spots.
But temperatures will likely dip into the 20s overnight, and state officials warned that wet areas on the road will be frozen Wednesday morning.
