The National Weather Service issued a hazardous-weather outlook until this afternoon as water from melted ice is expected to freeze again on road surfaces in the overnight hours, creating black ice and making travel extremely dangerous.
Temperatures were expected to drop near the freezing mark and inch below freezing by dawn, authorities said.
By midafternoon today, temperatures are expected to reach about 50 degrees, said Bruce Cherry, a meteorologist for the National Weather Service.
“There definitely could be slick spots on the roads tonight,” Cherry said Thursday. “I think by late morning your icing problems should be mostly done.”
Bridges and overpasses that haven’t been treated for icing will be especially slick, he said.
Columbia County’s Emergency Management director, Pam Tucker, said Thursday evening that downed power lines and trees in roads continued to plague many portions of the county, as did traffic signal outages.
Nearly 30 county roads were closed Thursday.
Tucker advised any motorists who must venture out to be cautious of sheriff’s deputies directing traffic and crews working along roads to restore power.
“Also, be mindful of some temporary stop signs that are out around the county,” she said.
