The Orange County school system will open on a two-hour delay Monday “due to the possibility of hazardous road conditions.”

The district made the announcement on Twitter on Sunday evening.

Alamance-Burlington schools will also open on a two-hour delay Monday, the district said on Twitter.

Although the Triangle was mostly spared, a winter storm left snow and ice across parts of western and central North Carolina on Saturday night and Sunday. Gov. Roy Cooper declared a state of emergency Sunday for all 100 counties in an effort to quickly restore power to more than 118,000 Duke Energy customers.

Temperatures are expected to drop into the upper 20s to mid 30s Sunday night, according to the National Weather Service in Raleigh.

“There is some concern for refreezing of wet spots on the pavement tonight, particularly since there is unlikely to be much opportunity for drying,” the weather service said on its website.

But the weather service did not issue a black-ice advisory. The “hardest hit areas” -- Forsyth, Guilford and Randolph counties -- “have been above freezing long enough today that much or all of this should melt before temps drop back below freezing, and ground temps are a bit warmer than the elevated surfaces,” the weather service said.

Temperatures are expected to stay below normal Monday, with highs into the mid-40s.
