"Untreated roads will become snow-covered and travel difficult, particularly between 5 p.m. and 11 p.m. when the heaviest snow is expected to fall," the weather service said.

Snow rates are likely to peak near 1 inch per hour in the evening, it added. "The expected heavy, wet nature of the snow will make shoveling hazardous."

More snow was expected Saturday night and Sunday, the weather service said.
