Icy conditions were also reported on highways in the mountains.
Authorities closed the snow gates at the north end of Sunrise Highway, near state Route 79, due to ice and drifting snow as plow crews continue to work, according to the DPW.
Authorities were requiring motorists to use vehicle snow chains on Sunrise Highway as well as on county roads S2 and S22, although no snow was falling in the Borrego Springs area around noon and the roads were clear, the DPW reported. Crews were sanding roads on Palomar Mountain and the roads were clear.
Cleveland National Forest park rangers were turning around two-wheel drive vehicles on Palomar Mountain without chains, according to the California Highway Patrol.
Park rangers were also requesting that snow chains be required in the vicinity of state Route 76 and Nate Harrison Grade in Pauma Valley because three to four inches of snow was in the icy roadway, which was especially slick in shaded areas, the CHP reported.
Forecasters expected the weather to improve on Saturday, although roads could remain icy and slick in some mountain areas.
According to the National Weather Service, a frost advisory will be in effect from midnight Saturday until 8 a.m. Sunday.
