Warnings Issued When Storm Brings Rain and Snow to Southern California

A cold winter storm will bring showers in southern California valleys and snow at higher elevations through Monday.

Rainfall amounts are not expected to be significant: just 0.10” to half an inch at lower elevations, with potentially up to an inch of rain in the foothills of the San Gabriel Mountains, according to the National Weather Service.

Snow levels will drop to 2,500 feet on Monday, creating difficult driving conditions in the mountain passes and Antelope Valley.

Two to three inches of snow is possible on the 5 Freeway through Grapevine, on Highway 14 near Acton and on Highway 33 north of Ojai, the NWS said.

Winter storm warnings have been issued for the mountains of Riverside County and San Bernardino County, where forecasters are forecasting 4-8” of snow above 5,000 feet, with potential for one foot of snow above 6,000 feet.

In the valleys, daytime high temperatures will be in the 40s and 50s.

“Strong northeasterly winds could affect parts of Los Angeles and Ventura counties Monday night through Tuesday,” the NWS said.
