The National Weather Service predicted a new surge of rain and snow Monday as another storm moved in from the northwest.
The next series of storms will bring more than an inch of rain to most of the Southland, with moderate to heavy snow in mountain areas.
The NWS has declared a winter storm warning from 4 a.m. to 8 p.m. Monday.
That included a snow watch for the highest mountains in the region, where eight to 12 inches of snow may fall above the 7,000-foot level; and eight inches may fall as low as the 5,500-foot mark, which is higher than the summit of Mt. Wilson.
The snowfall may affect Big Pines Highway between Palmdale and Wrightwood, roads near Frazier Park, and roads in and leading to the Big Bear area, the NWS said.
Angeles Forest Highway between La Canada and Palmdale may be too low for snow, but could see heavy rain.
The NWS also forecast continued high surf and dangerous riptides along the Orange County coastline into Monday morning, when they are expected to subside.
The surf was expected to range between 4 and 7 feet with sets up to 8 feet, according to the NWS.
Forecasters also issued a high surf advisory for these beaches. The advisory began Sunday morning and will remain in effect until at least 5 a.m. Monday.
Los Angeles County flood experts said the approaching storm that is predicted to drop heavy rain Monday should not be strong enough to cause mud or debris flows in the Station Fire area.
The Department of Public Works said today that between 3/4ths and 1- 1/4th inches of rain is expected to fall Monday in foothills of the burned Angeles National Forest, in the arc from Pasadena north and west through Altadena, La Canada-Flintridge and Sunland-Tujunga to Lakeview Terrace.
The county and emergency workers have a three-phase alert system to activate if a storm appears to be strong enough to trigger either localized or area-wide debris flows, mudslides or flooding.
Between the storm forecast and the current condition of the once-burned mountains, the area remains below the threshold for any of those alarms, county officials said.
