SAN FRANCISCO – A third winter-like storm in a week brought rain and strong winds to much of Northern California and snow to the Sierra Nevada on Sunday. Sheets of pouring rain made for treacherous driving.
One person was injured in an accident on Highway 101 that blocked all lanes near San Rafael, north of San Francisco, the California Highway Patrol said.
Showers and thunderstorms happened throughout the day, and officials reminded residents to drive slow, saying there is debris and flooding on the freeways. The CHP said it is handling several collisions in the San Francisco Bay Area.
After a lull Saturday, the system moved into parched California overnight packing precipitation, strong winds, lightning and hail.
The latest storm dumped slightly less rain in the state than the previous systems — with the San Francisco Bay Area and the San Joaquin Valley expected to get up to about half an inch, National Weather Service meteorologist Nathan Owen said.
The National Weather Service issued a strong wind advisory for the San Francisco Bay Area that stayed in effect through Sunday night. Winds delayed arriving and departing flights at the Oakland and San Francisco International airports, officials said.
The weather service warned that dry trees could topple and bring down power lines. "Driving may be difficult, especially for high-profile vehicles," it said.
Pacific Gas and Electric Co. said several there were several power outages in the Bay Area and that power was restored to hundreds of affected customers a few hours later.
Central California could also saw heavy winds.
In Southern California, chains were required Saturday on several roads leading to the Bear Mountain and Snow Summit resorts after several inches of snow fell on the San Bernardino Mountains. A storm Friday dropped 6 inches at higher elevations and brought rain, hail and thunderstorms elsewhere.
The National Weather Service said that more snow is expected before Monday.
The Southern California coast remained under a high surf advisory through Sunday, with unpredictable waves topping 10 feet.
Forecasters have said a strong El Nino weather system could drench California and other parts of the West in the coming months. However, Johnny Burg, a meteorologist with the National Weather Service in Seattle, said he didn't believe the latest Northwest storms were related to El Nino, a warming in the Pacific Ocean that can alter weather worldwide.
