A third winter-like storm in a week moved out of California on Monday after dumping rain and snow across the sodden state, leaving behind cold temperatures, powerful winds and pounding surf.

The National Weather Service said temperatures would be about 10 degrees colder than normal in Southern California, where overnight temperatures dipped into the 30s, and would barely top 60 during the day.

A high-surf advisory was in effect for San Diego County through Tuesday, with unpredictable waves up to 8 feet lashing the coast, accompanied by dangerous rip currents.

Drivers were urged to use caution on mountain roads where gusts up to 70 mph were predicted. Strong winds delayed arriving and departing flights at the Oakland and San Francisco International airports over the weekend, officials said.

Chains were required Monday on several roads leading to the Bear Mountain and Snow Summit resorts after several inches of snow fell on the San Bernardino Mountains. The storm that whipped up Friday dropped more than 6 inches at higher elevations and brought rain, hail and thunderstorms elsewhere.

North of Los Angeles, a 35-mile stretch of northbound Interstate 5 near Castaic reopened after flash flooding sent mud and rocks into lanes.

Sheets of pouring rain made for treacherous driving this weekend. Two parents were killed and their young children were injured when their vehicle apparently hydroplaned and rolled down an embankment during heavy rains in Alameda County on Sunday.

Fire Battalion Chief Stephanie Radecke said a 5-year-old boy and 6-year-old girl survived the crash off a freeway between Livermore and Tracy. The boy suffered head trauma.

Forecasters have said a strong El Nino weather system could drench drought-stricken 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 storms were related to El Nino, a warming in the Pacific Ocean that can alter weather worldwide.
