Thousands of customers had no electricity Monday because of damage from the latest in a week's worth of storms, and experts warned that the risk of mudslides has not eased even as wet weather begins moving out of the region.

Mud, snow and water also had closed several major highways.

Near San Diego, mud and minor rock slides prompted the California Highway Patrol officials to shut Route 78 through a burn area between Ramona and Escondido.

In the Sierra, a nearly 130-mile stretch of Interstate 395, from just north of Bishop to the Nevada state line, was closed because of snow, the California Department of Transportation. Interstate 80 through the Sierra between Sacramento and Reno, Nev., was reopened Monday after being shut down part of the weekend but chains were required, according to a CalTrans Web site.

"It still is a very hazardous situation," she said.

About 2,000 Los Angeles customers remained in the dark because of the stormy weather early Monday, the Department of Water and Power said. Some 700 Southern California Edison customers also had no power, mostly in mountain communities.

More than 7,000 customers were without power in southern California on Sunday evening, and the utilities said most of the outages were weather-related. Department of Water and Power officials said about 3,600 Los Angeles customers were in the dark, most of them in North Hollywood.
