LOS ANGELES (AP) -- Nearly 4,000 people remain without power around Southern California after a storm that knocked down power lines, snarled roads and left a blanket of snow in the mountains.

At its peak, the storm that began Sunday left some 21,000 people without power. Southern California Edison says about 4,000 customers remain without electricity on Monday morning.

About 4,300 customers in the San Diego area lost power shortly before 1 a.m. but electricity has been restored.

The storm dumped nearly an inch of rain in downtown Los Angeles and two to three inches in coastal Malibu and the Santa Monica Mountains.

The mountains got new snow and could see another inch or two as the storm moves away.
