LOS ANGELES -- Tens of thousands of people lost power Sunday after a powerful winter storm swept through Northern California, while another storm system in the southern part of the state unleashed mudslides in wildfire burn areas and trapped motorists on a major highway.

A stretch of the scenic route northwest of Los Angeles was expected to remain closed in both directions until Monday while crews tow away stuck vehicles and clear lanes. No injuries were reported.
The rapper Soulja Boy was among those whose cars were mired in the muck that was up to 4 feet (1.2 meters) deep in some areas.
The 28-year-old retweeted a photo of the mudslide and posted: "My car got stuck too almost went into the ocean," along with a prayer emoji.
