Crews are working to restore power to thousands of people after a winter storm swept through Northern California. The storm also prompted the temporary closure of a major interstate highway after motorists were trapped in the Sierra Nevada by whiteout conditions.

Strong winds and downed trees knocked out electricity for at least 80,000 customers across the Sacramento region Sunday night.

Officials said Interstate 80 from Placer County in California to the state line with Nevada reopened Monday but it remained closed in Nevada's Washoe County.

Officials shut down the highway Sunday after a powerful snow storm reached the Lake Tahoe area as weekend visitors were leaving.

The National Weather Service on Monday issued a winter storm warning for areas in the Sierra Nevada above 4,000 feet (1,200 meters), saying snowy and gusty conditions will limit visibility.
