From CBS:
A strong storm system that brought relentless winds, rain and snowfall to California this week was expected to ease Friday, but there was still a risk of high surf along the coast, flash flooding near Los Angeles and avalanches in the Sierra Nevada.
Waves near the San Francisco Bay Area could reach up to 25 feet Friday, parts of Southern California were at risk of flooding, and avalanches could hit the Lake Tahoe area, officials warned. Residents were told to be ready to evacuate the mountain town of Wrightwood about 80 miles northeast of Los Angeles because of mudslides. Atmospheric rivers carried massive plumes of moisture from the tropics during one of the busiest travel weeks of the year.
