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. The storms were blamed for at least two deaths earlier in the week. Some 70,000 homes and businesses had no power overnight, according to Find Energy.
The system brought the wettest Christmas season to downtown Los Angeles in 54 years, the National Weather Service said.
CBS Los Angeles points out that the National Weather Service said, “The flooding threat will be exacerbated … due to the super saturation of all of the area. “Any rainfall that occurs will immediately turn to runoff.”
Roads in the 5,000-resident town of Wrightwood were covered in rocks, debris and thick mud on Thursday. With power out, a gas station and coffee shop running on generators were serving as hubs for residents and visitors.

With more rain on the way, more than 150 firefighters were stationed in the area, said San Bernardino County Fire spokesman Shawn Millerick.
“We’re ready,” he said. “It’s all hands on deck at this point.”

A falling tree killed a San Diego man Wednesday, fire officials confirmed to the CBS affiliate there, KFMB-TV. Farther north, a Sacramento sheriff’s deputy died in what appeared to be a weather-related crash.
Areas along the coast, including Malibu, were under a flood watch until Friday afternoon, and wind and flood advisories were issued for much of the Sacramento Valley and the San Francisco Bay Area.
Southern California typically gets half an inch to 1 inch of rain this time of year, but this week many areas could see between 4 and 8 inches, with even more in the mountains, National Weather Service meteorologist Mike Wofford said.
More wind and heavy snow were expected in the Sierra Nevada, where gusts created “near white-out conditions” and made mountain pass travel treacherous.
Gov. Gavin Newsom declared emergencies in six counties to allow state assistance.
The state deployed resources and first responders to several coastal and Southern California counties, and the California National Guard was on standby.
