Californians find themselves on high alert as a second wave of severe flooding looms, with the festive atmosphere of Christmas Day overshadowed by roads transforming into rivers and mudslides consuming homes.

This holiday season in the Golden State seems destined to be a washout, with meteorologists predicting up to eight inches of rain drenching regions including Los Angeles County and Santa Barbara over the coming days.

As a series of winter storms continues to unleash flash floods and even tornadoes, California officials are urging holiday travelers to steer clear of the roads to ensure their safety.

The relentless weather has forced hundreds of residents to evacuate, and on Christmas morning, PowerOutage.com reported that around 160,000 homes were left in the dark without electricity.

In response to the escalating situation, Governor Gavin Newsom has declared a state of emergency across several counties, including Los Angeles, Orange, Riverside, San Bernardino, San Diego, and Shasta, as the combination of strong winds and heavy rain intensifies.

Particularly at risk are areas like Altadena, which, having been ravaged by wildfires earlier this year in January, now face a new threat. Residents who were in the midst of rebuilding their homes have seen their partially-constructed properties severely impacted by the floods.

The burn scar areas were also stripped of vegetation by fire, making the land less able to absorb water.  

Storms began to move in late Tuesday evening and were expected to intensify throughout Christmas Day, meanwhile a ‘clipper’ weather system is due to submerge much of the West Coast and Midwest in rain and snow. 

The holiday period is forecast to be a washout for the Golden State this year, with meteorologists warning that up to eight inches of rain is expected to hit several areas including Los Angeles County and Santa Barbara over the next four days

Stormy weather struck California on Christmas Day, prompting hundreds of evacuations

San Bernardino County firefighters said they rescued people trapped in cars Wednesday when mud and debris rushed down a road leading into Wrightwood, a resort town in the San Gabriel Mountains about 80 miles (130 kilometers) northeast of Los Angeles. It was not immediately clear how many were rescued.

Firefighters also went door to door to check homes, and the area was under a shelter-in-place order, officials said. An evacuation order was issued for Lytle Creek, also in the San Gabriel Mountains.

Travis Guenther and his family were trapped in Lytle Creek after roaring waters washed out the only bridge in or out of their neighborhood. More than a dozen neighbors took shelter at a community center or found hotel rooms.

‘Everybody that left to go to work this morning is stuck,’ he said. ‘Half the families are here, and half the families are on the other side of the creek.’

Guenther said he had plenty of supplies and was coordinating with other in the community of about 280 people. Two nurses who live on his street offered to help anyone who may need medical attention.

Janice Quick, president of the Wrightwood Chamber of Commerce and a resident of the mountain town for 45 years, said a wildfire in 2024 left much of the terrain without tree coverage.

The storm also stranded Dillan Brown, his wife and 14-month-old daughter at a rented cabin in Wrightwood with almost no food and only enough diapers for about another day. 

Roads leading off the mountain and to a grocery store became blocked by rocks and debris, Brown said.

A resident learned of his situation and posted a call for help in a Facebook group. In less than an hour, neighbors showed up with more than enough supplies to ride out the storm, including bread, vegetables, milk, diapers and wipes.

‘I think we’re a little sad and upset that we’re not going to be home with our families,’ Brown said, but the ‘kindness shown is definitely an overwhelming feeling.’

Areas along the coast including Malibu were under flood warnings until Wednesday evening, and wind and flood advisories were issued for much of the Sacramento Valley and the San Francisco Bay Area.

Several roads including a part of Interstate 5 near the Burbank Airport closed due to flooding.

The storms were the result of multiple atmospheric rivers carrying massive plumes of moisture from the tropics during one of the busiest travel weeks of the year.

Hundreds of residents have been evacuated, while 160,000 homes were without power on Christmas morning, according to PowerOutage.com

Southern California typically gets half an inch to 1 inch (1.3 to 2.5 centimeters) of rain this time of year, but this week many areas could see between 4 and 8 inches (10 to 20 centimeters) with even more in the mountains, National Weather Service meteorologist Mike Wofford said.

Heavy snow and gusts created ‘near white-out conditions’ in parts of the Sierra Nevada and made mountain pass trave treacherous. 

Officials said there was a ‘considerable’ avalanche risk around Lake Tahoe, and a winter storm warning was in effect until Friday morning.

Gov. Gavin Newsom declared a state of emergency in six counties to allow state assistance in storm response.

The state deployed emergency resources and first responders to several coastal and Southern California counties, and the California National Guard was on standby.

The California Highway Patrol reported a seemingly weather-related crash south of Sacramento in which a Sacramento sheriff’s deputy died. 

James Caravallo, who was with the agency for 19 years, was apparently traveling at an unsafe speed, lost control on a wet road and crashed into a power pole, CHP Officer Michael Harper said via email.
