Live updates: Storm brings flooding, stalled cars near Burbank airport

Residents living in and around recent burn scar areas in the Pacific Palisades are preparing for heavy rain.

Residents living in and around recent burn scar areas in the Pacific Palisades are preparing for heavy rain expected overnight, with officials urging people to be ready for possible evacuations.

In the Palisades fire zone, a portion of Topanga Canyon Boulevard was closed on Sunday night as the storm approached. City and county officials say the combination of saturated hillsides and firedamaged terrain increases the risk of mud and debris flows.

"We seem to be in nature's spotlight lately," resident Will Adams said as neighbors made storm preparations across the Palisades.

Forecasters warn the incoming system could be the strongest storm of the season, bringing heavy rain, strong winds and a threat of flash flooding. Officials are advising residents to secure outdoor items, gather emergency supplies and prepare for possible power outages.

"Given the fires, I should have a better plan, but I don't," Adams said. "But my wife always has a plan, so I'll rely on her."

Similar preparations were underway in Altadena, where residents near burn scar areas picked up sandbags and stocked up ahead of the storm.

Authorities announced road closures on Topanga Canyon Boulevard due to the risk of mudslides, falling rocks and debris.

"We must kind of make a move or be thoughtful about what kinda rain is coming," a Pacific Palisades resident said. "It's seasonable, so I'm not threatened. I think we're going to get a good soaking and a bit of rain."

The heaviest rainfall is expected on Monday morning and afternoon. Officials are urging people in burn scar areas to stay alert, have an emergency plan and be prepared to leave if evacuation orders are issued.

A Winter Storm Warning will be in effect for the northern Ventura County Mountains and eastern San Gabriel Mountains from 10 a.m. on Monday through 9 a.m. on Thursday as Southern California is hit with several powerful winter storms.

Monday alone could bring 3 feet of snow to the highest elevation mountain regions.

A Winter Storm Watch has also been issued from Tuesday at 9 p.m. through Thursday at 9 a.m. for the western San Gabriel Mountains and Highway 14 Corridor, western Antelope Valley foothills, eastern Antelope Valley foothills, Santa Barbara County interior mountains, southern Ventura County mountains and Interstate 5 corridor.

A series of powerful storm systems is expected to bring widespread rain to the region beginning overnight, prompting Los Angeles city officials to issue evacuation warnings and urge residents to prepare for potentially hazardous conditions.

A series of powerful storm systems is expected to bring widespread rain to the region beginning overnight.

The city of Los Angeles issued an evacuation warning due to the risk of debris flows for some residents living in several burn scar areas, including the Palisades, Hurst and Sunset fire zones.

The warning goes into effect at 9 p.m. on Sunday and lasts through 9 a.m. Tuesday.

Authorities are urging residents to begin storm preparations immediately.

Recommendations include securing outdoor furniture or lightweight items, keeping an emergency supply bag accessible, and adjusting travel plans when possible to avoid the heaviest rain. Local fire stations are distributing sandbags.

Randy Stoklos, a resident who was able to save his home during the Palisades Fire, said he is preparing for an active week but remains calm.

"I've heard and gotten the warnings that we must kind of make a move and be thoughtful of what kind of rain is coming, and it's seasonable, so I'm not threatened. I think that we're going to get a good soaking and it's going to be a bit of rain," he said.

The storms are expected to continue into Monday, with the city advising residents to stay aware of rapidly changing conditions and follow all official safety guidance.

The city of Los Angeles issued evacuation warnings for people living in burn scar areas, after a flood watch was issued for a wide swath of Los Angeles County from Monday morning through Monday evening. Rock and mud slides are possible near steep terrain, and debris flows are possible on burn scars.

Mayor Karen Bass warned residents in those areas to take precautions and be prepared for potential emergency warnings.

"Ahead of heavy rain forecasted this week, first responders, Public Works crews, and city personnel are taking action to keep Angelenos safe and will be ready to respond to any potential impacts," Bass said in a statement late Saturday. "This is likely to be another significant rain event. All Angelenos -- especially those in burn scar areas -- are encouraged to follow official guidance, use caution on the roads, plan ahead, and stay informed."

The warning goes into effect at 9 p.m. on Sunday and lasts through 9 a.m. Tuesday.
