Firefighter swept into ocean in debris flow as heavy rain pounds Los Angeles

One of the strongest storms of the season slammed fire-ravaged Los Angeles with heavy rain on Thursday, sending streams of mud and debris across roadways and sweeping a fire department vehicle off a Malibu road into the ocean, authorities said.

A member of the Los Angeles Fire Department was inside the vehicle when it was swept off the road by a large debris flow and into the ocean, according to the department.

"Fortunately, the member was able to exit his vehicle and reach safety with minor injuries. He was transported to a local hospital as a precaution," spokesperson Erik Scott said.

In the Southern California city of San Juan Capistrano, two people were rescued early Friday after getting trapped in the fast-moving San Juan Creek, the Orange County Fire Authority said. They were holding onto trees and bushes to try to avoid getting swept away, the fire authority said.

"One of the victims, who had been dragged downstream by the swift current, jumped into the arms of the helicopter rescuer," the fire authority said.

The atmospheric river dumped 6.34 inches of rain in Los Angeles County, prompting mudslides in the burn scar areas from last month's devastating Palisades Fire, Los Angeles ABC station KABC reported.

Videos captured by KABC showed bulldozers pushing streams of muddy sludge out of the roads and firefighters trudging through nearly waist-deep swamps of water and mud.

The storm also brought a line of severe thunderstorms with 70 mph wind gusts to Los Angeles County, and a possible tornado hit a mobile home park near Oxnard, California, about 60 miles from LA.

LA Mayor Karen Bass said the city prepared for the storm by clearing catch basins of fire debris, offering residents over 6,500 sandbags, setting up over 7,500 feet of concrete barriers, and having systems in place to capture polluted runoff.

Sheriff's deputies helped residents prepare with sandbags and passed out mud and debris safety tips, Los Angeles County Sheriff Robert Luna said at a news conference Wednesday. "Our homeless outreach teams ... are actively notifying individuals living in flood-prone areas like the LA River, Coyote Creek and other key waterways, urging them to relocate."

Evacuation warnings were announced for parts of fire burn zones, including areas impacted by the Palisades Fire, and an evacuation order was issued for parts of Sierra Madre affected by the Eaton Fire, according to KABC.

All Malibu schools were closed Thursday and Friday, according to the Santa Monica-Malibu Unified School District.

The sheriff urged residents to prepare in the event they needed to evacuate.

"Unfortunately, we've witnessed numerous, numerous instances in the past of swift-water rescues where people were caught in dangerous, fast-moving water, and obviously, we want to prevent that," he said.

"Nothing that you have back home is worth your life. If you decide to stay in your property in an evacuated area, debris from the burn scar areas and storm may impede roads, and we may not be able to reach you," he warned.

Before pummeling LA, the storm first hit Northern California, bringing rain and flash flooding to the San Francisco Bay area.

Further north, the same storm system brought whiteout conditions and car crashes to Interstate 84 in Oregon.
