Five people have reportedly died as heavy rain drenches fire-ravaged southern California. Thousands of people are evacuating their homes because the rain is raising the risk of mudslides on hills stripped by the flames.
The five bodies were found in the Montecito area of Santa Barbara County, Santa Barbara County Fire Department Capt. Dave Zaniboni told The Associated Press.
Montecito has seen heavy mud flows that destroyed homes and prompted dramatic rescue operations. "Heavy rains have triggered massive runoff," Mike Eliason, a public information officer for the Santa Barbara County Fire Department, said on Twitter. "Access is difficult/delayed to due to — at some locations — waist deep mudflow, trees, and wires down."
Rescue workers in bright yellow jackets waded through deep mud and debris, searching for people in need of aid. Homes sat crumpled in destroyed in pools of dark muck.
Some 21,000 people have evacuated in large swaths of southern California, according to The Associated Press, including vulnerable areas of Santa Barbara and Ventura counties. That's where the Thomas wildfire raged last month. It was the largest in California's history, burning more than 280,000 acres and destroying more than 1,000 structures.
In Los Angeles County, several canyon areas are also under mandatory evacuation orders due to the heavy rains.
Just an inch of rain fell in southern California last month, drying out the ground, as reporter Danielle Karson tells our Newscast unit. In areas where the fire burned, there's almost no ground vegetation. Meteorologist Joe Sirard tells Danielle that this can cause problems.
"When we get short-term heavy rain like we're getting right now, it will build up debris in the mud in these areas and it comes right down the mountain," Sirard says. "So it could be a dangerous situation."
The National Weather Service is warning of the potential for flash flooding "for much of Santa Barbara, Ventura and Los Angeles Counties," with rainfall rates as high as an inch and a half per hour.
Residents of vulnerable areas are also piling up sandbags to try to protect their homes. The AP reports that the Ventura County's Sheriff's Office says "jail inmates have been filling sandbags at the rate of 2,000 a day."
And the California Highway Patrol has closed the coastal 101 freeway in both directions for "flooding and debris flows." Topanga Canyon "was also closed in both directions due to a mudslide north of Pacific Coast Highway," member station KPCC reports.
Authorities have also closed the Sepulveda Basin recreation area in the San Fernando Valley, which will cause closures on the nearby 405 freeway, according to the Los Angeles Police Department.
