California atmospheric river’s relentless rains turn burn scars into roaring torrents of mud
Previous atmospheric river events have flooded Northern California, but according to the FOX Forecast Center, this storm is set to be the strongest for Southern California so far this season.
Atmospheric river brings flooding areas devastated by wildfires in Southern California
An atmospheric river brought 2-8" of rain and multiple feet of snow to California since Wednesday evening. The rain prompted flooding across the state. Numerous roads were closed across northern California. Heavy snow prompted CalTrans to briefly hold traffic on Interstate 80 over Donner Pass due to multiple spinouts and heavy snow in the Sierra Nevada.
LOS ANGELES – Torrential rains from a potent atmospheric river soaked nearly the entire state of California Thursday, triggering flash flooding up and down the state and transforming burn scars left from historic wildfires in Southern California into streams of mud.

Video taken from around the burn scar left from the deadly Palisades fire showed roadways becoming mud streams as rainfall rates were estimated to have reached at least an inch per hour. Residents near burn scars in multiple counties had been told to either evacuate or be ready to at a moment's notice as the storm arrived.
"There is mud and debris everywhere," said Gigi Graciette with FOX 11 Los Angeles as she stood along the city's Sunset Boulevard. "You can see tree branches and excess of metals that we believe what was left of someone’s burned home. This is up and down Sunset Boulevard."
Rainfall, mud make roadways impassible around Palisades burn scar
Heavy rainfall rates were too much for some areas around Los Angeles to handle as impassable roadways were encountered around the Palisades burn scar.
The California Department of Transportation (CALTRANS) closed a portion of the Pacific Coast Highway between Santa Monica and Malibu ahead of the storm, and mudslides and debris flow later poured across the highway. "Even workers (along PCH) had to scramble to get out of the way there was so much mud and so much debris," Graciette said.

For residents already dealing with the aftermath of the fires, the mudflows were just adding to the woes.
"Seeing these compounding effects of the rain, plus the soot. When you combine that together, it’s not a great combination. It makes it just that much worse," Palisades resident Michael Fanous told FOX 11. "People haven’t been able to go assess their homes… and more damage is sort of affecting their homes as it stands right now."

Other water rescues are reported to have taken place throughout Southern California, but there were no reports of significant injuries from the wet weather event.
"After the fire occurs and there's so much damage and mobile, loose debris, it doesn't take a whole lot of rain to trigger the downward motion down steep terrain of all that debris," said Ariel Cohen with the National Weather Service office in Los Angeles. "It can potentially become a surging, raging torrent of debris in a matter of minutes."
WIDE SWATH OF US BRACES FOR WEEKEND TRIPLE THREAT OF SEVERE STORMS, FLOODS AND SNOW
The atmospheric river even brought severe thunderstorms to the Los Angeles area with torrential rains, lightning and wind gusts in excess of 60 mph.
According to the FOX Forecast Center, it has been nearly a year since the region had been under a Severe Thunderstorm Warning, as storms generally worked from northwest to southeast across the region.
