In Southern California, between 1 and 3 inches of rain fell in the Los Angeles Basin, Mike Wofford, a meteorologist for the weather service, told SFGATE Friday. Downtown Los Angeles received 2.94 inches of rain. The highest totals were reported in the mountains, ranging from 3 to 6 inches.

Debris flows brought on by the strongest atmospheric river of the season swept a car off a southern California highway and into the ocean and left roads submerged in sludge

In the Los Angeles area, the burn scars that carry the highest risk are those from the Eaton and Palisades fires from January and the Bridge Fire from the fall.

Rain pounded down throughout the Bay Area on Thursday, causing freeways to flood and Santa Cruz County residents to evacuate because of heavy rains and rising water.

The Santa Cruz County Sheriff's Office placed several unincorporated low-lying areas under an evacuation warning Wednesday due to heavy rains and likely flooding from the arriving storm.

Santa Clara and Santa Cruz counties are included in an updated flash flood warning issued by the National Weather Service on Thursday at 8:52 a.m. The warning is in effect until 9:15 a.m.
