UPDATED with latest: The flash flood warnings announced earlier for Northwestern Los Angeles Country and Ventura County have been extended to all of L.A. County, per the National Weather Service just before 7 p.m.
Some flash flooding already has been reported, the NES said, in areas of Fillmore, Ojai and Santa Paula, Santa Clarita, especially in the burn scar areas from recent-ish fires like the Thomas Fire.
In Chatsworth, two cars fell into a sinkhole tonight, trapping two people, authorities said. The incident was reported about 7:20 p.m. at 11414 Iverson Road, where one car toppled on top of the other in the hole, according to the Los Angeles Fire Department.
Because the roadway was completely compromised, authorities said it could not support emergency vehicles, so firefighters slid ladders down to help the two trapped motorists. Both people were taken to a hospital with minor, non-life threatening injuries, the LAFD reported.
The incident comes as total rainfall tonight through tomorrow morning across Los Angeles is expected to be between two and five inches. Some areas, like Ojai, Fillmore and Pasadena are expected to get even more.
PREVIOUSLY at 4:15 PM: Santa Barbara emergency response officials updated the situation in the region north of Los Angeles this afternoon and it is not good. Among the issues — beyond heavy rain and flooding — is that the 101 is now closed at multiple points, effectively cutting off traffic going northbound into Santa Barbara and also traffic going Northbound out of the county.
“The CHP is in the process of closing 101 at state route 33 in Ventura in order to stop traffic from coming into the county,” said Sheriff Bill Brown. “Several lanes that have been closed in Carpenteria [south of Santa Barbara]. The highway has also been closed at Cabrillo, according to the sheriff.
North of the seaside city, the 101 is closed at Mariposa because “significant rockfall at Gaviota,” said the sheriff, who also indicated that it will remain closed “until some time tomorrow.
“There are big boulders blocking that,” he added.
Another official indicated that a declaration of a state of emergency is likely soon, with a “signed declaration of emergency being presented to supervisors” shortly.

A series of powerful storms are expected to pass through Northern California this week, moving into Southern California thereafter. An atmospheric river event pounded Northern California last week causing flooding, power outages and heavy snowfall in the mountain areas.
President Joe Biden approved an emergency declaration for the entire state of California on Sunday and authorized the Federal Emergency Management Agency to coordinate disaster relief efforts and provide emergency resources, the White House said in a statement.
In a move likely to snarl traffic between Beverly Hills-West Hollywood and the Valley, the Los Angeles Department of Transportation implemented a road closure of Mulholland Drive between Laurel Canyon Boulevard and Coldwater Canyon Drive in anticipation of the storm activity.
Partly sunny skies will return Wednesday and Thursday, but more rain is possible next weekend, possibly as early as Friday night, according to the NWS.
