Downpours of up to an inch of rain per hour have much of Los Angeles, Orange, Riverside and San Bernardino counties under flood advisories and other weather-related warnings throughout Thursday afternoon, according to the National Weather Service.

Residents of Idyllwild, Mountain Center and Pine Cove were being asked to shelter in place because of deteriorating road conditions, county officials said in a tweet. Idyllwild School at 26700 Highway 243 in Idyllwild was being set up as a care and reception center.

In the Angeles National Forest, Mt Baldy Road was closed in the area of Snow Crest Lodge due to flooding.

Los Angeles County

In Long Beach, he 710 Freeway was temporarily closed near PCH about 4:30 a.m. after a BMW got stuck in a flooded portion of the roadway and needed help getting out, according to the California Highway Patrol’s traffic incident log.

Commuters who may come across flooded roadways Thursday were reminded by the Weather Service to “turn around, don’t drown.”

Further up the coast, Topanga Canyon Boulevard was closed from PCH to Grand View Drive amid mud and debris slides, with some cars stranded on the road, Caltrans said. Motorists were asked to avoid the area.

Several road closures had been in place in Burbank, including on Country Club Drive, a steep street experienced dangerous mudflow as residents were trying to evacuated during a storm last year. They were lifted shortly before 2 p.m., but residents were urged to keep updated on conditions with more rain expected later in the week.

In Hermosa Beach, a sinkhole prompted road closures in the area of 35th Street and Palm Drive Roadway.

Video showed a crew working to repair the sinkhole.

Orange County

Officials had to close a stretch of Pacific Coast Highway from Seapoint Street to Goldenwest Street in Huntington Beach due to flooding, a Police Department spokesperson told KTLA.

Caltrans later updated the closure information stating the highway was closed from Seapoint Street to  Warner Avenue.

It was unclear how long the closure would be in place.

In Brea, eastbound Carbon Canyon Road was shut down from Valencia Avenue to the San Bernardino County line due to flooding around 12:30 p.m., and the closure was expected to last at least four hours.

Flooding also prompted multiple closures in Laguna Beach.

Laguna Canyon between Canyon Acres and El Toro was shut down, as was Broadway Street between Beach and PCH, according to Laguna Beach officials.

Ventura County

In Ventura County, numerous mudslides and debris flows prompted the closure of Highway 33 between Fairview Road in Ojai and Lockwood Valley Road, according to Caltrans. Emergency vehicles and residents would still be allowed through, however.

Bad commute

The wet weather is also being blamed for cars hydroplaning and crashing into guard rails during the morning commute.

A SigAlert was issued about 2:30 a.m. after a vehicle ended up blocking the carpool, one, two and three lanes on the northbound 405 Freeway at Santa Fe Avenue.

Video from Riverside County showed one vehicle had overturned following a crash on the 215 Freeway near Highway 74.

And several vehicles were involved in a collision on the eastbound 60 connector road to the southbound 71 Freeway. At least one of the vehicles ended up in lanes temporarily blocking traffic.

The rainy weather is expected to continue well into Thursday evening and possibly return on Friday.
