February 4 California storm updates

At least three homes in the Encino neighborhood were impacted by a “debris flow” early on Monday morning, according to the Los Angeles Fire Department.

It was unclear how many other residents were impacted by the debris flow, LAFD spokesperson Nicholas Prange told CNN Monday.

Debris flows are “fast-moving landslides” that can occur during periods of intense rainfall, according to the US Geological Survey.

More than a dozen residents and their pets were evacuated from all nine homes on Lockridge Road, the department said.

High-wind alerts were affecting more than 35 million people across California early on Monday morning, according to the National Weather Service.

Over 14 million people are under a high risk of excessive rainfall on Monday across Southern California, according to the Weather Prediction Center. 

The WPC has issued a rare level 4 out of 4 warning to affected areas including Downtown Los Angeles, Anaheim and Long Beach.

Rainfall rates across this high-risk area could approach 1 inch per hour, which could lead to rainfall totals of 4 to 8 inches, and possibly reach 8 to 14 inches in mountain and foothill terrains.

This event is part of an atmospheric river: a moisture plume pumping off the Pacific Ocean, feeding off warmer-than-average waters.

The National Weather Service has warned of "numerous damaging landslides" in the cities of Malibu and Beverly Hills as a powerful storm drenches California.

Landslides could also hit from the Santa Monica Mountains to the Hollywood Hills and Griffith Park, stretching to the adjacent foothills in the valleys. 

Numerous damaging landslides, flooded roadways, submerged vehicles, and flooded creeks and streams were ongoing in the warning area as of 11:38 p.m. PT, the NWS Los Angeles said.

Automated rain gauges indicate between 5 and 8 inches of rain has drenched those areas, and rainfall can still rise by 1 to 4 inches, the NWS Los Angeles estimated.

The potential impacts include life-threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses as well as destructive and life-threatening landslides.

Locations that will experience flash flooding include Westlake Village, Malibu, Woodland Hills, Encino, Santa Monica, Agoura Hills, Van Nuys, Beverly Hills, North Hollywood, Hollywood, Universal City, Burbank, Griffith Park, Topanga State Park, Calabasas, Pacific Palisades, Malibu Creek State Park, Brentwood and Interstate 405 through the Sepulveda Pass.

"In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain. Do not attempt to cross flooded roads. Find an alternate route," it said. 

At least two homes in the Studio City neighborhood were left with “significant” damage after being struck by a “debris flow,” the Los Angeles Fire Department said Sunday night. 

More than a dozen residents and their pets were evacuated from all nine homes on Lockridge Road, the department said.
