A new storm moved into Southern California Saturday morning, bringing heavy rain and winds of up to 80 miles per hour, threatening mud and debris flows in the recent burn areas and prompting a flash flood warning for part of Los Angeles County.

Coastal and valley areas received up to 1 inch of rain per hour during peak rainfall, according to the National Weather Service.

“Given 1-3 inches of rain across (parts of Southern California) roughly 48 hours ago, along with the presence of a few recent burn scars, flash flooding, mudslides and debris flows appear likely,” the NWS said. “This is a very dangerous situation for the terrain of Southern California sensitive to heavy rain impacts.”

In the recent Woolsey Fire burn area, officials issued mandatory evacuation orders for Seminole Springs Mobile Home Estates in Agoura Hills and Paseo Canyon Malibu West in Malibu.

Evacuation centers were set up at the following locations:

— Agoura Hills/Calabasas Community Center, 27040 Malibu Hills Road;

— Santa Monica High School (South Gym), 601 Pico Blvd.;

— Pepperdine University, 24255 Pacific Coast Highway, Malibu.

Downed trees were reported in Toluca Lake and Glendale, but no injuries were reported.

A section of Burbank Boulevard was closed for flooding at the 405 Freeway near Sepulveda Boulevard.

Los Angeles Fire Department officials reported the evacuation of two homes on Courtney Avenue in the Hollywood Hills due to mudflow, pending a new assessment by city inspectors. The homes previously were yellow tagged from a Jan. 17 mudslide.

A winter storm warning was in effect through early Sunday evening for the Los Angeles County mountains, excluding the Santa Monica Range.

The snow level was expected to be at 7,000 to 7,500 feet through Saturday morning and drop to around 6,000 feet by evening, to between 5,000 and 5,500 feet Sunday, according to an NWS statement.

The city of Burbank issued voluntary evacuation orders for residents of Country Club Drive above Via Montana, beginning at 5 a.m. Saturday and continuing through at least 4 p.m.

Disruptions were also expected at lower elevations, including “significant wind impacts possible for Interstate 5 near the Grapevine, where very strong gusts of 70 to 80 mph will be possible.”

The bad weather was blamed for two vehicle accidents on the northbound 5 Freeway at Pyramid Lake, near the L.A. County/Kern County line, which sent nine people to the hospital and claimed the life of a search-and-rescue team member with the Ventura County Sheriff’s Department.

The storm hails from the Gulf of Alaska and taps into a band of moisture stretching from Hawaii to California as a low pressure system parks itself over California, NWS meteorologist Todd Hall said.

Substantial rain was expected to continue Saturday afternoon, with lingering showers through Sunday morning before another bout of rain moves in Monday and Tuesday.
