Southern California storm: Region hit with heavy rain, mountain snow, gusty winds

Another storm moved through Southern California Wednesday, bringing rain, wind and even snow to some neighborhoods that wouldn't normally see it. 

The storms led to power outages and school closures in mountain communities. Homes in La Cañada Flintridge and Beverly Crest were damaged by mudflow and debris resulting in evacuations for some residents. A rock and mudslide also prompted the closure of Malibu Canyon Road, south of Piuma Road.

The winter storm is the second of three pushing through Southern California this week, bringing more rain and snow to an already soaked region and prompting the National Weather Service to issue a winter weather warning for Los Angeles County mountains.

Snow and hail was seen in Santa Clarita, La Habra, Rancho Cucamonga, Yucipa, Brea, Lancaster, Playa del Rey, Van Nuys and Granada Hills. 

But the more significant issue Wednesday afternoon was the wind. Strong gusts knocked down large trees in Northridge, Inglewood, Glendale, Brentwood and Laurel Canyon. No injuries were immediately reported due to any of the downed trees.

As California deals with the wrath of the winter storms, Governor Gavin Newsom issued a state of emergency for 13 counties, including Los Angeles and San Bernardino.

Los Angeles County health officials continued to warn people to avoid going into the ocean near discharging storm drains, creeks and rivers due to the storms. The water might contain bacteria, chemicals, debris, trash and other health hazards.

This weekend was the first time downtown Los Angeles received at least 2 inches of rain on consecutive calendar days, a first since Feb. 28 and March 1 of 1978, according to the NWS.

The weather service added that Friday was the wettest February day at Burbank Airport since records began there in 1939, beating the previous record of 4.50 inches set on Feb. 8, 1993.
