More rain and snow forecast for Southern California through Thursday

by in News

More rain and snow is forecast for this week following a late-winter storm that brought a dusting of snow to Southern California mountains and scattered rainfall to lower elevations Tuesday, March 17, the National Weather Service said.

Another storm is expected Wednesday, with an early-morning winter weather advisory for Riverside and San Bernardino County mountains that will last late into the night, with precipitation going into Thursday.

Snow levels will be above 4,000 feet. Rain below that elevation in the mountains could be one to two-thirds of an inch, and locally higher the NWS said.

Rain amounts for Orange County and Inland valleys are expected to be a quarter-inch.

Los Angeles County will get more of a break between storms, with showers expected Thursday, although by then the system will be “moisture starved” from traveling over land, so rainfall is forecast to be minimal, the NWS said. Snow levels will be at 3,000 feet.

A 12-hour small-craft advisory will start at 11 a.m. Wednesday for coastal waters from San Mateo Point to the Mexican border.

Temperatures will be cooler across the entire region, then warming Friday and Saturday as the storm departs. But all of Southern California will likely get rain from yet another storm,  starting Sunday.

Forecast highs and lows for Wednesday include 63 and 48 for Los Angeles: 62 and 15 for Long Beach; 61 and 42 for Woodland Hills; 64 and 50 for Anaheim; 63 and 52 for Newport Beach; 60 and 45 for Riverside, and 59 and 45 for San Bernardino.

On Tuesday, snow showers were reported at Big Bear Lake and Lake Arrowhead and Green Valley Lake in the San Bernardino Mountains,  and across the San Gorgonio Pass in Idyllwild and Pine Cove in the San Jacinto Mountains, the NWS said.

The snow was light enough that chain controls for vehicles in the mountains that had been imposed overnight were lifted in the early afternoon by Caltrans.

Green Valley Lake in the San Bernardino Mountains had the most accumulated snow from the storm in the area, at 6 inches by late morning.

The San Gabriel Mountains also got a dusting of snow, including Mount Baldy, with Angeles National Forest officials asking the public to pick up after themselves if they visit the area.

Hail was reported in some areas, including Woodland Hills.

Rainfall was variable but mostly in small amounts in the valleys and lower elevations.
