Cold, fast-moving storm bringing rain, snow to Southern California

by City News Service

LOS ANGELES — A cold, fast-moving storm out of the Gulf of Alaska worked its way Tuesday toward Southern California, where it was poised to hit Thursday and generate between three and five hours of moderate rain but is not expected to trigger mud slides or debris flows in burn areas, National Weather Service forecasters said.

In the San Gabriel Mountains, 4 to 8 inches of snow will fall above 5,500 feet and between 1 and 4 inches between 3,500 and 5,500 feet, said NWS meteorologist Rich Thompson in a telephone interview from his base in Oxnard in Ventura County.

South winds of 40 to 50 miles per hour and strong cross winds are expected over icy, snow-covered roads in mountain areas, causing blowing snow and sharply limiting visibility, warned the NWS, adding that the roads expected to be affected by challenging conditions include Interstate 5 through the Grapevine, the 14 Freeway, Pearblossom (138) Highway, and Highway 33 in Ventura County.

He said three to five hours of rain is expected Thursday and Thursday night, likely generating some minor urban flooding, although mud slides and debris flows over slopes denuded by wildfires are not expected.

“At this point, no problems are anticipated in burn areas,” he said early this morning.

Between a quarter-inch and three-quarters of an inch of rain are expected along the LA County coast and in the county’s valleys, and between three-quarters and 1 1/2 inches in the mountains and foothills, according to the NWS.

Similar conditions are expected in Orange County Thursday, with a quarter inch of rain near the coast starting late in the day, between a half-inch and an inch in the Santa Ana Mountains, and no problems expected in the burn areas of Orange and Riverside counties, NWS meteorologist Greg Martin said from his monitoring station in San Diego, describing the approaching system as “smaller” and “fast-moving.”

The NWS forecast sunny skies in LA County Tuesday, along with highs of 51 on Mount Wilson; 58 in Lancaster; 60 in Avalon, Hawthorne and Torrance; 61 in Long Beach, Santa Clarita, Burbank and at LAX; and 63 in downtown LA, Pasadena, San Gabriel, Sherman Oaks, Van Nuys and Woodland Hills. Wednesday’s temperatures will be about the same in some communities and slightly higher in others amid a combination of sunny and partly cloudy skies, but Thursday’s highs will dip to the low and high 50s amid rain before rising to the 60s on Friday.

The NWS also forecast sunny skies in Orange County Thursday and highs of 49 on Santiago Peak; 53 on Ortega Highway at 2,600 feet; 56 in Fremont Canyon; 57 in Laguna Beach; 59 in Trabuco Canyon and San Clemente; 60 in Newport Beach, Yorba Linda and Mission Viejo; and 62 in Fullerton, Anaheim and Irvine. Wednesday’s temperatures will be about the same or slightly higher, still under sunny skies, but Thursday’s highs will be unchanged in some communities but several degrees lower in others bore reverting to roughly Wednesday’s levels under sunny skies.
