A storm from Canada brought the Southland showers overnight, triggering a mudslide in Sherman Oaks and creating winter-weather conditions in the San Gabriel Mountains, authorities said Monday.
In addition to on-and-off showers Monday morning, there’s a chance of showers Monday afternoon, said National Weather Service meteorologist Todd Hall. Tuesday should be mostly dry, ahead of another system Wednesday night into Thursday. That system could drop snow on The Grapevine Thursday morning, but snow will not affect Interstate-5 Monday, according to the NWS.
The mudslide in Sherman Oaks occurred sometime before 10 p.m. Sunday in the 15000 block of West Hamner Drive. Debris damaged at least one residence, but no injuries were immediately reported.
In the San Gabriel Mountains, a winter weather advisory, which denotes challenging traveling conditions, will be in effect until 1 p.m. Monday.
“Moderate snow accumulations are expected over the higher elevations, which will affect the higher mountain roads,” according to an NWS statement. For now, “the snow will not affect Interstate 5.”
An accumulation of 6-10 inches of snow is expected above 6,500 feet, and less snow is expected between 4,500 and 6,500 feet, according to the statement.
Also expected in the mountains are southwest winds of 15-30 mph and 45-mph gusts, according to the NWS.
The heaviest snow will fall early Monday and until p.m, when the winter weather advisory will expire.
“Travel could be very difficult over higher mountain roads,” warned the NWS statement.
The NWS forecast rain Monday and highs of 42 on Mount Wilson; 58 in Saugus; 59 in Palmdale and Lancaster; 61 in Burbank; 62 in Avalon, Pasadena and Woodland Hills; 63 in San Gabriel; 64 in Long Beach 65 at LAX; and 66 in Downtown L.A. Tuesday and Wednesday will be mostly cloudy; and showers are forecast Thursday before two partly cloudy days amid temperatures ranging from the low 60s to the low 70s.
Partly cloudy skies are expected in most of Orange County, though the Santa Ana Mountains will experience showers, along with highs of 41 on Santiago Peak; 51 on Ortega Highway at 2,600 feet; 57 at Fremont Canyon and Trabuco Canyon; 59 in Laguna Beach; 60 in Yorba Linda and San Clemente; 61 in Newport Beach and Mission Viejo; 62 in Anaheim; and 63 in Fullerton and Irvine. Temperatures will remain about the same until a warming trend Saturday and Sunday, with showers forecast Thursday.
