The Pacific storm that’s been hanging over the Southland since Monday will serve up a wet morning commute Friday before finally catching the jet stream and gliding out of the region, forecasters said.
“Sometimes, with a cutoff low, a storm just wobbles in place until it gets picked up by a jet stream,” and that will happen later this morning, National Weather Service meteorologist Dave Bruno said in a telephone interview from his monitoring station in Oxnard.
Rain is expected in Ventura County and Western L.A. County until it sweeps across the San Fernando Valley and exits in an easterly direction late this morning, Bruno said, although “a lot of low-level moisture” will persist through the weekend, producing some rainfall this afternoon.
Bruno said the length of time this week’s Pacific storm has been hanging around is not unheard of, but this was one of the “slower” systems to hit the Southland.
No debris flows or mudslides are expected Friday, even over areas previously denuded by wildfire, “but we came close on Thursday” when the rain began to fall at a rate of three-quarters of an inch an hour outside the Saddleridge burn area south of the Santa Clarita Valley.
Another storm system will blow into the Southland late Monday, and this one could douse the San Gabriels at lower elevations, including The Grapevine.
The weather service forecast showers on Friday and highs of 46 on Mount Wilson; 58 in Saugus; 59 in Avalon; 60 in Palmdale, Lancaster, Pasadena and Burbank; 61 in San Gabriel and Woodland Hills; 62 in Long Beach; and 63 in Downtown L-A and at LAX. Showers are expected tomorrow along with roughly the same highs as today, followed by a mostly cloudy Sunday and a rainy Monday, Tuesday, Wednesday and Thursday.
Showers were also forecast in Orange County, along with highs of 43 on Santiago Peak; 51 on Ortega Highway at 2,600 feet; 56 at Fremont Canyon; 58 at Trabuco Canyon; 60 in Yorba Linda and Laguna Beach; 61 in San Clemente and Mission Viejo; 62 in Newport Beach, Fullerton and Anaheim; and 64 in Irvine.
More showers were forecast Saturday along with slightly higher temperatures, followed by cloudy skies Sunday and Monday, then more rain and showers through Thursday.
