Once again, a pacific storm will bring the Southland periods of light to moderate showers Thursday, with up to 3 inches of rain possible in the San Gabriel Mountains and up to 2 inches at lower elevations, according to the National Weather Service.
And, just like on Wednesday, there’s a slight chance of thunderstorms Thursday afternoon, and these could generate brief, heavy downpours, small hail, and waterspouts.
In the San Gabriel mountains, the snow level will be at 7,500 feet, forecasters said.
The expected precipitation results from an upper low off the coast, said NWS meteorologist Curt Kaplan, adding that the storm, which originated in the Pacific, has been infused with tropical moisture. He said that most of Thursday’s rain will fall on the San Gabriels.
The low behind the current storm will start moving south Friday, according to Kaplan.
Another storm, this one a colder system originating in the Pacific northwest, will reach the Southland Sunday, Kaplan said
The NWS said the storm could cause roadway flooding and hazardous driving conditions, minor mud and debris flows over areas denuded by wildfires.
