LOS ANGELES – After days of above-average temperatures, Southern California is about to be hit by a potent storm that will bring cooler temperatures, widespread rain, gusty winds, mountain snow, and high surf to the region.
What we know:
Forecasters at the National Weather Service (NWS) say temperatures could drop by as much as 20 degrees from Tuesday to Friday as a powerful storm makes its way to the area.Â
An atmospheric river will hit Northern California, and the impacts from that storm will then push southward into Southern California.Â
NWS models indicate wet weather will strike San Luis Obispo and Santa Barbara counties by as early as Wednesday night. By Thursday morning, it will move into Ventura, Los Angeles, Riverside, San Bernardino, and Orange counties.Â
The storm is forecast to be cold enough to bring snowfall to mountain areas at elevations as low as 6,000 feet. In addition, mud and debris flow in and around recent burn scar areas in Santa Barbara, Ventura, and Los Angeles counties could occur.
