A cold storm out of the gulf of Alaska will generate showers in the Southland and snow in the mountains before clearing out Saturday night, forecasters said.
The storm was some 500 miles to the west over the Pacific Ocean Friday morning and expected to slide into Southern California Friday evening, remaining through Saturday, said National Weather Service meteorologist Todd Hall.
Along with showers this evening, the storm is expected to produce 1-3 inches of snow in the San Gabriel Mountains at around the 5,000-foot level, far above The Grapevine, meaning no major impacts are expected over the Interstate 5 corridor, Hall said. At sea level, between a tenth and a quarter-inch of rain is expected while in the mountains, the storm could generate between a quarter and a half-inch of rain, he said.
As of Friday morning, no mud slides or debris flows are expected over burn areas, but that could change if a thunderstorm parks itself over slopes denuded by wildfire, Hall said, adding that the chance of thunderstorms is slight late Friday evening and Saturday morning.
