LOS ANGELES, CA — Another storm will strike the Southland early Wednesday, creating flood risks throughout the region, according to forecasters. However, the weather system is not expected to be as cold or wet as last week’s rainstorm.
The fast-moving cold front will bring a period of heavy rain Wednesday that is expected to create a risk of flash floods. A flood watch will go into effect for all of Orange County Wednesday morning.
In L.A. County, the rain will start early Wednesday and last through Wednesday night, said NWS meteorologist Curt Kaplan. About a half-inch to an inch-and-a-half of rain is expected, Certain areas including the San Gabriel Mountains could see as much as three inches of rain, forecasters said.
The snow level is not expected to reach as low as it did a lasting week, shutting down holiday travel through the Grapevine. Mountain communities last week saw up to four feet of snow, and hundreds were snowed in up in Big Bear.
No snow-related disruptions on Interstate 5 through the Grapevine are expected this time around, Kaplan said, adding that there will be a “slight chance” of thunderstorms.
Forecasters said Monday that there was a chance of only minor mudslides or debris flows over slopes previously denuded by wildfire. But Kaplan said early Tuesday that forecasters will want to examine the latest computer models of the storm during daytime hours Tuesday before issuing updated forecasts.
Once they had, they concluded that there was a “low risk” of serious mudslides or debris flows, NWS meteorologist Tom Fisher said at 10 Tuesday morning.
