Downtown Los Angeles received more than an inch of rainfall late Monday night through Tuesday as the heaviest rain drenched the metropolitan area, according to an interactive map from the Ventura County Public Works Agency. Higher totals were recorded in some locations, including the San Gabriel Valley, foothills and mountains.

Snowfall of 2 to 5 feet is forecast at elevations of 6,000 feet and higher. Slightly lower elevations, from 3,500 to 5,000 feet are expected to get between 2 to 10 inches of snow, prompting winter storm warnings for the mountains of San Bernardino and Riverside counties until 5 a.m. Thursday. 

The NWS also issued a winter storm warning for areas of the Interstate 5 Corridor and the Highway 14 Corridor through the San Gabriel Mountains. CHP was escorting traffic through Interstate 5 along the Grapevine due to snow Tuesday afternoon and evening.  

Hazardous marine conditions are also forecast. Seas as high as 8 to 14 feet are possible through Wednesday. Coastal areas could see minor flooding with surf ranging from 7 to 13 feet.
