LOS ANGELES — Showers will turn into steady rain Monday morning, with another half-inch to 1 1/2 inches of rain expected in the Los Angeles area before showers return this evening, lasting through Tuesday, a National Weather Service meteorologist said.
Riverside is expected to get a half-inch to an inch of rain, but Lake Elsinore is forecast to be hit with an inch to an 1 1/2 inches. Orange County is expecting a half-inch to an inch, and Inland Empire communities should see an inch to 1 1/2 inches.
This morning’s showers were in advance of a new band of rain from the storm, which will make itself felt mid- or late Monday morning, NWS Meteorologist Curt Kaplan said. There could be up to 2 1/2 inches of rain in the San Gabriel Mountains and foothills.
Cooler temperatures accompanied the precipitation, leading to possible snowfall in the Grapevine area late Monday into early Tuesday and “maybe even a dusting in the Antelope Valley foothills,” Kaplan said.

The San Gabriel Mountains could see 8 to 16 inches of snowfall above 6,500 feet before the system moves out, he said.
The showers should move out late Tuesday into Wednesday, with the next chance of rain Friday evening into Saturday, Kaplan said.
Temperatures along the coast could range from highs in the mid-50s to 60 Monday and lows in the mid-40s to low 50s down to highs Tuesday in the low to mid-50s, he said. Similar highs are forecast for inland and valley areas, but lows could drop to the mid-to-upper 30s.
Along the coast, a high surf advisory remained in effect in Los Angeles and Orange counties until 11 a.m. Monday, forecasters said.
The NWS also issued wind advisories through 3 p.m. Monday for the Malibu area, including Kanan, Malibu Canyon, Topanga and Decker Canyon roads, and until 9 p.m. for the Antelope Valley including Lancaster and Palmdale. South to southwest winds 20 to 30 mph are possible with gusts to 50 mph expected to develop starting Monday morning. Motorists are urged to be prepared for sudden gusty cross winds.
