Rain fell on much of Los Angeles and Orange counties Monday, prompting a flash-flood warning for the Woolsey Fire burn area in Malibu.
The showers, expected to last through Tuesday, could bring up to 2 1/2 inches of rain in the San Gabriel Mountains and foothills, according to the National Weather Service.
Road closures as of 8:30 p.m. included:
— state Route 23 from Pacific Coast Highway to upper Mulholland Highway in Malibu;
— the truck lanes of southbound Antelope Valley (14) Freeway to the southbound Golden State (5) Freeway; and
— the connector from the , open to trucks only.
Trabuco Canyon Road at Trabuco Creek was closed due to a flash flood downstream of the Holy Fire burn area, Orange County Public Works announced. The department says the force of the fast-moving water moved k-rail barriers, which each weigh about 8,000 pounds.
The flash flood for the Woolsey Fire burn area warning expired at 11:45 a.m.
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,” weather service meteorologist Curt 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.
Winds reached 51 mph in the Santa Monica Mountains Recreational Area and 39 mph in the Santa Clarita Valley.
