LOS ANGELES (KTLA) — A very cold storm arrived in Southern California Tuesday, bringing rain, wind and snow, along with potential traffic headaches.

Driving conditions along the mountain passes were treacherous overnight and the stretch of Interstate 5 through the Grapevine was expected to be closed.

Most areas will see about one-third to two-thirds of an inch of rain, with up to an inch possible in the San Gabriel mountains.

There’s also a possibility of thunderstorms, with small hail and isolated waterspouts off the coast.

A winter storm watch will be in effect from Tuesday afternoon through Wednesday morning for the Ventura County mountains and Los Angeles County mountains.

There are also winter storm warnings for the Riverside County and San Bernardino County mountains.

Winter weather advisories have been issued for the valleys of the Inland Empire, the Santa Ana mountains and foothills and the Antelope Valley.

The snow level could drop as low as 1,500-2,000 feet, and icy roadways could force the closure of Interstate 5 through the Grapevine.

The winter weather could also impact Highway 14 from Soledad Canyon, Highway 33 in the Ventura mountains and Highway 138 through the Antelope Valley.

The L.A. County Public Works Department said it is planning closures for roads entering the Angeles National Forest starting at 3 a.m. Tuesday.

Some six to 10 inches of snow are expected above 4,500 feet, and three to six inches are expected between 3,000 and 4,500 feet.

One to three inches of snow are possible in the Antelope Valley foothills, and the Santa Clarita Valley foothills could get a light dusting.

The storm is also expected to bring high winds to many parts of Southern California.

A wind advisory is in effect from noon on Tuesday through early Wednesday for the Ventura county coast and valleys, as well as the Santa Clarita Valley.

Similar advisories have also been issued starting Tuesday afternoon for the Los Angeles County coast, the Orange County coast and the valleys of the Inland Empire.
