A cold, blustery storm originating from the Gulf of Alaska is expected to move down the California coast Tuesday, creating traffic headaches in some places, authorities warned.

Possible thunderstorms were expected to affect most of the Southland, bringing between one-tenth to half an inch of rain in most areas, the L.A. Times reported.

Snow could fall as low as 1,500 feet, and there was high potential for icy roadways, including Interstate 5 from the Grapevine to the Santa Clarita Valley, according to the National Weather Service.

In the tri-city region, thunderstorms on Tuesday could produce small hail.

Highway 14 through Soledad Canyon and Antelope Valley, Highway 33 in the Ventura mountains and Highway 138 through the Antelope Valley might also be difficult to pass, according to the National Weather Service.

With a storm on the way, Los Angeles County officials warned of likely closures on roads leading into the Angeles National Forest shortly after midnight Monday.

Even as the storm starts to break up on Wednesday, there will be a slight chance of showers through Thursday. Expect partly cloudy skies and cool temperatures through Sunday, according to the weather service.
