The National Weather Service issued a 24-hour winter storm warning for mountain areas above 4,000 feet starting at 10 p.m. today.

During the warning period, four to eight inches of snow accumulation is expected between 4,000 and 6,000 feet, while six to 12 inches of snow accumulation is expected at and above 6,000 feet.

Mountain areas also will be buffeted by winds of between 15 to 25 miles per hour gusting at up to 40 mph between late tonight and Friday night, according to the weather service.

“Travel will be hazardous due to slippery roadways and poor visibility in heavy snow, blowing snow and fog,” according to an NWS advisory that warned motorists to be particularly careful along Interstate 15 through the Cajon Pass.

In addition to snow, the mountains are expected to receive an inch to an inch-and-a-quarter of rain from the low-pressure system.

Valley areas will see a quarter to a half-inch, with up to three-quarters of an inch in some spots, according to the weather service.

Isolated thunderstorms accompanied by small hail are possible Friday, along with brief, heavy downpours. NWS forecasters said.

“The precipitation will taper off late Friday night with a few lingering showers into Saturday,” according to an NWS advisory.
