SAN DIEGO — A cold low pressure system crept into San Diego County early Friday, bringing gusty winds and light rainfall that was expected to intensify throughout the day.

Spotty showers will continue through the day with a second front hitting San Diego Friday eveninig, FOX 5 weathercaster Chrissy Russo said. In all, the region can expect 0.25 to 0.50 inches of rain west of the mountains before the front moves out on Saturday, Russo said.

The National Weather Service issued a wind advisory for the deserts and a winter weather advisory for the mountains from 3 o’clock Friday morning to 3 a.m. Saturday. A coastal flood advisory was scheduled until 10 a.m. Saturday.

During the wind advisory period, sustained west winds of 25 to 35 miles per hour — gusting up to 55 mph — were expected in the deserts.

In the mountains, snow levels around 4,500 feet Friday morning were expected to fall to around 3,000 to 3,500 later in the day and to 2,500 feet overnight. Also, sustained winds of 15 to 30 mph were expected to cause blowing snow in the mountains Friday, reducing visibility to a quarter-mile or less at times.

The heaviest snow is expected Friday before dark, according to the NWS. The agency said 4 to 8 inches of snow accumulation is likely above 4,000 feet, and up to 10 inches is possible on higher elevated coastal slopes.

“Slick, snow covered roads and reduced visibility will make travel hazardous through the mountains,” an NWS advisory said. “Chains may be required for some roads.”

Rainfall amounts from the storm are expected to range from up to a half- inch in coastal and valley areas to up to an inch in the mountains. There is a slight chance of thunderstorms and small hail this afternoon and evening, according to the weather service.
