Up to 1 foot of snow expected to fall in the San Diego mountains

The latest in a series of Pacific storms will blow into San Diego County on Sunday where it will drop 8 to 12 inches of snow in the mountains and an inch or two in Julian by early Monday.

The National Weather Service says the storm also will produce up to one quarter-inch of rain at and near the coast, and about a half-inch across inland valleys and foothills.

The system is far colder than the “atmospheric river” that brought record rain to the county on Thursday. Snow could fall to the 3,500 foot level late Sunday as the cold front passes through.

Forecasters say the storm could affect traffic on Interstate 8, east of Alpine. The system also will produce hazardous driving conditions in the Cajon Pass.

The leading edge of the storm could bring snow to the mountains by 10 p.m. on Saturday. But the brunt of the system is expected on Sunday, with the heaviest snow in the latter part of the day.

A winter storm warning will be in effect for the mountains from 2 p.m. Sunday to 6 a.m. Monday.

Through Saturday morning, San Diego International Airport has received 10.25 inches of rain since the rainy season began on Oct. 1. That’s 4.01 inches above average.
