SAN DIEGO -- Sunday brought rain and snow to San Diego County, drawing crowds to mountain communities that gave way to traffic nightmares and road closures in the evening.
Four inches of snow fell in lower-elevation areas such as Julian overnight. The dusting began falling late in the afternoon and continued steadily into Monday morning, the National Weather Service reported. Six to 12 inches were recorded at Mt. Laguna and Palomar Mountain.
By 4 p.m. Sunday, the Sheriff's substation in Julian asked visitors to stay out of the town due to "large crowds" and snowfall. "Driving conditions continue to be dangerous due to the weather," the department explained on Twitter.

A series of accidents on the road to Julian slowed traffic to a crawl by 6 p.m. A short time later, California Highway Patrol announced a portion of State Route 79 -- from Mile Post Marker 7 south of Cuyamaca Lake to State Route 78 in Julian -- would be closed. Sunrise Highway was also closed from SR-79 to Old Highway 80.
The closures remained Monday morning.
Sheriff's officials said large crowds had also gathered in Mt. Laguna and other mountain areas. "Expect heavy traffic and windy/icy conditions over the coming days," the county's Rural Substations group warned on Twitter. "Be prepared and bring tire chains just in case. Be mindful of your surroundings."
"It’s pretty snowy up there," one driver told FOX 5 after driving down from Mt. Laguna. "A couple cars got stuck and then I heard a teen kid had to run in his sweatpants to one of the troopers to get help.”
Chain control requirements also went into effect near Mt. Laguna and Julian:
