SAN DIEGO (CNS) - Rain could fall up to the elevation of Pine valley, and snow might dust Julian and higher points, as a low pressure system moves toward the County, forecasters said Sunday.
The National Weather Service issued a winter weather advisory starting at midnight and expiring at noon Monday. The NWS expected rain to turn to snow early Monday at about the 4,500 foot level, which includes Cuyamaca, Mount Laguna and Ranchita.
And snow could dust Interstate 8 in East County early Monday,as the snow level drops to 4,000 feet, the NWS said. That would indicate possible snow at Julian, elevation 4,226, but not at Pine Valley, elevation 3,736.
"A colder low pressure system from the northwest will move across the Southern California coastal waters and adjacent land areas for tonight and Monday bringing showers and a slight chance of thunderstorms," the NWS advisory said.
Forecasters expected showers to increase late tonight with the most significant of them and a slight chance of thunderstorms Monday morning.
Less than 2 inches of snow was expected to fall below 4,500 feet, according to the NWS. Above that contour, 2-4 inches could accumulate in higher elevations.
Southwest winds of 15 to 25 mph with gusts to 40 mph were also possible.
Meteorologists said blowing snow and fog could reduce visibility at times and said mountain residents and travelers should be prepared for hazardous driving conditions and slick roads. Motorists are advised to carry snow chains, along with extra clothing and food.
