San Diego County will be under inclement weather through Sunday morning, with rain, wind and snow expected throughout the region.
The National Weather Service office in San Diego said a pair of low pressure systems will track over Southern California, preceded by a cold front, generating a variety of atmospheric activity.
A winter weather advisory is in effect until 2 a.m. Sunday, applying to locations above 4,500 feet initially.
“A line of moderate showers is likely to accompany the front, along with a chance of a few thunderstorms,” according to a weather service statement. “The front will sweep rapidly inland before sun-up, but cold, unstable conditions will persist over SoCal, continuing scattered showers and isolated thunderstorms through about midday Friday.”
The San Diego metropolitan area is likely to receive a quarter- to a half-inch of precipitation Thursday night and Friday morning, with a tenth to a quarter-inch possible Friday afternoon and evening, meteorologists said. Another tenth of an inch is in the forecast for Saturday.
Encinitas recorded .83 inches of rain as of 2:30 a.m., according to the weather wervice. Sylvan Meadows recorded .51 inches of rain and El Camino Del Norte recorded .42 inches of rain.
Quarry Road in Springs Valley was closed from Elkelton Place and State Route 125 because of flooding, according to the San Diego County Department of Public Works.
Flooding was also reported in lanes of Interstate 5 near the State Route 15 north exit toward Riverside.
“Snow accumulations of 8 to 14 inches above 7,500 feet, 6 to 8 inches from 6,500 feet to 7,500 feet, 4 to 6 inches from 5,500 to 6,500 feet, and 2 to 4 inches from 4,000 to 5,500 feet are expected,” the weather service stated.
Winds are likely to average 25 to 35 mph as the front scoots east, with gusts as high as 60 mph in some locations, mostly mountains and passes, though the Coachella Valley will be impacted as well, forecasters said.
The next trough of low pressure will dive south from the Pacific Northwest Saturday, further lowering snow levels to 3,500 feet.
“The inside track of this (second) storm will greatly limit valley precipitation amounts, but snowfall could still be very impactful over the mountains,” the weather service said.
High temperatures in the San Diego metro area Friday are expected to hover in the near 60, with lows in the low 50s.
A warming trend will begin Monday and last through the week, along with generally dry conditions.
