A winter weather advisory means that periods of snow will make travel difficult. Among the areas included in the advisory were Cuyamaca, Mount Laguna and Ranchita.
“Residents and travelers into the mountains should be prepared for hazardous driving conditions due to slick roads,” an NWS advisory said. “If possible, carry chains and take extra food and clothing.”
As of 8 a.m., just over an inch of snow had accumulated at the 6,000-foot level on Mt. Laguna, one of the highest areas in the county. Snow plows had cleared the Sunrise Highway, but the roadway remained wet.
Mountain areas this morning were also subject to sustained southwest winds of 15 to 25 miles per hour and gusts up to 40 mph.
The mild storm brought less than half an inch of rain to coastal area, Fox 5 weathercaster Chrissy Russo said. It was the first measurable rain of the year for the parched county.
