The county Department of Environmental Health on Friday night issued a general advisory for the coastal waters amid the latest storm.
“Activities such as swimming, surfing and diving should be avoided in all coastal waters for 72 hours following rain,” the county said. “This includes all coastal beaches and all of Mission Bay and San Diego Bay.”
The county said elevated bacteria levels can persist after a rainstorm depending upon the intensity of the storm, volume of runoff and ocean and current conditions.
A spring storm packing a cold, wintry punch moved over the San Diego area Friday, bringing rain, high winds and potential for widespread late-season mountain snowfall.
The arriving bands of dark clouds began generating scattered late-morning drizzles in the northern reaches of the county, according to the National Weather Service.
The brunt of the system was due to arrive by late afternoon, said weather service meteorologist Mike Watkins.
Rainfall totals were expected to reach anywhere from about a half-inch or less to more than 2 inches across the region, while snowfall predictions ranged from 1 to 4 inches around the 4,000-foot level, 3 to 6 inches between 4,500 and 5,000 feet, and 6 to 10 inches above 5,000 feet.
Communities likely to get dustings or drifts of frozen white flakes included Boulevard, Cameron, Campo, Cuyamaca, Descanso, Julian, Lake Henshaw, Morena Village, Mount Laguna, Oak Grove, Pine Hills, Pine Valley, Ranchita, Santa Ysabel and Warner Springs, according to forecasters.
In the East County deserts, sustained winds up to 35 mph and gusts
reaching 60 mph were expected through late Saturday morning.
The storm also was expected to create heavy seas and potential for ocean waterspouts, prompting the weather service to issue a small-craft advisory through Saturday evening.
Here are the rainfall totals for San Diego County as of 5:05 p.m., according to the Weather Service.
