SAN DIEGO — A winter storm warning is now in effect for San Diego County mountains until 6 p.m. Wednesday, the National Weather Service announced.

Forecasters say the cold low-pressure system from the north is expected to bring snow totals near one foot in parts of the higher terrain above 5,000 feet in the county.

Light scattered showers began Tuesday afternoon, with thunderstorms possible into Wednesday morning. A high wind warning also is in effect until 9 p.m. in the deserts while wind advisories expire at midnight in the inland valleys and coastal areas.

Rainfall will pick up intensity and become more widespread into the evening through Wednesday morning, according to the NWS.

“The trough’s east-west orientation continues to favor SD County for highest totals, where some places along the coastal slopes could receive over an inch of rain fall and coastal areas near one half inch,” forecasters said.

Several school districts in San Diego County canceled classes Tuesday due to weather, county education officials said. The NWS is advising drivers to be aware of hazardous travel, especially through the mountains.

Showers come to a gradual end on Wednesday afternoon as the storm begins to exit the region, according to forecasters. Dry, warm temperatures are expected to return Thursday and remain through the weekend.
