Afternoon thunderstorms possible if a winter storm is approaching

SAN DIEGO — A winter storm bringing strong winds, cool temperatures, widespread rain and snow in the mountains is expected to make landfall in San Diego County Tuesday afternoon and continue through Wednesday morning, according to the National Weather Service.

Forecasters are predicting light showers to begin Tuesday afternoon, with a chance of thunderstorms from afternoon through Wednesday morning. Winds could also get strongest in the afternoon, reaching at times gusts of over 30mph near the coast and over 80mph in the mountains and deserts.

As the day progresses, meteorologists expect the rains to increase in intensity, spreading further into the evening and Wednesday morning.

A winter storm warning for the mountains of San Diego County is in effect Tuesday 4 p.m. through Wednesday 6 p.m.

“The east-west orientation of the trough continues to favor SD County for the highest totals, where some locations are located
along coastal slopes rain could fall over an inch and coastal areas nearly half an inch,” forecasters said.

The cold depression is coming from the north, the NWS said. Total snowfall is expected to be about a foot in parts of the higher terrain above 5,000 feet in San Diego County.

Several school districts in San Diego County canceled classes Tuesday due to the weather, district education officials said. The NWS advises drivers to be aware of dangerous journeys, especially through the mountains.

Showers will gradually end on Wednesday afternoon, forecasters say, as the storm begins to leave the region. Dry, warm temperatures are expected to return on Thursday and continue into the weekend.
