A spring storm is expected to bring cooler weather, gusty wind, rain and possibly thunderstorms and mountain snow to the San Diego region starting this weekend.

Sunday is forecast to be the day with the most widespread and heaviest rain, according to the National Weather Service. Drivers should prepare for rain-slicked roads with wind-toppled trees.

Scattered light showers and drizzle is expected to start Saturday morning and afternoon in the mountains, said forecasters. Numerous showers and possible thunderstorms will pour on Saturday night through Sunday.

Isolated pockets of rainfall will continue Monday and Tuesday, with showers tapering off by Wednesday afternoon.

Small-stream floods are expected to cause driving hazards from brief yet heavy rain showers across San Diego.

Temperatures will turn cooler Friday, with patchy morning fog and highs only 68 to 73 along the coast and 70 to 75 inland.

The approaching low-pressure system will cause high temperatures to fall to 15 to 25 degrees below average on Sunday.

Light rain may begin falling in some areas as soon as Saturday morning, and strong winds are expected to sweep into the region Saturday afternoon, according to the National Weather Service.

A wind advisory for the mountains and deserts will begin at 2 p.m. Saturday and extend until 2 a.m. Sunday. Winds are expected to ramp up to 20 to 30 miles per hour with gusts of up to 55 mph in the most affected areas and isolated gusts up to 65 mph by Saturday afternoon.

Strong wind will pass through the coastal waters, mountain ridges, desert slopes, passes, canyons and the deserts of San Diego, Riverside and San Bernardino counties.

Forecasters say the strong winds will blow dust and sand in parts of the desert that create dangerous driving conditions, especially for high-profile vehicles.

A slight chance of thunderstorms is in the forecast from Saturday night through Monday. It’s possible in all areas ranging from the coast to the deserts.

Icy hail may also fall with the thunderstorm, warned weather service forecasters.

The snow level is expected to drop to around 5,000 feet Sunday morning and a few inches could accumulate on higher peaks. Chain restrictions in the mountains are possible, due to the hazardous driving conditions.

Forecasters said the storm could drop 1 to 2 inches of precipitation in the mountains, half an inch to an inch of rain in coastal areas and a quarter-inch or less in the deserts. Showers may continue through Tuesday.
