The first significant storm of the rainy season is expected to blow into San Diego County overnight, bringing chilly temperatures and some much needed rain through the weekend.
Rainfall is expected to total a half-inch along coastal and valley areas, and up to two inches in the mountains, with a dusting of snow above 6,000 feet.
"Precipitation should last until early Sunday," said Jimmy Taeger, meteorologist with the National Weather Service. "We’re going to see the brunt of it in San Diego County west of the mountains mainly Thursday into Friday."
Moderate to strong gusty winds are possible along the mountain ridge-tops, according to a NWS advisory. "Gusts could reach 60 mph or greater in favored spots," the agency stated.
Heavy rainfall in recently burned areas could cause mud and debris flows. Residents are urged to shelter in place or move to higher ground if they get caught up in a flash flood.
The first storm of the season also typically means hundreds of car accidents. The California Highway Patrol is warning roads are extra slick because of oils that have accumulated all summer. Motorists are advised to slow down and keep a safe distance from other vehicles.
The wet weather is a hopeful sign in what's been one of the driest calendar years on record; San Diego has received just 3.6 inches of rain since Jan. 1.
