The first of two storms expected to strike San Diego County this week arrived early today, bringing colder temperatures, light to moderate rain and gusty winds.
Rainfall totals from the first storm, which is expected to last through the day, will likely range from a third of an inch near the coast to one to two inches in the mountains, according to the National Weather Service.
The agency issued wind advisories for the mountains and deserts until 9 tonight and 3 a.m. Friday, respectively. During the advisory periods, 20- to 30- mile per hour west winds, gusting up to 50 mph, are likely, according to the Weather Service.
In addition to the mountain and desert wind advisories, a small craft advisory is in effect, prompted by gusty winds over coastal waters. It is set to expire at 9 a.m.
"Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these conditions,'' said an NWS advisory.
Another period of strong west winds is expected later this week. The Weather Service forecast that a second, somewhat stronger storm will likely arrive late Thursday or early Friday, lasting into Saturday.
The most significant precipitation will occur on Friday, the agency advised, noting total rainfall from the second storm will range from a quarter to a half-inch near the coast to one to two inches in the mountains.
Local snow levels will lower to 4,000 to 4,500 feet Friday, with four to eight inches of snowfall possible, mainly above 5,000 feet, according to the Weather Service.
