SAN DIEGO -- Gusty wind and potentially heavy rain are expected to pummel parts of San Diego County throughout the day Monday.
A National Weather Service wind advisory for the mountains and deserts is in effect until 10 p.m. Tuesday. Winds of 35 to 50 miles per hour are expected in most areas, but gusts could reach 50 to 75 mph over the mountain ridges and along desert slopes.
"Strong and gusty westerly winds will continue through Tuesday," according to the weather service. "Winds will be strongest along the mountain ridges, through mountain passes and into adjacent deserts."
Light rain began falling during the morning hours. As of 7 a.m., automated gauges collected .06 of an inch of rain in De Luz and on Mount Laguna; .04 in Julian; .03 at Lake Cuyamaca; .02 in Pine Hills; and .01 at Camp Pendleton, and in Del Mar, Descanso and San Marcos, according to NWS data. No measurable precipitation was reported in the deserts.
Anticipated rainfall amounts through Tuesday are expected to be .06 of an inch in Borrego Springs; .16 in San Diego; .28 in the Miramar area and Ramona; .32 on Mount Laguna; .33 in Oceanside; .34 in Escondido; .47 in Alpine; .98 in Julian; and 1.04 inches on Palomar Mountain, according to the NWS. The snow level will stay above 8,000 feet.
The rain may lead to slick roads with water ponding in some areas. The wind may also affect traffic through passes and along some desert highways, according to the weather service. Motorists were urged to use extra caution.
"Although rainfall will not be great, commutes could be wet and slow," according to the weather service. "Winds will be strong and gusty in parts of the mountains and deserts."
The rain is expected to taper off and the winds to weaken on Tuesday night. Forecasters said high pressure would bring fair and warmer weather Wednesday and Thursday, but another storm may deliver more rain Friday into next weekend.
Two inclement weather homeless shelters in downtown San Diego will open Monday.
Father Joe's Villages at 1501 Imperial Ave. has room for 250 people. Check-in begins at 4 p.m. and guests must be out by 5 a.m.

The shelters are opened during severe weather conditions, either 50 degrees or below or a 40 percent or greater chance of rain, according to the San Diego Housing Commission, which oversees homeless programs. In the city of San Diego, there is a 70 percent chance of measurable precipitation, according to the National Weather Service.
