A low pressure system from the Gulf of Alaska will bring strong winds to the mountains and deserts of San Diego County early Tuesday and a slight chance of rain to the western parts of the region, forecasters said.
The National Weather Service issued a wind advisory for the mountains and deserts until 8 a.m., saying wind gusts of up to 65 miles per hour were possible near mountain ridge tops, along desert mountain slopes and into adjacent desert areas.
Elsewhere in the mountain and desert areas, sustained winds of 20 to 30 mph and gusts of 55 mph are expected.
"The winds will make driving difficult, especially for motorists with high profile vehicles," the NWS said. "Watch for broken tree limbs and other debris."
The weather service said overall precipitation totals Tuesday will be light, with the coast and inland valleys seeing less than 0.15 inches of rainfall.
"The best chance of showers during the morning commute will be over western San Diego County," the NWS said, adding drier weather is in the forecast for this afternoon and evening before a second round of rain arrives Wednesday morning.
