Widespread dense fog posed a threat to motorists in San Diego County's coastal and valley areas early Wednesday, as high winds were expected in the mountains and deserts Thursday.
The National Weather Service issued a dense fog advisory for the coastal and valley areas until 9 a.m., saying visibility was a quarter-mile or less, especially along portions of interstates 5, 805 and 15, and state Route 163.
"If driving, slow down, use low beam headlights and leave plenty of distance ahead of you,'' the NWS advisory said.
Meteorologists also said Wednesday strong, gusty winds were headed for the mountains and deserts of San Diego County this week.
NWS scheduled a high wind watch for the mountains and deserts from 3 a.m. Thursday to noon Friday, saying that by Thursday afternoon, 20 to 30 mile per hour sustained winds and gusts up to 55 mph were possible.
"Strong winds will make driving difficult, especially for motorists with high profile vehicles,'' an NWS advisory said. Watch for broken tree limbs and other debris on roadways.''
