San Diego County should brace itself for wind gusts as strong as 65 mph in some areas Thursday, according to a National Weather Service report on Wednesday.
The warning projects powerful onshore winds in local mountains and deserts from 6 a.m. to 10 p.m. with gusts at their strongest Thursday afternoon and evening before gradually decreasing through the late night.
The cold, low-pressure system is moving southward along the West Coast.
Its strongest winds are anticipated on mountains' desert slopes and adjacent desert areas, ranging from 30 to 40 mph in wind speed with up to 65 mph gusts.
Visibility will be near zero at those desert regions due to blowing dust and sand, the NWS reported, and driving conditions will be difficult, especially for high-profile vehicles.
A less severe wind advisory will continue from 10 p.m. Thursday to 3 a.m. Friday.
