Gusty winds are expected to develop Thursday in the mountains and deserts of San Diego County ahead of a trough of low pressure that will change their direction.
A National Weather Service wind advisory for the mountains and deserts will extend from noon today and through 2 a.m. Friday. West winds of 15 to 25 miles per hour with gusts of 45 to 50 mph will be possible this afternoon and tonight.
Forecasters said the winds begin to shift northeast tonight, starting a period of which will usher in Santa Ana conditions that will continue through Tuesday with the strongest winds Sunday and Monday.
“Strong westerly winds are expected in the mountains and deserts through tonight,” according to the weather service. “High pressure aloft and dry offshore flow will bring much warmer weather Friday through next week.”
The weather service also warned that the winds could wreak havoc on mountain and desert roadways, especially for motorists in high-profile vehicles. Visibility may also be reduced in the deserts by blowing dust and sand.
Although critical fire weather conditions are expected in much of Southern California later this week, forecasters said the recent rain would delay that in San Diego County. No upcoming fire weather warnings for San Diego County have been announced.
