Santa Ana winds will stir across San Diego County tonight into Thursday, and a second, more powerful windstorm is forecast going into the weekend, according to the National Weather Service.

A warm day is expected on Thursday for coastal areas with gusty northerly Santa Ana winds for late Wednesday night through Thursday, NWS said. Winds will likely subside Thursday night and Friday.

The agency said a stronger and more widespread Santa Ana wind event is expected across the area Friday night and Saturday.

San Diego County will likely see the strongest winds during the day Saturday as surface flow becomes more easterly. Wind gusts over 75 mph appear possible over the mountains, canyons and passes, NWS said. Winds are forecast to slowly lose strength across the area Saturday night and Sunday.

A very dry airmass will spread across Southern California this weekend and last through the middle of next week, with warm days and cool nights expected, according to the weather service.
