Gusty west-northwesterly winds, low afternoon relative humidity, and warming temperatures will elevate fire danger across interior northwestern California this weekend.
Breezy northerly winds are forecast along the coast Saturday. Gusts could reach 30-35 mph along most areas, with locally higher gusts on coastal headlands and exposed ridges. Interior areas could see gusts up to 30 mph as well.
