National Weather Service(@NWS):Santa Ana winds will continue to impact southern CA through Saturday. Visit https://t.co/qk3BcVP5M8 for your latest local forecast updates! Santa Ana winds are strong downslope winds that blow through the mountain passes in Southern California. They are created over the Great Basin region from high-pressure air masses, which then blow down towards sea level. These winds, which can easily exceed 40 miles per hour, are warm and dry, and can severely exacerbate brush or forest fires, especially under drought conditions.
