  • Air District issues air quality advisory for Sunday
    Air District issues air quality advisory for Sunday

    The Air District is issuing an air quality advisory for wildfire smoke for Sunday, August 20. Smoke from numerous fires in northern California is impacting air quality over far northwestern California. Wind patterns are helping to keep smoke away from the Bay Area today through most of the day on Sunday. However, some smoke is predicted to reach the North Bay by late Sunday afternoon, causing air quality to reach low-Moderate on the U.S. EPA’s Air Quality Index. Smoky, hazy skies may be visible in the North Bay and the smell of smoke is possible at higher elevations. Pollutant levels are NOT expected to exceed the national 24-hour health standard and there is no Spare the Air Alert in effect.
