The Air District is issuing an air quality advisory due to wildfire smoke from the Pickett Fire for today, August 21, and tomorrow, August 22. Smoke from the Pickett Fire in Napa County is expected to impact Sonoma, Napa, and Solano counties on Thursday and Friday. Conditions can change rapidly and the amount and location of smoke at ground level is hard to predict. The public can check for real-time smoke pollution levels in their local area with the U.S. EPA’s Fire and Smoke Map. Smoky, hazy skies may be visible, and the smell of smoke is possible.
