Wildfire Smoke Impacts Sacramento Region
Smoke from several wildfires burning in Northern California is impacting the Sacramento region, enhancing ozone formation and increasing particle concentrations. Air quality can change quickly at different times during the day due to wind shifts and vertical mixing. If you see or smell smoke in your area you should stay indoors and avoid outdoor activities.

Air Quality Forecast and Weather Discussion
Tuesday, light westerly winds will limit dispersion and gradually bring wildfire smoke into the Sacramento region. As a result, particle levels will be Unhealthy for Sensitive Groups, and ozone levels will be mid- to high-Moderate. Wednesday and Thursday, northwesterly winds will develop each afternoon, increasing mixing and dispersion. However, these winds will transport additional smoke into the Sacramento region, keeping particle levels Unhealthy for Sensitive Groups on both days. Ozone levels will be Moderate on both days.
