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
Friday, periods of calm winds will limit pollutant dispersion, while sunshine and temperatures in the low-80s will aid ozone formation. However, light onshore winds in the late afternoon and evening will aid dispersion, and pollutant carryover from the previous day will be low. Therefore, particle and ozone levels will be Good. Saturday, light to moderate onshore winds will aid dispersion, while cooler temperatures will hinder ozone formation. As a result, particle and ozone levels will remain Good. Sunday, as a strong cold front moves across the Sacramento Valley, gusty northwesterly winds will aid dispersion. However, these winds will also produce isolated areas of blowing dust. These conditions will yield low-Moderate particle levels and Good ozone levels.
