Wildfire Smoke Impacting the Sacramento Region
The Sacramento region is currently experiencing smoke impacts from fires in southwestern Oregon and Northern California. Smoke impacts are expected from Wednesday, September 20 through Saturday, September 23, resulting in AQIs that are "Unhealthy for Sensitive Groups." Children, pregnant women, older adults, and those with certain medical conditions are especially vulnerable. If you see or smell smoke, go indoors and keep the doors and windows closed.

Air Quality Forecast and Weather Discussion
Saturday, light southwesterly morning winds will continue to circulate smoke throughout the Sacramento region from the Bay Area. However, as an upper-level trough of low pressure approaches northern California, atmospheric mixing will increase. Furthermore, strengthening afternoon winds will aid dispersion. These conditions will lead to mid-Moderate particle levels and low-Moderate ozone levels. Sunday, as the trough of low pressure nears northern California, moderate onshore winds will continue to disperse pollutants and bring cleaner air into the Sacramento Valley. As a result, particle levels will be low-Moderate, and ozone levels will be high-Good. Monday, moderate onshore winds will continue to transport cleaner air into the Sacramento region. In addition, partly cloudy skies and cooler temperatures will decrease ozone formation as the trough aloft moves inland over northern California. Therefore, particle levels and ozone levels are expected to be high-Good.
