Spare The Air Alert in Effect Tuesday, August 16, 2022
A Spare The Air alert has been issued for Tuesday, August 16, 2022. An upper-level ridge of high pressure will strengthen over northern California, reducing atmospheric mixing and producing sunny skies with temperatures near 105F. Furthermore, smoke from the Six Rivers Complex will impact the region. These conditions will enhance ground-level ozone formation. In addition, calm to light southwesterly winds will reduce dispersion, allowing pollutants to accumulate in the Sacramento area. As a result, ozone levels will be Unhealthy for Sensitive Groups.

Air Quality Forecast and Weather Discussion
Tuesday is a Spare The Air Day in the Sacramento region. An upper-level ridge of high pressure will reduce atmospheric mixing and produce sunny skies with temperatures near 105F. Furthermore, smoke from the Six Rivers Complex Fire will impact the region, enhancing ground-level ozone formation. In addition, a light delta breeze will reduce dispersion, allowing pollutants to accumulate in the Sacramento area. As a result, ozone levels will be Unhealthy for Sensitive Groups. Wednesday and Thursday, hot conditions will persist, supporting ozone production. Furthermore, light onshore winds early each day will continue to limit pollutant dispersion. Therefore, despite moderate onshore winds dispersing pollutants each afternoon, ozone levels will remain Unhealthy for Sensitive Groups on both days.
