There is an Air Alert in effect for the San Joaquin Valley through Friday, September 11.
An Air Alert is a notification that the Valley is currently experiencing conditions that may lead to exceeding a health-based ozone (smog) standard. Air Alerts are issued Valley-wide.
In addition to the negative effects on our health, ozone exceedances can also result in monetary penalties to the Valley. This would impose severe financial burdens on Valley businesses and, ultimately, our residents.
When an Air Alert is called by the Air District, Valley residents and businesses are advised to put into place measures that reduce vehicle use. These can include carpooling, vanpooling, using alternative transportation, avoiding the use of drive-through services and refraining from vehicle idling.
An Air Alert episode may last anywhere from several hours to several days.
