Rising ozone levels throughout the San Joaquin Valley are causing air quality to deteriorate, and local air officials urge residents to take health-protective measures where necessary.
Typical summer meteorological conditions are ideal for ozone (smog) formation, which officials expect to continue through Thursday.
Residents can stay informed about air quality in their area through the Real-Time Air Advisory Network - a free, automated data delivery service that links the subscriber's computer to an air monitor of choice.

"This is, unfortunately, typical summer air quality in the Valley. Folks need to take precautions to protect their health, and to take steps to reduce their emissions," said Jaime Holt, the air district's chief communications officer.
Ozone is created when emissions "cook" in heat and sunlight, and peaks during late afternoon and early evening hours. It can exacerbate conditions such as asthma and cause symptoms including sore throat, cough and fatigue.
Residents can reduce smog-forming emissions by:
• Refraining from idling their vehicles
• Carpooling, vanpooling or alternate transportation
• Refraining from using drive-through services
