Incidents and Advisories

Learn about air quality incidents in the Bay Area, and view advisories and preliminary incident reports.

Occasionally, a significant air pollution event occurs in the Bay Area. As soon as sufficient information is available, the Air District prepares an advisory or a preliminary incident report.

A preliminary incident report provides an early overview of the incident but is not a substitute for the in-depth investigation that follows. Incident reports in the table below are listed in chronological order.
