Smoke from those fires has severely impacted ambient air quality. As a result, the San Joaquin Valley Air Pollution Control District has re-issued a health caution due to the unhealthy levels of large particulate matter (PM) and PM2.5 (particles less than 2.5 microns in diameter).

The health caution will remain in effect until the fires are extinguished.

The District anticipates the air quality to be unhealthy throughout the weekend and has warned residents to stay indoors with all windows closed as a result. They also caution that the common cloth and paper masks worn by many to help reduce the transmission of the novel coronavirus may not be adequate protection from wildfire smoke.

Please exercise caution. Stay safe. Stay indoors.
