Because of the build-up of high pressure, lighter winds, and deteriorating dispersion conditions, smoke from the fire may affect air quality in the central and southern San Joaquin Valley through the weekend.

The smoke contains particulate mater (PM2.5) that can cause serious health problems including lung disease, asthma attacks, and may increase the risk for strokes and heart attacks. Those people with existing respiratory conditions, young children, and the elderly may be particularly impacted by these conditions.

The SJVAPCD urges residents to follow their doctor's orders when exposed to PM2.5 and to stay indoors if possible, particularly if they can smell smoke or see ash in the sky.
