Wood fires will be banned in the Bay Area on Wednesday during a Spare the Air alert for poor air quality.

This will be the eighth Spare the Air alert called this cold season by the Bay Area Air Quality Management District since Nov. 1.

During alerts, the pollution district bans wood and other solid fuel fires in fireplaces, fire inserts, stoves or outdoor fire pits.

Air quality forecasters predict Wednesday will have unhealthy air caused by cold stagnant air that traps smoke and other fine particles near the ground.

The district regulates air pollution in seven Bay Area counties and southern parts of Solano and Sonoma counties.
