Burning wood fires will be banned in the Bay Area on Tuesday during the third Spare the Air alert of the winter season.

The Bay Area Air Quality Management District forecasts unhealthy levels of smoke and other fine particulates on Tuesday because stagnant air will trap pollutants near the ground.

During the alert, it will be illegal to burn wood, wood products or other solid fuels in fireplaces, stoves or outdoor fire pits.
