Air quality in the Bay Area is forecast to be unhealthy again Wednesday so another "Winter Spare the Air Alert" will continue tomorrow.
It will be illegal for Bay Area residents to burn wood or other solid fuels in fireplaces, wood stoves and inserts, pellet stoves, outdoor fire-pits, or other wood-burning devices both indoors and outdoors for the full 24 hours.
This wood-burning ban will be in effect for Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, southern Sonoma and southwestern Solano Counties.
Winter air pollution is mainly caused by particulates or soot pollution from wood smoke. Smoke from wood-burning fires is linked to illnesses such as asthma, bronchitis and lung disease, and is especially harmful for children and the elderly.
