A Winter Spare the Air alert has been issued for Sunday, prohibiting the burning of wood in fireplaces and all other devices because officials are forecasting unhealthy air quality throughout the Bay Area.

It will be the record eighth consecutive day the Bay Area Air Quality Management District has issued the alert.

The wood-burning ban will be in effect both indoors and outdoors, in the counties of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo and Santa Clara. The alert also is being issued for southern Sonoma County and southwestern Solano County, officials said.

Consecutive days of chilly, still winter weather has produced stagnant, unhealthy air in the Bay Area, prompting the high number of recent alerts, district officials said.

Smoke from wood-burning fires is linked to asthma and other illnesses, and is especially harmful for children and the elderly, authorities said.
