The Bay Area Air Quality Management District has extended an air quality advisory until Wednesday as fire sites continue to grow in Northern California and smoke moves into the region.
In a statement Tuesday, the district said parts of Napa, Solano and Sonoma would be affected. Residents of North Bay counties may experience air quality ranging from moderate to unhealthy for sensitive groups.
Officials reminded residents that wildfire smoke contains fine particulates and other harmful pollutants, with the elderly, children and people with respiratory illnesses being particularly vulnerable. If possible and temperatures permitting, officials say residents should stay indoors and run air conditioners on recirculated air until smoke levels subside.
Although an air quality advisory has been issued, the air district said no Spare the Air warning is in effect because pollutant levels are not expected to exceed the national 24-hour health standard.
The Sites Fire, which is burning in Colusa County, was first reported Monday afternoon grew to 10,000 hectares on Tuesday morning. The cause of the fire is under investigation.
