Health advisory and Spare the Air alerts in effect for Bay Area

Overnight winds brought smoke into the Sacramento area from a complex of fires burning in Napa and Solano counties, leading to a noticeable drop in air quality early Wednesday.

Sean Raffuse, an air-quality analyst at the Crocker Nuclear Laboratory at University of California in Davis, told the Reno Gazette-Journal that early estimates project the fires have already produced about 10,000 tons of PM2.5.

These tiny particles are about 3 percent of the diameter of a human hair, which makes them even more risky because they can be inhaled into the lungs and bypass the body's filtration systems, slipping directly into the bloodstream. The current situation is a result of very unhealthy air quality from the wildfires in the North Bay and is causing unprecedented levels of air pollution throughout the Bay Area. "They exacerbate respiratory conditions like asthma, COPD (Chronic Obstructive Pulmonary Disease), emphysema and other conditions, because they are very harmful". The festival was expected to include a one mile race and a half marathon through the city streets, but concerns about "the health and safety of our athletes and volunteers" as well as a desire not to use "valuable Bay Area first responders and resources that can be better utilized elsewhere" caused its cancellation. The smoke kept many people indoors and those where outside call it unusual. You can look up your zip code here, and find a 5-day forecast here.

The smell of fire hangs in the air in San Francisco.

"We're going to see that north wind pick up again tonight and into Thursday and that means drier, warmer air", Flannigan said Wednesday. Fasano suggests staying inside as much as possible while skies are smoky to avoid breathing both particle pollution and ash wafting through the air.

Do not run fans drawing smoky air inside.

"Air quality has improved throughout the Bay Area, which is wonderful". Still, people without respiratory problems also were impacted by the shift in air quality.
