Lighter winds in the valley bring less smoke, moderate air quality

A smoke health advisory for the Bay Area was issued for the second day in a row Tuesday as multiple North Bay wildfires continue to billow tons of soot into the air.

The rest of the region, from Sacramento down to Modesto, was expected to be moderate to unhealthy for sensitive groups.

Continuing wind and wildfires today may cause residents to experience trouble breathing, coughing, headaches and chest pain.

Air pollution in counties of the San Francisco Bay Area this week has been the worst since 1999 when officials began collecting data.

"The North Bay fires have devastated families, homes, businesses, and schools across the region, and as first responders work tirelessly to put out the fires and aid those in need, Bay Area sports teams are unified in supporting relief efforts", said 49ers CEO Jed York via the statement sent out to the media.

The health center is handing out free dust masks for students that will protect against the smell but not against the particles in the air.

Jim Roberts, a research chemist from the National Oceanic and Atmospheric Administration's Earth System's Research Laboratory, told NBC that Rafusse's calculations "sounds about right". Residents should avoid outdoor activities, close windows and doors, and avoid using air-conditioning units, according to the warning.

Schools are keeping students indoors, even during recesses, and sports teams were canceling practices and games. "Our campus resources stand ready to help anyone in our community who is struggling with the impacts of these terrible fires".

According to the Enviromental Protection Agency, both short- and long-term exposures to high levels of PM2.5 concentrations have been shown to lead to harmful health effects, including links to death. "It's not good for air quality". Scarves or bandanas won't help either. It's important that you wear the respirator correctly, however.
