SAN FRANCISCO (KRON) — An Air Quality Advisory is in place in the Bay Area on Thursday.

The Bay Area Air Quality Management District said wildfire smoke will be “mostly aloft with intermittent periods of smoke mixing to the surface, particularly at higher elevation locations in the North and East Bay regions.”

However, air quality is not expected to get particularly unhealthy, so people will not need to go out of their way to reduce air pollution while the advisory is in place.

The air quality management district says if you smell smoke, you should stay indoors with windows and doors closed. You should also set your car vent system and air conditioning unit t re-circulate air rather than pulling in smoky outdoor air.

Health effects of smoke exposure include irritated eyes and airways, causing coughing, a scratchy throat and irritated sinuses. The elderly, children and people with respiratory conditions like asthma should take extra precaution during the advisory.

The advisory was later extended through Friday.
