SAN FRANCISCO (KRON) — Several Southern California wildfires are impacting Bay Area air quality this weekend.
A Spare the Air alert is in effect through Sunday, according to the Bay Area Air Quality Management District.
KRON4’s Lydia Pantazes is reporting from San Francisco this morning.
She says this the first Spare the Air alert of the fall-winter season in the Bay Area.
Remember that wood fires are banned during these alerts.
Air quality is expected to be the worst in the North Bay, as conditions there are more stagnant.
There is a special warning Vallejo. Air quality there could be unhealthy for sensitive groups, like people suffering from asthma or respiratory illness.
Smoke traveling north from Southern California fires is not the only factor.
A high pressure ridge over California, reducing winds and trapping smoke and other particles near ground level, is a high-impact contributor to the problem.
Smoke from the #ThomasFire and other southern California fires will linger over the area today. This will bring lower air quality and visibility and colorful sunrise/sunsets as the smoke particles scatter out the blue/green wavelengths and leave behind the reds/oranges. pic.twitter.com/077jfHqamR
