SAN FRANCISCO, Calif. (KRON) — Throughout the Bay Area unhealthy levels of air quality is expected to continue this week due to the ongoing wildfires. 

The Bay Area Air Quality Management District announced Tuesday they are extending their Spare the Air alerts through Thursday.

 “We expect air quality to be in the unhealthy for sensitive groups category for isolated areas across the Bay Area, particularly in the North Bay and Peninsula,” said Charley Knoderer, Meteorologist with the Bay Area Air Quality Management District.

“We are extending our Spare the Air alerts through September  third this would be our sixteenth and seventeenth consecutive Spare the Air alerts.”

The Bay Area Air Quality Management District created the Spare the Air alerts to provide the public advanced notice when air quality is expected to be unhealthy and more.
