A “Spare the Air” alert has been issued by the Bay Area Air Quality Management District for Saturday, air quality officials said today.

High temperatures, low winds and exhaust fumes from vehicles are expected to create an unhealthy accumulation of ozone in the region, according to air quality officials.

On days when the alerts are issued, Bay Area residents and visitors are advised to walk, bike, carpool or use public transit instead of driving alone if possible.

There is no free transit available on Saturday and, unlike winter “Spare the Air” alerts, there is no ban on wood burning in place, air quality officials said.

The alert is the first in the Bay Area since June 7 and the fourth since the summer “Spare the Air” season started on May 1.
