Air Quality Officials Issue A Spare The Air Alarm
People across the San Francisco Bay Area are being asked to limit driving and avoid strenuous outdoor exercise on Wednesday due to unhealthy, smoggy air.
The Bay Area Air Quality Management District has issued the third "Spare the Air" alert of the season.
Officials say forecast temperatures in the 90s will create ideal conditions for turning factory and car exhaust into ground-level ozone, or smog.
People sensitive to dirty air are especially advised to limit time outside, particularly in the afternoon hours when temperatures are the hottest.
The "Spare the Air" summer ozone season continues through Sept. 30.
Officials say another alert could be issued for Thursday because of an early forecast for triple-digit temperatures.
