A Spare the Air alert has been issued for today in the Bay Area, the fourth such alert issued this month for unhealthy air conditions.
The Bay Area Air Quality Management District issued the alert because of forecasted high temperatures and light winds that are expected to
combine with motor vehicle exhaust to create unhealthy ozone accumulation in the region.
"Another heat wave serves as a reminder that we need to commute smarter every day to reduce smog and traffic gridlock," air district executive officer Jack Broadbent said.
Smog can cause throat irritation, congestion, chest pain and can trigger asthma or worsen bronchitis and emphysema.
