High temperatures and light winds, combined with vehicle exhaust, will result in smog, the Bay Area Air Quality Management District said in an alert sent Monday.
The alert will be effective Tuesday through Wednesday.
The National Weather Service is forecasting high temperatures for inland areas in the 90s to near 100, Tuesday through Friday.
Air alerts are issued when ozone pollution is forecast to reach unhealthy levels. Ozone can cause throat irritation, congestion and chest pain; it also can trigger asthma, inflame the lining of the lungs and worsen bronchitis and emphysema, according to the air district.
