Continuing hot weather has prompted the Bay Area Air Quality Management District to call another Spare the Air alert for Wednesday, air district officials announced this afternoon.
The hot weather combined with light winds are expected to lead to more smog from vehicle exhaust, so residents are encouraged to walk, bike, take public transit or carpool in an effort to reduce pollution.
The air district called the season's fifth Spare the Air alert for Tuesday and another for today.
The heat wave is forecasted to persist throughout the week, so more Spare the Air alerts could be coming.
Smog can lead to health hazards like throat irritation, congestion and chest pain. People suffering respiratory conditions like asthma, bronchitis or emphysema could have their conditions aggravated, according to the air district.
