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 Tuesday 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 Wednesday.
