Bay Area air quality officials have issued a region-wide Spare the
Air alert for Saturday.
Hot temperatures and light winds are expected to result in
unhealthy amounts of pollution in the air, according to the Bay Area Air Quality Management District.
"Though summer is nearly over, hot temperatures and traffic
congestion continue to impact Bay Area air quality," said Jack Broadbent, the air district's executive officer.
There is no free transit offered today and there is no
wood-burning ban in place.
Air quality is expected to improve by the beginning or the middle
of next week as temperatures drop and winds pick up.
