OAKLAND -- The Bay Area Air Quality Management District has issued a Spare the Air alert for Wednesday because of a forecast of unhealthy smog levels in the region.

High inland temperatures and light winds are expected to combine with motor vehicle exhaust to create unhealthy levels of smog, otherwise known as ozone, according to the air district. Smoke from fires near the California-Oregon border may also contribute to the bad air quality.
