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.
The Spare the Air alert is the sixth issued for smog this year, air district officials said, noting that smog can cause medical issues like throat irritation, congestion and chest pain, and is particularly harmful to young children, older adults and people with respiratory and heart conditions.
According to CBS News Bay Area Chief Meteorologist Paul Heggen, air quality likely to reach the "unhealthy for sensitive groups" category in most inland parts of the Bay Area.
There have been multiple air quality advisories issued over the last ten days due to smoke from the Smith River Complex fire near the California-Oregon border and other fires in Northern California.
