Air Quality Alert issued September 8 at 1:42AM CDT by NWS St Louis MO

Air Quality Alert

The St. Louis Clean Air Partnership has issued an air quality alert for the St. Louis metropolitan area from 10 AM this morning to 8 PM CDT this evening. An Orange air quality forecast means that maximum ozone concentrations are expected to reach levels that pose a health risk. Adverse health effects increase as air quality deteriorates. Ground- level ozone is an air contaminant which can cause breathing difficulties for children, older adults, as well as persons with respiratory problems. Reducing outdoor physical activity is recommended. If it is a regularly scheduled work day you are urged to consider telecommuting, carpooling, or utilizing public transit. Avoid excessive idling and do not top off when refueling motor vehicles. The use of gasoline-powered lawn equipment should be reduced or postponed until late in the day.
