...AIR QUALITY ALERT IN EFFECT UNTIL 8 PM CDT THIS EVENING...
...AIR QUALITY ALERT IN EFFECT FROM 10 AM TO 8 PM CDT SATURDAY...

The St. Louis Clean Air Partnership has issued an air quality alert
for the St. Louis metropolitan area until 8 PM CDT this evening.

An Orange air quality forecast means that maximum ozone and fine
particulates concentrations are expected to reach levels that pose a
health risk. Adverse health effects increase as air quality
deteriorates. Ground-level ozone and fine particulates 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.
