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 (UNHEALTHY FOR SENSITIVE GROUPS) 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. For more information
