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.

Andmeallikad ja metoodika
Meie ilmaprognoosid põhinevad professionaalsel ilmaandmete pakkujal, mis koondab andmeid riiklikelt ilmateenistustelt, satelliidivaatlustelt, radarivõrkudelt ja enam kui 80 000 ilmajaamalt üle maailma. Prognoosiandmeid uuendatakse mitu korda päevas. Me teisendame toorandmed selgeteks kokkuvõteteks – tuulekiirus m/s-des, rõhk mmHg-des – et saaksite oma päeva enesekindlalt planeerida.
