Air Quality Alert issued September 14 at 1:46AM CDT by NWS St Louis MO

Non-Weather Emergency Message. Not sent to IPAWS.

Effective: Sun September 14, 2025, 1:46 AM
Expires: Mon September 15, 2025, 2:00 AM

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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
