Air Quality Alert issued June 7 at 3:39PM CDT by NWS St Louis MO

The St. Louis Clean Air Partnership has issued an air quality alert for the St. Louis metropolitan area from 10 AM to 8 PM CDT Thursday. An ORANGE (UNHEALTHY FOR SENSITIVE GROUPS) air quality forecast means that fine particulate concentrations are expected to reach levels that pose a health risk. Adverse health effects increase as air quality deteriorates. Ground-level fine particulates are 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.
