AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Ozone conditions on this beautiful Saturday afternoon are finishing in the moderate code yellow category across the Upstate and Catawba zones with cleaner code green conditions occurring everywhere else. Not a whole lot changes for Sunday. High pressure remains the main driver in our weather pattern, maintaining the dry and stable conditions. However, a boost in pressure gradient from a very, very distant hurricane Maria between her circulation and the high pressure will allow a bit more velocity to the NE wind flow, helping to reduce concentrations a little bit. We still expect (lower) code YELLOW conditions to persist across the Upstate and Catawba zones, with green conditions forecast elsewhere.
