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 concentrations on this hot Tuesday afternoon are trending solidly in the yellow category for the Catawba zone, while other zones are trending anywhere from code green to low code yellow. A hot ridge of high pressure aloft dominates the weather pattern through tomorrow (and beyond). It is acting to suppress much of our cloud development and afternoon convection. Thus, we expect mainly dry, sunny, and hot conditions again for tomorrow, along with a light wind regime. Fortunately, clean sourcing and humid conditions will curtail ozone production somewhat. Expect the highest concentrations to occur across the Catawba, Midlands, CSRA, and Pee Dee regions, where Code YELLOW is being forecast. The Upstate and Trident zones will be cleaner and code GREEN.
