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.

Forecast Discussion: We may see the Upstate and Trident zones finish at CODE YELLOW, while all other zones should finish at CODE GREEN for ground-level ozone this Friday afternoon. We should see plenty of sunshine and hotter temperatures on Saturday, as the upper-level ridge continues building over the Southeast. There is still plenty of dry air aloft that should help to ramp up ozone concentrations in the afternoon hours. An upper-level disturbance may bring some mid- to high-level cloudiness into the CSRA and western portions of the Upstate. This feature may keep ozone levels for the CSRA zone at the higher end of CODE GREEN, but all of the other forecast zones should be at CODE YELLOW on Saturday.
