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: Saturday's ozone concentrations are peaking out in the yellow category for all areas of South Carolina but right at the coast. Ample sunshine and low humidity appears to be doing its magic to produce moderate ozone levels once again. Expect changes for the better (in terms of air quality, not weather!!) for Sunday. Low pressure will be crossing the Mississippi Valley and moving east toward South Carolina. As such, clouds will be on the increase from west to east, low level moisture will be going up, and showers are likely to develop, especially across the western areas of the state, late in the day. As such, as we lose the sunshine and dry air, ozone production goes down, and the forecast is for code GREEN for all zones.
