The highest AQ index in South Carolina (as of 20:00 EDT) is currently the Florence and Darlington area. Particle Pollution (PM2.5) is measuring at 76 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Aiken-Augusta - SC and GA area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
All regions are currently trending code green on this Tuesday. For Wednesday, the frontal passage overnight helps to clear the skies and drop surface-based moisture levels, both of which help to stimulate ozone formation. However, a northwesterly flow out of the mountains will bring some dispersion of pollutants to SC, helping to counteract some of the formation. The deciding factor for this forecast will likely be how much smoke intrusion is brought to the area from the fires in the northwestern US. Smoke brings in precursors that allow for more ozone to form. Thus, the Catawba and Charleston Tri-County regions will likely be CODE GREEN while other areas could be CODE YELLOW.
