The highest AQ index in South Carolina (as of 17:00 EDT) is currently the Charleston area. Particle Pollution (PM2.5) is measuring at 63 (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 Greenville-Spartanburg 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.
The western half of SC is currently trending code yellow on this Wednesday while the eastern half is trending green. For Thursday, atmospheric moisture decreases some to encourage ozone formation, but that will be counteracted by a slightly stiffer west/southwesterly breeze that will help to disperse pollutants a little more. With these offsetting features, expect concentrations to be fairly similar to today. Thus, the Catawba and Charleston Tri-County regions will likely be CODE GREEN while all other regions could see CODE YELLOW.
