South Carolina Air Quality Alert - Unknown | Effective 06/04/2026 22:20
The South Carolina Department of Environmental Services (SCDES) has<br />
issued a Code Orange Ground Level Ozone Action Day for the Upstate<br />
region of South Carolina, from 10 AM this morning to 8 PM EDT this<br />
evening.
Dominant high pressure will make sure cloud cover will be minimal,<br />
atmospheric moisture will remain relatively low, and winds will be<br />
light. These factors will allow for sufficient ozone production,<br />
compounding with weak pollutant dispersion characteristics of an<br />
already pollutant-loaded atmosphere.
