| Brief Description | Air Quality Alert | |
| Detailed Description | The South Carolina Department of Environmental Services (SCDES) has issued a Code Orange Ozone Action Day for the Catawba and Upstate regions of South Carolina in effect from 10 AM to 8 PM EDT Monday. A combination of primed ozone formation conditions, owing to a lack of both morning cloud cover and excess moisture being introduced into the environment with the addition of a lack of pollutant dispersion characteristics from low wind speeds and a very stable atmosphere are anticipated to bring action level ozone concentrations to the defined forecast regions. This has been further compounded by higher than projected ozone readings from over the weekend and an influence from interactions with the Canadian wildfire smoke that has poured across the Plains and Southeast. All other forecast regions are projected to peak in code Yellow for Monday's ozone concentrations. An ozone action day means that atmospheric conditions will likely produce unhealthy concentrations of ground level ozone air pollution. A Code Orange forecast indicates that ground level ozone concentrations are expected to be unhealthy for sensitive groups, which includes people with lung disease, older adults and children. Sensitive groups should reduce prolonged or heavy outdoor exertion, take more breaks, and do less intense activities, especially during afternoon and early evening hours. You can help prevent ozone pollution by walking or riding your bicycle, taking your lunch to work, reducing idling, conserving energy, and keeping your vehicle properly tuned.
