Air Quality Alert
Issued: 2:51 PM Apr. 24, 2026 – National Weather Service
...AIR QUALITY ALERT IN EFFECT UNTIL 8 PM THIS EVENING... The South Carolina Department of Environmental Services (SCDES) has issued a Code Orange Ground Level Ozone Action Day for the Upstate region region of South Carolina, until 8 PM EDT this evening. High pressure will continue to control the weather over the Southeast states today. High levels of pollutants will persist across the Upstate region of South Carolina. This, along with low humidity, very warm temperatures, and mostly sunny skies, will result in significant ground-level ozone production across the Upstate. 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.
