The South Carolina Department of Environmental Services (SCDES) has issued a Code Orange Ground Level Ozone Action Day for the Upstate region of South Carolina, in effect from 10 AM to 8 PM EDT Friday. High pressure will continue to control the weather over the Southeast states on Friday. 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.

Special Weather Statement issued April 24 at 1:22PM EDT by NWS Raleigh NC

Effective: Fri April 24, 2026, 1:22 PM
Expires: Sat April 25, 2026, 8:00 AM

Breezy winds between 15-20 mph are expected during the day on Saturday. In addition, relative humidity values are likely to decrease to 20 to 30 percent during the afternoon hours. While there will be an increasing chance of showers and thunderstorms during the afternoon, storms may initially arrive with a risk of lightning but with limited rainfall. The combination of all of these factors will result in an increased risk of wildfires and fire spread. Dry grasses, dead leaves, and other tree litter could easily ignite and spread fire quickly. Residents and visitors are urged to properly dispose of cigarette butts, matches, and any other flammable items in appropriate containers. Additionally, exercise caution if operating any equipment that could create sparks, and keep vehicles off of dry leaves and grass. A statewide burn ban issued by the North Carolina Forest Service is currently in place. Open burning of any kind is illegal.
