Carlisle, SC Warnings, Watches and Advisories

When a severe thunderstorm warning is issued, the storm may produce damaging winds, large hail, dangerous lightning, and heavy rain. In some cases, heavy rainfall produced by a severe storm can also lead to flash flooding. Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location. This is done to help with preparing for severe weather that may overlap or be heading towards Carlisle.

Air Quality Alert issued July 17 at 12:45AM EDT by NWS Greenville-Spartanburg SC

The South Carolina Department of Environmental Services (SCDES) has issued a Code Orange Ground Level Ozone Action Day for the Catawba region of South Carolina, from 10 AM this morning to 8 PM EDT this evening. Dominant high pressure will ensure minimal cloud cover and light and variable winds. Long-range wildfire smoke will also transport ozone precursors into the area. These factors will allow for sufficient ozone production, compounding with weak dispersion characteristics of an already pollutant-loaded atmosphere. 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.
