Greenville, South Carolina – Triple-digit heat index values are returning to the Carolinas, with the hottest conditions expected across Upstate South Carolina and northeast Georgia as dangerous heat settles into the region through at least Tuesday.
According to the National Weather Service in Greenville-Spartanburg, afternoon heat index values will climb into the upper 90s to lower 100s on Monday, with the most intense heat focused across the Upstate, where locations including Greenville, Spartanburg, Anderson, Greenwood and surrounding communities could see heat index values between 100 and 105 degrees. Similar conditions are expected Tuesday as hot, humid air remains in place.
While actual air temperatures will climb into the 90s, high humidity will make it feel significantly hotter during the afternoon and early evening. The greatest risk for heat-related illness will be during the peak heating hours, especially for people working outdoors, those participating in summer recreation and anyone without access to air conditioning.
Northeast Georgia, including Anderson’s neighboring communities near the state line, along with portions of western North Carolina, will also experience oppressive humidity, although the highest heat index values are expected to remain concentrated across the South Carolina Upstate and northeast Georgia.
Residents are encouraged to drink plenty of water, take frequent breaks if working outside, wear lightweight clothing and seek air-conditioned spaces whenever possible. Check on elderly neighbors and family members, and never leave children or pets unattended inside a parked vehicle.
The hot and humid pattern is expected to continue into the middle of the week, and additional heat advisories could become necessary if heat index values trend even higher.
