The National Weather Service has issued another heat advisory as the week-long heat wave shows no signs of letting up.
Friday's heat advisory goes into effect from 11 a.m. to 6 p.m. for Berkeley, Charleston, Colleton, and Dorchester counties.
Temperatures will rise into the upper 90s, but officials warn high humidity levels will push the heat index to anywhere from 105 to 112 degrees.
While the temperatures will only just begin to crack 90 degrees by 11 a.m., the heat index will already be in the low 100s.
Dozens of counties in southeast South Carolina and Georgia will also feel the heat Friday.
To reduce the risk of heat exhaustion and heat stroke, be sure to drink plenty of fluids, wear light weight clothing, and stay out of direct sunlight.
