The National Weather Service has upgraded a previously issued Excessive Heat Watch to an Extreme Heat Warning for the region from 11 a.m. to 7 p.m. today, with heat index values expected to peak between 112 and 116 degrees. Today marks the start of a Major Heat Risk period for the region.
City officials are urging residents to take precautions, both on the job and at home.
"This heat is dangerous, and it doesn't just affect people working outside," said Kaylan Koszela, Director of Resilience at the City of Charleston. "We want every household in Charleston to pay attention this week; check on your older neighbors, your kids, your pets, and don't wait until someone's in trouble to act."
Outdoor workers and crews are advised to monitor conditions closely, stay hydrated and adjust work schedules as needed.
Don't Wait, Hydrate
- Drink 8 ounces (one cup) of water every 15–20 minutes when working in the heat.
- Small, frequent amounts of water are more effective than drinking a lot infrequently.
- Waiting until you're thirsty means you're already behind on hydration.
Water. Rest. Shade.
- Make sure crews have water on hand.
- Take breaks before signs of heat-related illness appear, not after.
- Cool off in shade or air conditioning whenever possible.
Residents are encouraged to check on vulnerable family, friends, and neighbors during this heat event, and to never leave children, older adults, or pets in parked vehicles.
