Charleston County is forecast to experience potentially record-breaking heat indices, with some of the highest values across the Southeast.
While Coastal South Carolina is currently under an Extreme Heat Warning, an Extreme Heat Watch is expected for Saturday from 11:00 am to 8:00 pm, with heat index values potentially reaching 117°F.
This is more than just a hot summer day. These conditions can become life-threatening, particularly with prolonged exposure or strenuous outdoor activity.
During this period of extreme heat, please encourage personnel and the public to:
- Drink plenty of water and electrolyte-containing fluids.
- Limit time outdoors, particularly in direct sunlight.
- Reduce or reschedule strenuous outdoor activities when possible.
- Wear lightweight, loose-fitting, moisture-wicking clothing.
- Check on individuals who may be especially vulnerable to extreme heat.
If someone shows signs of a heat-related emergency, call 911 immediately, move them to a cooler location, and begin cooling measures while awaiting emergency responders.
