What this means
NWS issues a Heat Advisory when the Heat Index (temperature + humidity) is forecast to reach 100°F+ for 2+ hours, or an Excessive Heat Warning at 105°F+. In South Carolina these typically happen in July and August. Heat is the #1 weather-related killer in the U.S. — more than tornadoes, floods, or cold.
What you can do
- Drink water before you're thirsty. Avoid alcohol and caffeine on hot days.
- Never leave kids or pets in a parked car — interior temps hit 125°F+ within 10 minutes.
- Find a cooling center: dial 2-1-1 or visit https://www.mi211.org
- Check on elderly neighbors at least twice on hot days — heat stroke can develop within 30 minutes.
