114º — that was the heat index for Columbia yesterday, and it's not going to feel much cooler today. The heat index is expected to hit 110° today, surpassing triple digits again.

The National Weather Service has also placed Columbia in a heat advisory today, meaning hot and humid temperatures could cause sicknesses like heat exhaustion or heat stroke. It's important to know the difference + recognize the signs.

Tips for staying cool

Air conditioning will be your best friend today, but it's also important to drink water and stay hydrated — even if you don't feel thirsty. Locals are encouraged to limit outdoor activities or go outside during the coolest parts of the day. If they do venture outdoors, they should wear light clothing.
