High temperatures in the mid-90s will combine with very high levels of humidity to produce heat index values of around 115° this afternoon in the Charleston metro and along the US 17 corridor.

During excessive heat, the National Weather Service advises folks to:

  • Find air conditioning.

  • Wear light clothing.
  • Check on family members and neighbors.
  • Drink plenty of water.
  • Watch for heat cramps, exhaustion, stroke.

Hazardous heat conditions are forecasted to continue through the week.
