The combination of temperatures warming into the lower to mid 90s with moderate levels of humidity will produce heat indices near 105 this afternoon across much of the South Carolina Lowcountry and Southeast Georgia. Those participating in outside September 11th memorial activities should be prepared for this level of heat and humidity today. Scattered showers and thunderstorms will produce relief in some areas later today. Cloud-to-ground lightning will pose a risk to anyone caught outdoors. Be prepared to seek shelter should thunderstorms approach. Remember, When Thunder Roars, Go Indoors!
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sunshine, and check up on relatives and neighbors. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. Lightning can strike 15 miles away from a thunderstorm. Seek safe shelter inside a building or vehicle should thunderstorms approach.
