Heat advisory issued for Horry and Georgetown counties

The National Weather Service in Wilmington, N.C. issued a heat advisory for Horry and Georgetown counties Sunday morning.

The advisory is in effect from 11 a.m. to 7 p.m., according to a weather briefing.

The cities in our area affected are:

Conway, Red Hill, Myrtle Beach, Socastee, North Myrtle Beach, Garden City, Little River, Andrews, Georgetown and Murrells Inlet.

Temperatures will be in the lower 90s, but heat index values could be up to 108 degrees, forecasters said. Heat indices will peak during the mid to late afternoon, and finally drop below 105 early Sunday evening.

Weather officials say high heat and humidity will increase the risk for heat exhaustion and even heat stroke if precautionary measures are not taken.

“A heat advisory means that a period of hot temperatures combined with high humidity will create a situation in which heat illnesses may occur,” officials said in the briefing. “To reduce the risk of heat illness during outdoor work and activities, the occupational safety and health administration recommends scheduling frequent breaks in shaded or air conditioned environments.”
