CHARLOTTE, N.C. — Expect dangerous and life-threatening heat in Charlotte this weekend as the heat index climbs to near 105 degrees.

With temperatures in the mid 90s, and dewpoints in the lower 70s, the combined heat index will certainly cross into the triple digits, said First Warn Chief Meteorologist Brad Panovich. 

For the first time since 2016, the National Weather Service has issued a Heat Advisory for Charlotte.

A Heat Advisory means that hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible.

"Heat is the number one weather killer in the United States," said Panovich. "More than tornado, lightning, or hurricanes."

In 2018, the United States experienced 108 heat-related deaths.

"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.," the National Weather Service said in a released weather bulletin.

The Heat Advisory goes into effect for Mecklenburg, Iredell, Davie, Rowan, Gaston, Cabarrus, Union, York, Chester and other surrounding counties at Noon Saturday. It continues through 8 p.m.

Those headed to Uptown Charlotte for the House of Soccer and the International Champions Cup should drink plenty of water, Panovich advised.

The Mecklenburg County Health Department said you really cannot drink too much water in very high temperatures. The county urged anyone without shelter to visit a library during the hottest parts of the day if no other shelter can be found.

The elderly and the very young are most at-risk for heat exhaustion and heatstroke. If you have an exercise program, the health director said move your workout to either early morning or late evening.
