At Cape Fear Valley Medical Center, ER doctors treated several people Tuesday for heat exhaustion and heart attacks that may be heat related.
Doctors say it is best to limit outdoor physical activity when temperatures climb toward the triple digit mark, even if you think you are in good physical shape.
"It can be very serious and you can do long term damage neurologically," said Dr. David Messrly at Rex Hospital. "Your brain cannot function at temperature extremes and so if you get too hot, you can have problems and you can have long term damage."
Meanwhile, a Heat Advisory remains in effect for several counties as temperatures continue to stay high.
Wednesday's high is expected to be 97.
ABC11 Meteorologist Don "Big Weather" Schwenneker says a few showers and thunderstorms are possible Wednesday as the front will be in the vicinity.
"More scattered storms could refire on Thursday down in the Sandhills, but northern counties will stay dry," Schwenneker said. "One more hot day in the 90s on Wednesday before temperatures drop back down to near seasonal levels Thursday and Friday into the upper 80s."
