A heat advisory has been issued for the region.

The National Weather Service Mount Holly NJ issued the warning for noon to 7 p.m. Heat index values will be between 100 to 104 degrees, with temperatures in the low to mid 90s.

The combination of hot temperatures and high humidity can contribute to heat illnesses: heat exhaustion and heat stroke.

While heat exhaustion and heat stroke are not synonymous, untreated heat exhaustion can lead to heat stroke. Symptoms of heat exhaustion include: confusion, dark-colored urine (a sign of dehydration), dizziness, fainting, fatigue, headache, muscle cramps, nausea, pale and clammy skin, profuse sweating and a rapid heartbeat (more than 100 beats per minutes when resting).


Anyone with these symptoms should get to a cool area and drink fluids and rest. If symptoms worsen, they should visit their local emergency room for an evaluation.

Heat stroke is when the body can no longer sweat and its temperature reaches 103 degrees or more. Symptoms including the high body temperature are hot, red, dry or moist skin; a rapid and strong pulse; and possible unconsciousness. Anyone with these symptoms should be immediately taken to the emergency room. Left untreated, heat stroke can cause permanent disabilities or death.

The NWS suggests people drink plenty of fluids and stay in air conditioning and out of the sun. If possible, reschedule outside work, or do that work in the evening. Wear light-weight, loose-fitting clothing.

If overcome by heat, more to a cool and shaded spot.
