BOULDER CITY, Nev. – The National Weather Service has issued an excessive heat warning for Lake Mead National Recreation Area until 8 p.m. July 1. Temperatures in the park are forecasted to be near or above 114 degrees Friday afternoon on Lake Mead with temperatures on Lake Mohave reaching into the 120s, and they are expected to remain in the triple digits over the next ten days.


According to the National Oceanic and Atmospheric Administration, heat is the number one weather-related killer in United States.


“These extreme temps could lead to heat-related injuries if precautions are not taken. We discourage people from hiking or participating in other strenuous outdoor activities at Lake Mead National Recreation Area while the warning is in place,” said park ranger Brandon Marsmaker.


People exposed to extreme heat may be at risk of heat stress, heat exhaustion or heat stroke. Some symptoms include hot, dry skin or profuse sweating, chills, throbbing headaches, dizziness, extreme weakness or muscle cramps.


“If you, or someone you’re with, begins to feel tired and flushed and begins to sweat excessively, you may be suffering from heat stress,” said Marsmaker. “Stop any strenuous activities immediately, drink water and find a cool place to rest.”


If someone starts to exhibit signs of nausea, vomiting, dizziness and/or weakness, they may be experiencing heat exhaustion and should seek medical attention.


If someone becomes disoriented, stops sweating, has hot dry skin, or even worse, passes out, that person is probably experiencing heat stroke, which is a serious medical condition.


“If someone experiences these symptoms, call 911 immediately,” said Marsmaker.


People exposed to extreme heat should avoid alcoholic and caffeinated beverages because they increase stress on the body and accelerate dehydration.


“If you’re coming out to enjoy Lake Mead or Lake Mohave this week, use a buddy system, monitor the condition of your friends and have someone do the same for you,” said Marsmaker. “Bring plenty of water, and don’t forget to provide water and shade for your pets.  And remember—children, the elderly and those with chronic ailments are the most susceptible to heat-related illness.”
