High temperatures will range between 105 to 110 degrees for Las Vegas, Pahrump and Barstow, California, with highs of 110 to 115 for Overton, Lake Mead National Recreation Area, Bullhead City, Needles and Lake Havasu City. The Kingman area will be 105 to 110 while 115 to 120 is expected for Death Valley National Park.
“Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities,” the warning states. “Children, the elderly and people with chronic ailments are usually the first to suffer from the heat. … Friends, relatives or neighbors should check on people who may be at risk.”
Residents are urged to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
Take extra precautions if you work or spend time outside. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, so call 911.
