Such heat is “rare, dangerous and deadly,” according to a National Weather Service warning. During heat waves, people should watch for signs of heat exhaustion and heat stroke, including high body temperature, dizziness and nausea. As in previous heat waves, those living in high heat zones are urged to limit outdoor activities this weekend and to seek shelter in air-conditioned buildings. “This is extreme even for our standards,” said Matthew Hirsch, a weather service meteorologist in Phoenix. Though accustomed to triple digits, the upcoming heat spell is a rarity in Phoenix, a desert metropolis of 1.5 million people, raising concerns of heat stroke.
