An extreme heat warning remains in force across Phoenix and surrounding parts of central and southern Arizona, with temperatures expected to reach about 107F (42C) in the city before the alert expires at 8pm MST on Thursday, September 10.
The National Weather Service warning covers Central Phoenix, North Phoenix and Glendale, Scottsdale and Paradise Valley, the East Valley, Deer Valley, the Northwest Valley, South Mountain and Ahwatukee, and the Buckeye and Avondale areas.
It also includes Fountain Hills and East Mesa, Queen Creek and the Southeast Valley, the Gila River Valley, Gila Bend, the Tonopah Desert, the Sonoran Desert National Monument, Kofa, Cave Creek and New River, as well as parts of southeast Yuma County.
Forecasters say temperatures are running several degrees above normal, with widespread moderate to major heat risk across the lower deserts. Overnight temperatures are also expected to remain high, limiting relief from the heat.
People in affected areas have been advised to avoid strenuous outdoor activity during the hottest part of the day, drink plenty of water and take regular breaks in shaded or air-conditioned surroundings. Anyone showing signs of heat exhaustion or heat stroke should be moved to a cool place and given urgent medical attention.
