The National Weather Service issued an Extreme Heat Warning for the Phoenix metropolitan area effective August 28 at 1:56 PM MST through August 29 at 8 PM MST. Afternoon temperatures are forecast to reach 108 to 113 degrees, creating major to extreme heat risk across Northwest Valley, Buckeye/Avondale, Deer Valley, Central Phoenix, North Phoenix/Glendale, Scottsdale/Paradise Valley, East Valley, South Mountain/Ahwatukee, and Southeast Valley/Queen Creek.
Heat-related illnesses increase significantly during extreme heat events. Overexposure can cause heat cramps and heat exhaustion, which can progress to heat stroke without intervention.
