The National Weather Service issued an Extreme Heat Warning for the Phoenix metropolitan area effective August 23 through August 29 at 8 p.m. MST. Afternoon temperatures are expected to reach 108 to 116 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 without intervention can lead to heat stroke. Residents should take extra precautions if working or spending time outside, reschedule strenuous activities to early morning or evening when possible, and wear lightweight clothing. In Maricopa County, call 2-1-1 to find free cooling centers, transportation, water, and additional resources.
