The National Weather Service issued an Extreme Heat Warning for the entire Phoenix metropolitan area effective at 12:35 PM and expiring at 8 PM MST on June 25. Afternoon temperatures are expected to reach 108 to 112 degrees, creating a major 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 while drinking plenty of water. Maricopa County residents can call 2-1-1 to find free cooling centers, transportation, water, and additional resources.
