EXTREME HEAT WARNING: The National Weather Service in Phoenix has issued an Extreme Heat Warning for Scottsdale, Paradise Valley, and the broader Phoenix metropolitan area, effective through 8 p.m. MST Monday, July 27.
Afternoon temperatures across South Central Arizona are forecast to reach 106 to 118 degrees, with overnight lows remaining in the upper 80s to mid-90s. The NWS has classified the event as a Major Heat Risk. The warning covers Northwest Valley, Buckeye/Avondale, Deer Valley, Central Phoenix, North Phoenix/Glendale, Scottsdale/Paradise Valley, East Valley, South Mountain/Ahwatukee, and the Southeast Valley/Queen Creek corridor.
The NWS warns that heat-related illnesses increase significantly during events of this magnitude. Overexposure can progress from heat cramps and heat exhaustion to heat stroke without intervention. Anyone overcome by heat should be moved immediately to a cool, shaded location; heat stroke requires a call to 911.
For outdoor workers, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments and rescheduling strenuous activity to early morning or evening hours when possible. Lightweight, loose-fitting clothing and consistent water intake are advised for anyone spending time outside.
Maricopa County residents can call 2-1-1 to find a free cooling center, transportation assistance, water, and additional resources. Public cooling shelters are available in some areas; county officials can provide location details.
