Phoenix, Arizona – Extreme heat will grip the Mazatzal Mountains, Superstition Mountains, and Southeast Gila County on Wednesday, as temperatures climb to 110°F by late afternoon and a heat advisory takes effect from 10 a.m. to 8 p.m.
According to the National Weather Service in Phoenix, a major heat risk is expected, especially for those working or spending time outdoors. Public safety officials warn that overexposure could quickly lead to heat cramps, heat exhaustion, or even life-threatening heat stroke if left unchecked.
Communities including Sunflower and nearby mountain towns should brace for dangerous midday conditions. The heat advisory covers popular hiking trails and major roads like State Route 87, where delays or closures could occur if emergencies arise. Local agencies recommend rescheduling strenuous activities for early morning or evening, and urge residents to check on vulnerable neighbors, seniors, and pets.
To stay safe, wear lightweight, loose-fitting clothes and drink extra water throughout the day. Employers are reminded to provide frequent breaks in the shade or air conditioning, per OSHA guidelines. Public cooling shelters are open in some counties; contact your local officials for locations and hours.
Heat advisories are likely to continue through the week, with updates possible as the pattern persists.
