Phoenix, Arizona – Life in the Valley will come to a standstill as dangerous heat grips the Phoenix metro and surrounding counties, with afternoon highs reaching 114°F from 10 a.m. Friday through 8 p.m. Saturday.
According to the National Weather Service, an Extreme Heat Warning covers Maricopa County—including Phoenix, Mesa, Scottsdale, Glendale, and Paradise Valley—as well as Gila Bend, Tonopah Desert, and the Sonoran Desert National Monument. Temperatures across the region are expected to climb above 110°F, with some areas in the Northwest and East Valleys hitting 114°F.
The risk of heat-related illness will be extremely high, especially for anyone working or spending time outdoors. City officials urge residents to stay indoors during peak heat, seek out public cooling centers, and keep hydrated. Maricopa County residents can call 2-1-1 for free cooling shelter locations, transportation, and water. OSHA recommends scheduling frequent rest breaks in shaded or air-conditioned areas, and warns that heat stroke can strike quickly—call 911 immediately if symptoms appear.
Impacts will be widespread: major highways like I-10, I-17, and Loop 202 may see vehicle breakdowns or tire blowouts. Power demand could strain the grid, so Arizonans are advised to charge devices in advance and avoid unnecessary travel.
This event rivals last summer’s record-breaking July heat and is expected to linger through early Saturday night. More advisories may follow if triple-digit temperatures persist into Sunday.
Warnings remain in effect through 8 p.m. Saturday. Further updates will be issued as conditions develop.
