Phoenix, Arizona — Dangerous triple-digit heat is gripping the Desert Southwest this week, with mid to upper 110s expected to shatter daily records through Friday. The National Weather Service warns that central and southern Arizona will bear the brunt, as a widespread Major to Extreme HeatRisk stretches from Phoenix and Tucson west toward southern California and south into New Mexico.
Heat-related illness is a growing concern, particularly for those without access to reliable cooling or hydration. Major highways, including I-10, I-17, and I-8, may see more breakdowns and emergency calls as engines overheat and drivers contend with the intense sun. Outdoor workers, older adults, and young children face the greatest danger, and area hospitals are bracing for an uptick in heat exhaustion cases.
Officials advise avoiding outdoor activities during peak afternoon hours, checking on neighbors, and making sure pets have shade and water. Residents are urged to charge devices and prepare for possible power outages as energy demand strains the grid.
Some relief may arrive by Saturday as temperatures begin to drop, but higher humidity could keep overnight conditions uncomfortably warm.
Extreme heat warnings remain in effect through Friday night, and additional advisories could be issued heading into the weekend.
