The extreme heat poses significant risks to public health, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Daytime temperatures could reach as high as 120°F (48.9°C) in some areas, increasing the risk of heat-related illnesses like heat exhaustion and heatstroke. Outdoor workers, athletes, and individuals without access to air conditioning are especially at risk. The Arizona Department of Health Services advises limiting outdoor activities to cooler morning and evening hours to mitigate these risks.
