PHOENIX, Ariz. – Dangerous heat and poor air quality continue to grip the Valley, with Maricopa County under dual warnings through Sunday night. Residents face a serious risk of heat-related illness and worsening ozone conditions, making travel and outdoor work hazardous.
According to the National Weather Service in Phoenix, an Extreme Heat Warning remains in effect until 8 p.m. Sunday, with afternoon highs between 107 and 112 degrees. The Arizona Department of Environmental Quality has also extended its Ozone High Pollution Advisory, cautioning against long periods outdoors, especially for children, older adults, and those with breathing issues.
Drivers on Interstate 10 and Loop 101 should prepare for possible vehicle overheating and tire blowouts during peak afternoon hours.

Cooling shelters across Maricopa County remain open, and residents can call 2-1-1 to find the nearest location. Officials recommend limiting outdoor activity, hydrating frequently, and wearing lightweight clothing. Gas-powered equipment use should be delayed until evening hours to reduce pollution.
