The Arizona Department of Environmental Quality has issued an Ozone High Pollution Advisory for the Phoenix Metro Area, running from Thursday, May 8 through Sunday, May 10 at 9 p.m., according to a National Weather Service alert issued at 9:20 a.m. MST. Forecast weather conditions combined with existing ozone levels are expected to produce local maximum 8-hour ozone concentrations that pose a health risk, the alert states. Ozone can cause breathing difficulties for children, older adults, and people with respiratory problems, and adverse health effects increase as air quality deteriorates.

Use of gasoline-powered equipment should be reduced or deferred to late in the day. The advisory covers Maricopa, AZ and the broader Phoenix Metro Area.
