The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix Metro Area on Friday, warning that forecast weather conditions combined with existing ozone levels are expected to produce local maximum 8-hour ozone concentrations that pose a health risk. The advisory, relayed by the National Weather Service Phoenix at 9:19 a.m. MST, runs through 9 p.m. Saturday, May 15.
Ozone is an air contaminant that can cause breathing difficulties for children, older adults, and people with respiratory problems. ADEQ says adverse health effects increase as air quality deteriorates and recommends a decrease in physical activity.
Residents are urged to carpool, telecommute, or use mass transit. The use of gasoline-powered equipment should be reduced or deferred until late in the day.
