The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix Metro Area on Thursday, effective 8:49 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, with adverse effects increasing as air quality deteriorates.
Ozone can cause breathing difficulties for children, older adults, and people with respiratory problems. The advisory expires at 9 p.m. MST. Residents are urged to carpool, telecommute, or use mass transit; reduce or delay gasoline-powered equipment use until late in the day; and decrease physical activity.
