The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix Metro Area on Thursday, May 7, effective from 9:30 a.m. to 9 p.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. ADEQ recommends reducing physical activity and urges residents to carpool, telecommute, or use mass transit. Gasoline-powered equipment use should be reduced or delayed until late in the day.
