The Arizona Department of Environmental Quality has extended an Ozone High Pollution Advisory for the Phoenix Metro Area through Thursday. Forecast weather conditions combined with existing ozone levels are expected to produce local maximum 8-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates.
Ozone can cause breathing difficulties for children, older adults, and persons with respiratory problems. The ADEQ recommends reducing physical activity, carpooling, telecommuting, or using mass transit. Gasoline-powered equipment use should be reduced or performed late in the day. For details, visit www.azdeq.gov/forecast/phoenix or call 602-771-2300. The alert is effective through Thursday at 9 p.m. MST.
