The Arizona Department of Environmental Quality has issued an Ozone High Pollution Advisory for the Phoenix metro area, in effect through 9 p.m. tonight, according to a National Weather Service alert issued at 10:08 a.m. Monday.
Forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk, the alert states. Adverse health effects increase as air quality deteriorates.
Ozone is an air contaminant that can cause breathing difficulties for children, older adults, and persons with respiratory problems. A decrease in physical activity is recommended for those groups.
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, when ozone-forming conditions are less intense.
