The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix Metro Area on Tuesday, with the National Weather Service relaying the alert at 10:21 a.m. MST. The advisory runs through 9 p.m. Tuesday, August 25.
Forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk, according to the NWS alert. Adverse health effects increase as air quality deteriorates.

Residents are urged to carpool, telecommute, or use mass transit. The use of gasoline-powered equipment should be reduced or done late in the day.
