The Arizona Department of Environmental Quality Ozone High Pollution Advisory for the Greater Phoenix Area will continue through the weekend. An air quality watch is in effect for Saturday, July 21, with the high pollution advisory reinstated for Sunday, July 22.

This means that forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates.

Ozone is an air contaminant which can cause breathing difficulties for children as well as persons with respiratory problems. A decrease in physical activity is recommended.

If it is a regularly scheduled work day, you are urged to car pool, telecommute or use mass transit.

The use of gasoline-powered equipment should be reduced or done late in the day. The Maricopa County ban on wood burning and commercial use of leaf blowing equipment is in effect.
