The Arizona Department of Environmental Quality in Phoenix has
extended an Ozone High Pollution Advisory for the Greater Phoenix

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
