...OZONE HIGH POLLUTION ADVISORY FOR MARICOPA COUNTY INCLUDING THE
PHOENIX METRO AREA EXTENDED THROUGH SUNDAY...

The Arizona Department of Environmental Quality (ADEQ) has extended
an Ozone High Pollution Advisory for the Phoenix Metro Area through
SUNDAY.

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, older adults, as well as persons with respiratory
problems. A decrease in physical activity is recommended.

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.
