Weather Alerts and Warnings for Flagstaff

Air Quality Alert

Air Quality Alert issued June 29 at 11:23AM MST by NWS Flagstaff AZ
Jun 29, 12:23 PM Jul 1, 1:00 AM
The Arizona Department of Environmental Quality (ADEQ) has issued an
Ozone High Pollution Advisory for Flagstaff on Monday and Tuesday due
to the influence of the Pocket Fire.

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.

For details on this High Pollution Advisory, visit the ADEQ internet
site at www.azdeq.gov/forecast/flagstaff or call 602-771-2300.
