...AIR QUALITY ALERT IN EFFECT UNTIL 1 PM MDT SUNDAY...

The following message is transmitted on behalf of the Wyoming
Department of Environmental Quality, Air Quality Division, and the
Wyoming Department of Health.

* WHAT...Air Quality Alert for Wildfire Smoke.

* WHERE...Much of western Wyoming, generally along and west of a line
  from the Absaroka Mountains to the Wind River Basin and Green
  Mountains.

* WHEN...1 PM Friday, September 5, until 1 PM Sunday, September 7.

* IMPACTS...Smoke from distant wildfires burning in Idaho,
  Washington, and especially British Columbia, are responsible for a
  large amount of the recent smoke. In Wyoming, the Dollar Lake
  wildfire north-northwest of Pinedale will continue to push smoke
  into the Upper Green River Basin given the prevailing wind
  direction.

HEALTH INFORMATION...The Wyoming Department of Health recommends
that the elderly, young children, and individuals with respiratory
problems avoid excessive physical exertion and minimize outdoor
activities during this time. Wildfire smoke is made up of a variety
of pollutants, including particulate matter and ozone, which can
cause respiratory health effects. Although these people are most
susceptible to health impacts, the Department of Health also advises
that everyone should avoid prolonged exposure to poor air quality
conditions.

CURRENT CONDITIONS...The Wyoming Department of Environmental
Quality, Air Quality Division offers near real-time air quality data
for Wyoming`s monitoring stations and health effects information to
help the public interpret current conditions. Current air quality
conditions across the state of Wyoming can be found at
