36 Pit Fire Air Quality Report - 9/17/14

36 Pit Fire
Air Quality Report and Outlook for 9/17/14
Low pressure off the N. California coast is generating a moist flow from the south over most of western Oregon.  The cloudy conditions and higher humidities are enabling firefighters to attack the fire aggressively today while decreasing overall smoke production. This pattern will continue through Thursday, then Friday will see a transition to a drier, offshore flow for the weekend.  While some smoke may move into the area from fires in southern Oregon and northern California, air quality in northeastern Oregon is expected to be reasonably good into Friday.
