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.
