36 Pit Fire - Smoke and Air Quality Report for 9/23/14

36 Pit Fire
Smoke and Air Quality Report for 9/23/14
Smoldering fuels, light winds and moist conditions will continue to generate smoke in the valleys and other areas within 5-10 miles of the 36 Pit Fire for the next few days.  Some smoke may drift further down the Clackamas River valley making it into the eastern Portland communities, mostly in the late night and morning hours.  Otherwise, air quality is expected to be good throughout the rest of the region through Thursday as an approaching weather system off the coast brings rain to northwestern Oregon.
