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.
