36 Pit Fire - Air Quality Report and Outlook for 9/18/14

36 Pit Fire
Air Quality Report and Outlook for 9/18/14
A weakening low pressure trough will slowly move through the area today, keeping humidities high and winds mostly from the west wind.  Firefighters are continuing the aggressive attack today and smoke impacts are expected to be limited to the eastern and northeastern sections of Clackamas County.  Light winds overnight may result in localized smoke impacts down the Clackamas River Valley into Estacada Friday morning.  Winds on Friday should be light, with smoke impacts primarily noticed within 10-15 miles of the 36 Pit Fire.  Friday night, winds will swing from west through north and then become easterly, pushing smoke towards Molalla and into the Willamette Valley on Saturday as temperatures rise and the air and fuels dry out.  The smoke this weekend is NOT expected to be as noticeable as last weekend’s impacts.
