36 Pit Fire
Air Quality Report for 9/22/14
|
Smoke from the 36 Pit Fire drifted
southeast yesterday (Sunday) afternoon and evening and resulted in elevated
PM2.5 values at the air quality monitor in Madras, although health warning
levels did not exceed Moderate at that location. Today transport winds will push smoke to
the northeast to east. As fire
activity moderates, smoke will not loft as high as the last two days so we expect
primarily localized air quality impacts in areas near the fire, especially in
the Clackamas river valley and possibly as far as the Deschutes river valley. The fire may receive a little rain on
Tuesday with a higher likelihood of rain on Wednesday which will greatly help
firefighting efforts. We don’t expect
serious air quality impacts but will remain vigilant.
