Central OR & JDICC Wildfire Air Quality Summary
Report
Prepared by Andrea Holland, Air Resource Advisor
Air Quality Outlook
Yesterday’s wind flow took
smoke from the South Fork Complex fires right into John Day and surrounding
communities. That smoke also
dampened the fire activity in the Bald Sisters Fire. Burns suffered heavy smoke
concentrations beginning early this morning; that smoke will likely clear by
late this morning. A similar
weather pattern is forecast for today with continued active burning from the
South Fork Complex fires sending smoke into the John Day area late
morning. Smoke from these fires
may once again minimize fire activity in the Bald Sisters Fire today. If that does not happen, this fire
may take off due to very dry conditions and produce significant smoke. Today’s winds will likely take smoke
into Burns from the South Fork Complex fires. Tomorrow, Burns may see some relief from smoke by morning
as weak westerly winds keep smoke closer to the sources. With its proximity to the South Fork
Complex, John Day will likely see smoke settling into the area beginning late
in the morning through late afternoon.
