Central OR & JDICC Wildfire Air Quality Summary

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.
