Air Quality Outlook
|
Yesterday, winds paired with over 7500
acres burned in the South Fork Complex fires (SFC) drove smoke into Burns resulting in unhealthy
conditions for most of the morning. Today the SFC is not expected to burn as many acres as seen in the last two days. This and a
northeast wind should provide Burns some relief from smoke. Smoke will linger around the areas
near the SFC and Bald Sisters fire and may settle into communities around
John Day, Unity and Paulina later today. Tomorrow’s shift in winds will see flows from the south to
southeast. Fire behavior is
expected to increase with this wind shift. Sunday could see smoke affecting communities north to
northwest of the fires. Areas
around John Day, Mitchell, and Paulina may see moderate smoke impacts. Communities along the Deschutes River
valley may see some light smoke from SFC.
