We forecast the air quality in Oakridge and Westfir to reach Unhealthy for Sensitive Groups in the morning but we anticipate the afternoon conditions to improve to the Moderate range.
On Monday, northeast winds that should continue to push the majority of smoke to the South away from Oakridge and Westfir.
