Wildfire smoke from multiple active fires in Oregon and neighboring states is degrading air quality across a large swath of the Pacific Northwest this week, with the most severe impacts concentrated in Jackson County and the Medford metropolitan area of southwestern Oregon. Health officials are urging sensitive populations to limit outdoor exposure as smoke plumes drift hundreds of miles from their source fires.

Evans Creek Fire Drives Medford Smoke Event

The East Evans Creek Road Fire burning near Rogue River in Jackson County is generating the most significant local smoke impact in the region. The fire's moderate-to-heavy density smoke plume has been observed by satellite drifting northeastward across central and eastern Washington and into northern Idaho. Residents in Medford, Ashland, Grants Pass, and surrounding communities are experiencing reduced visibility and elevated particulate levels.

Oregon DEQ Air Quality monitors in Jackson County have registered elevated PM2.5 concentrations. At these levels, the Air Quality Index falls into the Unhealthy for Sensitive Groups or Unhealthy range. People with asthma, heart disease, elderly individuals, and children are particularly vulnerable and should remain indoors with windows closed when possible.

Northeast Oregon and Whitman Area Fires

Wildfires burning near the Whitman National Forest in northeastern Oregon are producing individual light-density smoke plumes that are also drifting into parts of southern Washington and northern Idaho. While less intense than the Evans Creek smoke, this additional layer contributes to reduced air quality across a broader geographic footprint.

Spokane and Eastern Washington

The Spokane Regional Clean Air Agency has forecast AQI-Moderate conditions for the Spokane area on Sunday and Monday, driven by a combination of calm, hot weather reducing ventilation and the potential for smoke transport from Oregon and Idaho fires. Spokane-area residents are advised that wildfire smoke can cause air quality to deteriorate rapidly during fire season, and to be prepared to limit outdoor activity on short notice.

Protecting Yourself from Wildfire Smoke

  • Check current AQI at AirNow.gov or your state's air quality monitoring agency before outdoor activities.
  • Keep windows and doors closed during smoke events; use air conditioning set to recirculate indoor air.
  • Use portable air purifiers with HEPA filters indoors if available.
  • N95 or KN95 respirator masks (properly fitted) can reduce smoke inhalation if you must be outdoors. Cloth masks and surgical masks do not filter fine particles effectively.
  • Reduce strenuous outdoor activity when AQI exceeds 100 (Unhealthy for Sensitive Groups).
  • Keep pets indoors and provide extra water.

Resources

Residents can track current and forecast smoke conditions using AirNow.gov, the Washington Department of Ecology's Air Quality app, or Oregon DEQ's AQI monitoring website. The USFS Smoke Forecasting System also provides regional smoke dispersion forecasts updated daily during fire season.
