Overview
- The Spokane complex produced rapid, destructive runs Tuesday that destroyed hundreds of buildings, placed tens of thousands under evacuation orders and led to the arrest of a 37-year-old suspect.
- More than 2 million acres are burning across Oregon and Washington, with several blazes showing extreme fire behavior as a heat ridge fuels flames and slows firefighters’ progress.
- Plumes from Washington, Oregon and British Columbia have been transported long distances, prompting a Bay Area air-quality advisory, warnings for western Washington and high‑risk alerts in parts of Metro Vancouver while smoke reaches Colorado, Oklahoma and portions of the Upper Midwest.
- Health officials warn that wildfire smoke contains fine particulate matter (PM2.5) that raises the risk of respiratory and cardiovascular problems, and that aged smoke can become more harmful even when it loses a smoky smell; recommended precautions include N95 respirators when outdoors, HEPA filtration indoors and limiting strenuous activity.
- Fire agencies have sent mutual‑aid crews to the region and continue containment work, but forecasts say smoke will likely linger through midweek until onshore flow or frontal changes allow gradual improvement, creating ongoing strain on resources and public health.
