Wind-driven Old Trails Fire burns through parts of the Spokane area, forcing numerous evacuations
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Visible images with an overlay of the Fire Mask derived product (above) showed the Old Trails Fire (initially named the Euclid Fire) as it started around 1907 UTC on 01 August 2026 — then grew rapidly as strong SW winds (with gusts as high as 40 knots) quickly pushed the wildfire toward northwestern portions of the Spokane, Washington area (forcing numerous evacuations). SPC had highlighted much of eastern Washington as having an Extreme Fire Risk on that day — and a rare Particularly Dangerous Situation (PDS) Red Flag Warning was issued for the area.
