The Big Grass Fire poses a significant threat to communities, homes, and infrastructure in Owyhee County, Idaho, and neighboring areas in Oregon. Over 350 residential structures are at risk, and the fire's rapid spread has necessitated the involvement of out-of-state fire crews. The fire's extreme behavior, fueled by dry conditions and lightning, has made containment efforts challenging. Evacuation orders are in place for some areas, including Silver City, which is under a Level 2 'Set' evacuation status (Idaho Capital Sun, 2026-07-29).
