Northern Rockies Complex Incident Management Team 3

#DerbyFire Ops Update Monday morning, Aug. 27, 2025. Philip Knaub, Operations Sections Chief, discusses firefighting tactics on the Derby Fire. The Derby Fire is now 4% contained. Firefighters were able to access the southeast fire perimeter yesterday and are confident that any changes in weather conditions will not push the fire over the control line in this area. Look for a black line on the fire map to illustrate containment. Rain reached most areas of the fire yesterday, however, dead and down trees continue to hold heat. Large fuels are slow to accept moisture and will continue to smolder. As the weather dries out later this week, we expect to see more active fire behavior. On the east and west sides of the fire perimeter, firefighters are scouting for opportunities to continue to build line with handcrews and heavy equipment.
