The MTBRF North Fork Fire grew approximately 10 acres to the south and east of its perimeter as of July 31, according to official records. Firefighters are actively working on fuel breaks north of Lost Horse Road and east of the fire area.
A temporary flight restriction (TFR) is in place over the fire operations area, prohibiting drones and non-fire aircraft. Critical fire weather, including a dry cold front and breakdown of an upper-level ridge, is expected this Saturday, which may increase fire behavior. No evacuation routes are available by foot or vehicle in high-risk areas due to steep, rocky terrain.
