Two pile burns are set for the Coconino National Forest this week. Fire managers are planning a green waste burn at Bly Pit near Happy Jack and Willard Springs Pit south off Flagstaff just off Interstate-17. The burns will take place Monday and Tuesday. Pile burns are dependent upon weather conditions and typically conducted during times when rain or snow has fallen in the area so green waste piles can burn hot, quickly, and efficiently. The Bly Pit and Willard Pit burns will allow residents in the area to have a place to take new debris prior to spring cleanup. Smoke will generally be heaviest Monday due to the amount of green waste at the sites and is predicted to move toward the northeast. Cooler temperatures at night may impact the local area with smoke that settles in low-lying areas. The Willard Pit burn may produce smoke impacts in the immediate area along Interstate 17, as well as Munds Park, Kachina, and Mountainaire. Both pits will likely be closed during the burns.
