Flagstaff Ranger District fire managers will begin a prescribed burn just south of Flagstaff on Monday. The burn will work through a 266-acre area of land south of Forest Road 714. Smoke may impact the Flagstaff metropolitan area during the daytime, but could settle as lower evening temperatures come in. If temperatures drop, smoke may be visible from Mountainaire, Kachina, and Munds Park. The prescribed burns are used to reduce the build-up of dangerous fuel loads and prevent the risk of a catastrophic fire.
