There will be a pair of prescribed burns near Flagstaff this week. Coconino National Forest fire officials say about 650 acres will be burned Tuesday, ten miles southeast of Flagstaff, just southeast of Marshall Lake. It is a one-day burn and smoke is expected to move to the northeast. Smoke may be visible from Lake Mary Road, Elk Park Meadows and parts of Flagstaff. Fire crews will burn 600 acres nine miles southwest of Flagstaff, just to the southwest of Kachina Village on Thursday. This burn is also planned for one day. Smoke is expected to move to the northeast and may impact Interstate-17, State Route 89A, Forest Highlands, Fort Tuthill and the Flagstaff Airport. These burns are necessary to burn fuels to eliminate the possibility of a larger fire in the future, and to improve the safety of the communities around them.
