Coconino National Forest fire managers will conduct two sets of burns this week. Starting today, 13 acres of piles will be burned ten miles north, northwest of Flagstaff near Hart Prairie. The burn is scheduled for two days. With southwest winds predicted, smoke is expected to move to the northeast. Smoke may be visible from Flagstaff, I-17, I-40 and Highways 180 and 89. Then Tuesday through Thursday, fire crews are expected to conduct a prescribed burn around 11 miles southeast of Sedona, near Apache Maid Mountain on the east side of Interstate-17. Just over 19-hundred acres are expected to be treated over the three days. The project will be divided into two separate areas over two days, but could extend to the weekend. Smoke will be noticeable to motorists along I-17 near the Stoneman Lake Road Exit and should move northeast. Smoke is expected to impact the Stoneman Lake area.
