The Arizona Department of Forestry and Fire Management is planning two prescribed burns next week near Flagstaff. On Monday, 200 acres will be treated on the Walnut Project, which is eight miles east of Flagstaff and one mile south of Interstate-40, near Walnut Canyon. This burn is a continuation of a 450-acre burn project that started in October. Smoke could affect I-40 and nearby communities. The second burn will take place Tuesday north of Interstate-40, 11 miles northeast of Flagstaff and about four miles south of Doney Park. Fire crews will burn 150 acres called the Turkey Hill Prescribed Fire. Both projects consist of Ponderosa pine and fine fuel components. Winds could push smoke off to the northeast, away from Doney Park and I-40.
