FLAGSTAFF — Motorists traveling on Interstate 17 and State Route 87 in northern Arizona are likely to see smoke over the next week from three fires burning in the Coconino National Forest.

The Cowboy, Mormon and Pivot Rock fires are relatively small in size, and the U.S. Forest Service is allowing them to burn. Smoke could be visible through the weekend from all three fires.

The Cowboy fire is just east of I-17 at the Kelly Canyon Road interchange north of Munds Park. There could be heavy smoke along I-17 between the Newman Park Road and Kelly Canyon Road interchanges on Tuesday as Forest Service crews manage the fire along the interstate.

Flames will be visible from I-17. Smoke will most likely settle over the interstate Tuesday night.

Motorists are advised to use caution, as the smoke could reduce visibility and firefighters will be working near the highway.

Smoke from the Mormon fire, about five miles east of Munds Park, could affect visibility along SR 87 north of Clints Well.

Smoke from the Pivot Rock fire near SR 87 at milepost 284 could also affect visibility along the highway south of Clints Well.

Motorists traveling along State Route 288 north of Roosevelt Lake may also encounter smoke from the Juniper fire, another managed fire in the Sierra Ancha Wilderness Area of the Tonto National Forest.

The Forest Service, under certain conditions, allows fires to burn to reduce fuels and the risk of more severe wildfires. During managed fire operations, community members and visitors may see fire personnel and vehicles in the vicinity.
