Air Quality

The two fires being managed to achieve resource objectives near Tusayan, Ariz., remain active while the other managed fires on the Kaibab National Forest and the North Rim of Grand Canyon National Park have slowed substantially or petered out due to rain. Much of northern Arizona has received substantial precipitation over the last few days, putting a damper on the naturally-ignited fires that were being managed to improve forest health and reduce the likelihood of future high-severity fires.

The fires being managed for resource benefit on the Kaibab National Forest and the North Rim of Grand Canyon National Park are growing slowly but steadily as weather conditions vary on a daily basis. Yesterday, the fires received varying amounts of precipitation, from a heavy downpour on the Sitgreaves Complex to more light and scattered rainfall on the fires further north.

The fires being managed for resource benefit on the Kaibab National Forest and the North Rim of Grand Canyon National Park increased in activity yesterday due to drier conditions. Fire managers are hopeful that the drier weather pattern will allow the fires to continue growing and achieving resource objectives such as improving forest health and reducing the likelihood of future high-severity fires.

With the return of monsoonal precipitation to all fires, growth and activity have slowed. Crews continue to monitor the fires and do preparation work ahead of drier conditions forecasted to return mid-week. Smoke will be much lighter today and tonight. Fire managers continue to coordinate with neighboring forests, national parks, municipal fire departments, and the Arizona Department of Environmental Quality to monitor smoke impacts.

Growth continued yesterday on all fires being managed for resource benefits with multiple objectives. Today crews continue to do preparation work ahead of managed ignitions and ignitions may occur on some fires. Fire managers continue to coordinate with neighboring forests, national parks, municipal fire departments, and the Arizona Department of Environmental Quality to monitor smoke impacts.

Yesterday, monsoonal winds pushed smoke into the Flagstaff, Sedona, and Verde Valley areas from the Sitgreaves Complex on the Kaibab National Forest near Parks, Ariz. With variable winds in the forecast, smoke is likely to drift toward these areas again for the next several days. Fire managers continue to coordinate with neighboring forests, national parks, municipal fire departments, and the Arizona Department of Environmental Quality to monitor smoke impacts.

Today crews will continue active managed ignitions on all three fires across the forest. These ignitions are to strengthen existing road perimeters and keep fire progressing within the planning areas. Crews on all fires are reporting good consumption of fuels, protection of archeological sites, and wildlife habitat benefits. Additionally, these fires help make local communities more resilient by reducing the threat of future high intensity wildfires.
