Thursday morning there were very few wildfires producing large quantities of smoke, however the Kincade Fire 63 miles north of San Francisco has the potential to become an air quality problem for residents in northern California especially on Friday.

There is a surprising amount of smoke in the Northwest, especially in Idaho, Oregon, and western Montana presumably created by extensive prescribed burning.

Forecasts predict that smoke from the Whiskey Fire 10 miles southwest of the Flagstaff Airport will move into the city Friday afternoon. (see maps)

Thursday and Thursday night the wind from the east and northeast moved smoke from the fire off to the southwest but that direction is predicted to change shortly after noon Friday to come from the south and southwest, pushing the smoke into the Flagstaff area. If the fire activity continues on Saturday the smoke is expected to continue to impact the city.

Near surface smoke forecast for 6 p.m. MDT September 14, 2019, assuming significant activity on the fires continues.

The Whiskey Fire started September 2 on the Coconino National Forest and is being managed rather than completely suppressed. Thursday firefighters began conducting firing operations along Forest Road 231 to ensure the wildfire stays in its containment area. Today, Friday, the plan is to moderate but continue the firing operations through the weekend, according to information released by the Forest Service.

The agency said smoke may affect Flagstaff, Munds Park, Mountainaire, Kachina Village, Forest Highlands, Doney Park, Mormon Lake Village, Highway 89A Corridor, Sedona, Village of Oak Creek, and portions of Interstate 40.

The fire has burned 3,500 acres.
