SALMON, ID - The Idaho Department of Environmental Quality has issued an air quality advisory until Monday for Lemhi County.
Satellite imagery shows smoke from the Moose Fire extending to Yellowstone National Park.
The Moose River Fire grew by 3,491 acres in one day, to a total of 32,330 acres.
New fire activity is expected in the area.
Officials say smoke is showing two patterns.
First, smoke from the higher elevation and more active heat sources will rise and move east above the Salmon River towards Dillon.
Second, smoke from smoldering and lower elevation fires is pooling in the Salmon River and Lemhi Valleys, resulting in unhealthy air quality.
There is reported reduced visibility on US Highway 93 between North Fork to Carmen.
The fire is still 0% contained.
