Almost All of Idaho Under Air Stagnation Advisory
Just about every county in Idaho is under an Air Stagnation Advisory through most of the weekend. Montana has a couple counties as well that qualify for a Stagnation Advisory.
An Air Stagnation Advisory is basically an alert to warn of stale, dirty air. Very little wind in occurring to bring in fresh air, especially in valleys.
Winter months can make this problematic because of heavy use of wood stoves and more particulates hanging in the air close to the ground.
Be extra careful if you have breathing problems of any kind. Poor quality air can be problematic for those at risk.
