Air Stagnation Advisory Added Until Next Tuesday for Tri-Cities
You may have noticed the air quality getting worse since Thursday, and you would be right.
The National Weather Service has issued an "Air Stagnation Advisory" until at least next Tuesday for the Tri-Cities and Columbia Basin area.
The bad air is being trapped by warm air high in the atmosphere that is holding this smoggy air down. There is also a very little amount of wind which compounds the problem.
