Trigg and Christian counties and 16 middle Tennessee counties are under an Air Quality Alert Wednesday.
The Tennessee Department of Environment and Conservation issued the Code Orange Health Advisory for the Nashville and Clarksville areas, which remains in effect until 11:59 Wednesday night.
The alert means ground-level particulate matter concentrations within the region may approach or exceed unhealthy standards. The department added the general public is not likely to be affected, but active children and adults, and people with respiratory diseases such as Asthma, should limit prolonged outdoor activities.
The issue comes as wildfire smoke from the western United States is making its way to the region.
