Indiana Unknown Air Quality Alert | Effective 07/17/2026 18:33

The officials at the Indiana Department of Environmental Management have declared an Air Quality Action Day, in effect from Friday through Monday. Heavy smoke is lingering for the northern half of Indiana currently divided by a stationary front. The front will lift north later Friday providing a brief break in levels before a system late Saturday will bring another round of smoke. High pressure in place Sunday and Monday will recirculate the smoke over most of the state with the primary concern remaining the northern half of Indiana. This smoke, in addition to the other meteorological factors such as light winds and predicted flow from the north, will produce high PM2.5 readings. This will produce high PM2.5 readings into the Unhealthy for Sensitive Groups (USG) for West Central Indiana, which includes White County. Due to observed and forecasted high concentrations of PM2.5 readings in the area, recommendations are for the pubic to avoid or limit outdoor exposure to wildfire smoke, reduce or avoid exertion or heavy work outdoors and keep windows and doors closed as much as possible.
