KNOXVILLE, Tenn. (WATE) — The Knoxville area has once again been impacted by smoke from Canadian wildfires, with the Air Quality Index in the Unhealthy For Sensitive Groups category Thursday.

Additionally, ground-level ozone will play a role in our air quality today as we see hot high temperatures in the low 90s area-wide. Sunny and hot conditions can increase ground-level ozone concentrations.

On Thursday, the AQI is expected to remain above 100. Indexes between 101 to 150 are considered “unhealthy for some,” meaning those with asthma, emphysema or COPD as well as young children and the elderly may experience breathing difficulties. It is not recommended to be outdoors for an extended time today.

Those potentially impacted should consider reducing activity levels or shortening the amount of time they are active outdoors.
