The Hatcher Mountain/Indigo Lane fire, which has been fueled by high winds, has grown to approximately 1,000 acres, according to Perrin Anderson, the Assistant County Mayor in Sevier County.
At least 35 structures have been affected, he said.
The blaze location is about 30 miles southeast of Knoxville.
At least one person was injured and airlifted to an area hospital. The condition of that person is unknown.
The wind fueling the fire is part of the system wreaking havoc across the Southeast and Texas this week.
