The National Weather Service has confirmed an EF-1 tornado touched down about four miles west of Cosby Thursday night.
The path stretched about a half mile, and was 150-yards wide, along Henrytown Road.
"Fortunately it wasn't a large area that was effected, nothing too incredibly intense, but still, one tree falling in the wrong place can kill somebody so we want everybody to be careful about what they do and when warnings are issued that they already take shelter," said George Mathews, a meteorologist with the National Weather Service.
Mathews surveyed the damage in Sevier and Cocke counties Friday afternoon, trying to decipher if it was a tornado or strong winds that ripped through the area.
"If the damage is kind of spread across a kind of wide area, and it kind of diffuses, that's probably not a tornado," said Mathews. "But if it's a really narrow path, like you're driving through the woods and it's a narrow path of destruction and trees down and everything, and then you get back out of it again, a lot of times that is as well."
No one was hurt in the tornado, or any of the other damage that stretched across Sevier and Cocke Counties. However, a man was injured in the Great Smoky Mountains National Park when a tree fell on him. He suffered a broken ankle.
Yards along Henrytown Road were littered with debris. One home's roof was ripped off. The family said they will be without power for a few days, and will be staying with friends.
