Before this week's snow arrived, a storm system brought strong winds and damage to Claiborne County. Wednesday, National Weather Service crews surveyed the damage to determine what caused the damage.
Security footage from Claiborne County High School shows the storm move through Sunday night. It appears to show a funnel cloud move behind the school, but meteorologists say it wasn't a tornado; it was a strong gust of circulating wind.
The gust picked up a trailer and tossed it around the parking lot, and caused some other minor damage around the school.
The survey team says video like that can help them assess damage and future risks.
"Anytime we get information like this it's going to help us later in research and for new events that may crop up, something that we may be able to pick up on radar and the chances for a tornado or a gust-nado in this case may be better or greater, then maybe we can put something like that in a warning and have people take action immediately," said Anthony Cavallucci.
The storm also caused damage to some homes and knocked down trees and power lines in New Tazewell.
