A terminal sign believed to be from Nashville's John C. Tune Airport has been whipped across the city in a powerful tornado, landing nearly 50 kilometres away.
The tornadoes tore through Central Tennessee, killing at least 25 people and leaving an estimated 45,000 residents in the famed Music City without power.
A state of emergency is in effect and the state's emergency management plan has been activated.
Aerial footage of Nashville's airport has showed the frightening trail of the destruction.
The video shows cars piled up, hangars and airplanes destroyed, with officials estimating the damage to be in the millions.
The storms sent debris flying through Nashville, but it's what landed up in one person's backyard that has taken many by surprise.
Journalist Josh Breslow shared photos on Twitter this morning of a crumpled green terminal sign with an arrow in the backyard of a friend in Mt Juliet, a city half an hour's drive out of Nashville.
As people responded, and the extent of the damage at John C Tune Airport was revealed, some believed the sign was from further afield.
"My friend found THIS airport terminal sign in her yard after the overnight storms. She lives in Mt. Juliet... more than *10* MILES from @Fly_Nashville"
"Some tweeters say it COULD have come from John C. Tune Airport, which took a direct hit from a tornado. That would be nearly *30* MILES from Mt. Juliet. So even crazier!"
Other users have also been sharing images of strange debris that's landed in their backyards after the tornadoes.
