WATCH: Terrifying video shows massive tornado sweeping through Kentucky

An eerie video posted to social media shows a massive tornado in the distance as it moves through part of Kentucky during the night. 

Eddie Knight of Sacramento, Kentucky posted the 35-second footage to Twitter. It looks like something out of a horror movie: the video flashes from pitch black and then back to the tornado when the dark sky is lit up by lightning.

"Video of what I believe to be the tornado that traveled ~200 miles," Knight wrote on Twitter. "Video from my dad’s front porch between Bremen and Sacramento, Kentucky. Terrifying."

Kentucky’s governor says a devastating tornado touched down for 227 miles — more than 200 in his state — and deaths were feared in 10 counties.

Gov. Andy Beshear said at a news conference Saturday that at least 70 people were feared dead in Kentucky, and the death toll could exceed 100.

"This will be, I believe, the deadliest tornado system to ever run through Kentucky," Beshear said.
