The “quad-state tornado” was unusually long-lasting and strong for the time of year, weather experts said. The twister, which ripped through Monette, Ark., and Mayfield, Ky., on Friday evening is likely to have carved out a 240-mile path, crossing into Missouri and Tennessee, as well. If the tornado remained on the ground without interruption, it will rank as the longest tornado track in U.S. history and the first to cross through four states.

Kentucky Governor Andy Beshear more than 50 are dead in his state.

“Daybreak is going to bring more tough news. It has been one of the toughest nights in Kentucky history. Some areas have been hit in ways that are hard to put into words.”

Meanwhile, a tornado is being blamed for the collapse of an Amazon facility in suburban St. Louis. One person was killed at a nursing home in Arkansas. But hardest hit appears to be the town of Mayfield, Kentucky.

Some of the worst destruction from the Kentucky tornado was centered in Mayfield, a town of nearly 10,000 people. At least 110 people were huddled inside a candle factory in the area when a tornado ripped through. https://t.co/1VRJZXLBWw pic.twitter.com/Mh3i3oEzZa
