Rare and ominous UFO-like ‘roll cloud’

An enormous, tube-like cloud has been seen over the skies of Tennessee and left local residents bewildered. Images surfaced of the cylindrical cloud on Facebook, with some residents saying the ominous looking mass resembled a UFO.Mother and son, Colby and Angie Hutton, saw the phenomenon when they were driving over a bridge in Adamsville. With no idea what it was, the pair turned to Facebook for help and the image has now amassed more than 400 likes. Meteorologists have since identified it as a ‘roll cloud’, a rare sub-group of arcus clouds that often form before a storm. These rare clouds, that look like an apocalyptic vision, were officially named as a new type of cloud in the World Meteorological Organisation’s Cloud Atlas just last year. After being spotted online by local television station WMCTV, meteorologists were able to ease concerns surrounding the otherworldly formation. According to the US National Weather Service (NWS), these rare clouds are ‘low, horizontal tube-shaped arcus cloud associated with a thunderstorm gust front.’
