When a tornado forms over a body of water, a waterspout occurs. High layers of cool air blow across the water as warm, moist air sweeps up from below. This results in a thin, dense columnar vortex that sucks up water into a giant mushroom-shaped spray. This particularly impressive waterspout was photographed by "Buggie" Vegas, owner of Bridge Side Cabins and Marina in Grand Isle, Louisiana, on June 19. According the United States' National Weather Service, the waterspout did little damage.
