Waterspouts are intense columns of swirling tornado clouds that form over a body of water. They are most commonly found in subtropical areas and disappear shortly after they come into contact with land.

They are formed when pockets of warm air near the water surface rise suddenly. Cooler air is then sucked into the low-pressure air, which picks up water and rises towards the clouds in a rotating motion.
