}} A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water. They are connected to a towering cumuliform cloud or a cumulonimbus cloud.<ref name=Glossary>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In the common form, it is a non-supercell tornado over water.<ref name=Glossary/>

While it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones do occur.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Most waterspouts do not suck up water; they are small and weak rotating columns of air over water.<ref name=Glossary/><ref>{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref>

While waterspouts form mostly in the tropics and subtropical areas,<ref name=Glossary/> other areas also report waterspouts, including Europe, New Zealand, the Great Lakes and Antarctica.<ref name="lake_michigan">{{#invoke:citation/CS1|citation |CitationClass=news }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Although rare, waterspouts have been observed in connection with lake-effect snow precipitation bands.

Waterspouts have a five-part life cycle: formation of a dark spot on the water surface, spiral pattern on the water surface, formation of a spray ring, development of the visible condensation funnel, and ultimately decay.
