| Powerful Waterspout |
A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water, connected to a cumuliform cloud. In the common form, it is a non-supercell tornado over water. While it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones do occur. Waterspouts do not suck up water; the water seen in the main funnel cloud is actually water droplets formed by condensation. 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.

Incredible Volcano and Waterspout Hawaii

| Volcano and Waterspouts by Bruce Omori |
The eruption of Hawaii’s Kilauea volcano inspires the formation of a waterspout in this undated photo. Waterspouts can emerge the way traditional tornadoes do, but not always. Many are created when near-surface winds suddenly change direction under a cloud that is producing a growing updraft. Unlike a tornado, a waterspout vortex and funnel cloud are created from the ground, or water, up.
