Definition and Characteristics
A waterspout is a column of rotating air and water vapor that extends from the base of a cumulus or cumulonimbus cloud to the water’s surface. Waterspouts are essentially tornadoes that occur over water, and they share many of the same characteristics.
Waterspouts can vary greatly in appearance, shape, and size. They can be as narrow as a few feet across or as wide as several hundred feet. They can also be as short as a few hundred feet or as tall as several thousand feet.
Waterspouts typically have a funnel-shaped cloud at their top and a rotating column of water at their base.
Types of Waterspouts
There are two main types of waterspouts: tornadic and fair-weather.
- Tornadic waterspoutsare associated with thunderstorms and are formed in the same way as tornadoes. They are typically more powerful than fair-weather waterspouts and can cause significant damage.
- Fair-weather waterspoutsare not associated with thunderstorms and are formed by the rising of warm, moist air over a body of water. They are typically less powerful than tornadic waterspouts and rarely cause damage.
Types of Waterspouts
Waterspouts come in various types, each with distinct formation and characteristics. Understanding these types is crucial for proper identification and risk assessment.
Fair-Weather Waterspouts

Formation and Lifecycle
The development of waterspouts requires a unique set of atmospheric conditions. They typically form when warm, moist air rises rapidly, creating an area of low pressure at the surface. This low-pressure zone draws in surrounding air, which then rises and cools, condensing into clouds.
If the updrafts are strong enough, they can cause the water droplets in the clouds to spin, forming a waterspout.
The lifecycle of a waterspout typically consists of three stages:
Initial Development
- The first stage is the formation of a dark, rotating cloud column that extends from the base of the cloud to the water’s surface.
- As the updrafts intensify, the cloud column narrows and begins to rotate faster.
- A funnel cloud forms as the cloud column stretches downward toward the water.
Mature Stage
- The funnel cloud makes contact with the water’s surface, and a waterspout is born.
- The waterspout typically reaches its maximum height and intensity during this stage.
- The winds within the waterspout can reach speeds of up to 100 miles per hour (160 kilometers per hour), and the waterspout can generate waves up to 10 feet (3 meters) high.
Dissipation
- As the updrafts weaken, the waterspout begins to lose its intensity.
- The funnel cloud retracts into the cloud column, and the waterspout eventually dissipates.
- The entire lifecycle of a waterspout can last anywhere from a few minutes to several hours.
Impacts and Hazards
Waterspouts, despite their mesmerizing appearance, pose significant hazards and can be extremely dangerous.
The primary threat posed by waterspouts is their strong winds. These winds can reach speeds of up to 120 miles per hour, which is sufficient to cause extensive damage to boats, structures, and property. Waterspouts can also produce large waves, which can capsize boats and cause flooding.
