Bathers rushed with their cellphones to get a snapshot of an impressive waterspout formed on Tuesday off the Greek island of Serifos in the Aegean.
The rare phenomenon was recorded on an amateur video from Megalo Livadi beach by Tzina Prokopiou as a weather front is sweeping through Greece, bringing heavy rains and a substantial drop in temperatures.
According to the U.S. National Ocean Service, waterspouts fall into two categories: fair weather waterspouts; and tornadic waterspouts.
Tornadic waterspouts are tornadoes that form over water, or move from land to water. They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning.
Fair weather waterspouts usually form along the dark flat base of a line of developing cumulus clouds. This type of waterspout is generally not associated with thunderstorms.
While tornadic waterspouts develop downward in a thunderstorm, a fair weather waterspout develops on the surface of the water and works its way upward.
By the time the funnel is visible, a fair weather waterspout is near maturity. Fair weather waterspouts form in light wind conditions, therefore normally move very little.
