Footage shows a rare double-waterspout stretching from the sea to the clouds above in southern Thailand. The two elephant trunk-shaped streams of water appeared to be moving in sync alongside the island of Koh Mak in Trat province, on April 16. Onlooker Pakorn Sae Tiew said: "Clouds covered the sun and everywhere became darker. The tornados started very quickly with a spinning cloud of water spray next to the sea. Then they grew bigger." Single waterspouts are seen fairly regularly but two or more appearing at the same time is particularly rare. Those seen in the video are known as a fair weather waterspout. They are most commonly found in subtropical areas and usually disappear shortly after they come into contact with land.
