Ship workers were stunned when they saw this huge waterspout swirling in the waters around a Thai island.

The water funnel tornado was seen by locals and tourists near Koh Si Chang in Chonburi, eastern Thailand on the morning of April 30.

The huge waterspout, which was travelling at around 40mph, appeared two kilometres away from the island’s most popular shore, Tha Wang beach at 6.30 a.m. It was caused partly by soaring temperatures and humidity across the region.

Village chief Arkom Tanyongmas, who captured the natural phenomenon, said that it was the biggest tornado that had ever happened on the island.

He said: ''There has been this kind of tornado before but I have never seen it so huge and scary like this.

''It may be caused by the unpredictable weather. It’s very hot these days and it hasn’t rained on the island for a week.''

The tornado lasted for 30 minutes before it finally dispersed. Nobody was reportedly injured and no damages were caused.

''Luckily, the storm didn’t last long enough to hit the island. I couldn’t imagine what would happen if it did,'' Arkom ad
