this is a relative new phenomenon here in Thailand. A waterspout happens when water is pulled up to the sky and spirals like a little tornado. this can even happen on a fine sunny day. experts say a waterspout can happen both on land and at sea but they assure us that the kind of waterspout found in Thailand is not too dangerous as its force is only about 1 per cent that of a tornado and it only lasts few minutes. The waterspouts witnessed at sea; however, have been much more powerful, some with the strength to sink small boats.
