Amateur video captures a weather phenomenon. » Watch video http://www.yahoo.com/s/332784 A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water and is connected to a cumuliform cloud. In the common form, it is a nonsupercell tornado over water [1]. Waterspouts, not associated with a rotating updraft of a supercell thunderstorm, are generally called "nontornadic waterspouts," or "fair-weather waterspouts,"[1] while those associated with mesocyclones are called "tornadic waterspouts". Tornadic waterspouts are generally more intense than nonsupercell waterspouts, and really just resemble a tornado on water. Fair weather waterspouts occur in coastal waters and are associated with usually weak, developing convective towers. They usually are F0, comprised of winds of less than 30 m/s. These are arguably the most common waterspouts in tropical climates, with upwards of 400 per year observed in the Florida Keys.[2] They generally develop in warm weather with light surface winds, and form from the bottom-up.[3] Fair-weather waterspouts are similar to landspouts. http://en.wikipedia.org/wiki/Waterspout Here is an interesting picture of a waterspout..
