A waterspout is a whirling column of air and water mist. According to NOAA's National Weather Service, the best way to avoid a waterspout is to move at a 90-degree angle to its apparent movement. Never move closer to investigate a waterspout.Some can be just as dangerous as tornadoes.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.hile 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 so they normally move very little.
