One hypothesis offered to explain this phenomenon is that strong winds traveling over water sometimes pick up creatures such as fish or frogs, and carry them for up to several miles. However, this primary aspect of the phenomenon has never been witnessed or scientifically tested.
Sometimes the animals survive the fall, In some incidents, however, the animals are frozen to death or even completely encased in ice. Some cases occur just after storms having strong winds, especially during tornadoes.
