Have any of you guys ever heard of a Tornado-Cane? I have seen one on Doppler Radar once here in FL near Tampa a couple of years ago, There was a tornado warning issued for that cell anyway.

A tornado-cane is a "Rare type of Super Cell Thunderstorm that takes the shape of a Hurricane Symbol with a small clear center"   I myself would not to experience one if there were to be one anywhere in U.S.A. it is a certainity that the National Weather Service would always issue a tornado warning.
