WEATHER WONDER

Most mesocyclones do not generate tornadoes. When a tornado does form, a small region of stretching occurs where the updraft meets the downdraft. The area is no larger than 0.62 miles (1 kilometer) in diameter and scientists still do not know the reasons that the stretching zone forms.

This is a great example of a waterspout. You can see the characteristic narrow rope-like funnel. These boats have a good, and scary, view!
