Best Answer

Officially, it is a tornado warning, which means that a tornado has been detected or that the formation of a tornado may be imminent.

Unofficially, it is a subcategory of tornado warning called a tornado emergency. A tornado emergency is issued when a large and intense tornado is threatening a populated area.
