Weather question!?

Question

Um ok if this sounds really stupid or unsmart im sorry hehe :0

but anyway im on Kswo.com and its called My skywarn radar online and there is a long line of storms coming our way and it has this arrow that is pink pointing downward and it says it stands for Intense lower level rotation. any clues on what that is????? thanx alot! :)

Answer 1

That pink arrow pointing down would indicate a rotation that could produce a tornado.  Intense lower level rotation would indicate rotation in the storm and this could lead to a possible tornado.  This would cause the National Weather Service to issue a tornado warning for that area.
