The storm to my east has some rotation and is very strong!

by **Adam2014** 2012-03-31, 4:27 pm

There is some crazy good rotation on this storm.

TODAY (MARCH 31) SEVERE WEATHER.... Szj2nk

This storm is starting to develop a hook echo, it is very dangerous.

by **Adam2014** 2012-03-31, 4:55 pm

They need a tornado warning out now! This storm has rotation with a severe rating of an 8. Incredible!

by **Math/Met** 2012-03-31, 4:56 pm

That is a very impressive storm.

No way my parents would let me do that, plus there is baseball to softball sized hail reported with the storm. No way I am getting her dented lol. Severe rating down to 6 not has bad but still very concerning.

On Grl3 I imagine you know what that means, if not I will tell you now. It is probably the best radar software you can buy on line and I highly recommend it. Those are pictures that I posted of it, if you see in the picture you have a yellow rotation signature on the storm, that indicates about a 4 or 5 on the severe rating scale. The severe rating scale rates the storm from 1-25 one being weak and 25 being the end of the world.(lol)

The storm I was following that was just east of me yesterday went from a yellow signature to a red signature to a purple signature which means that it had a severe rating of 9 which is very dangerous!

by Vanster67 2012-04-01, 8:27 am

Adam, some really big hail down there close to you wasn't there?

by **Adam2014** 2012-04-01, 8:29 am
