It has a front

It has never had a ST 2.5/2.5

That is with out quastion a cold core system.


Ummm... the South Atlantic system has a front and it's fairly cold core and a majority of it's convection was amplified from cold-air stratocumulus. The water was only 67-69F. It had a ST2.5 rating for a short period of time.

This is a cold-core system with some minute subtropical characteristics.

I agree with you that this system had cold air moving into the system. With a lot of extratropical futures. Remember alot of storms(That area moving quickly northeastward)Over the north Atlatnic durning hurricane season also can have help from the upper levels. Which helps to form convection.

Also with this in the fact it is more extratropical can help it form over colder waters.

I agree but it cut off from the frontal system yesterday. At least that is the way it looks.

That was my point exactly....just because a storm system has a swirl to the clouds with an apparent "eye-like" spot in the center (like the Azores low) does not make it tropical in origin or structure. I remember someone posting a satellite photo recently of a storm system approaching the Oregon coast a few weeks ago that, to the naked eye, had the appearance of a hurricane, even with an eye-like structure with extensive convection around the center.

The point is, we must look at the broad picture when analyzing these systems....their means of origin, the environment in which they develop, sea surface temperatures...etc.... before we jump the gun and designate every swirl that happens to be located over an ocean as a tropical storm.

I'm not trying to bash Matt in any way, but I see a tendency for him to "jump-the-gun" a lot on over-rating various storm systems. He is certainly entitled to his opinion, but should refrain from the "@#*%(#$" comments he tosses out whenever anyone challenges a statement he makes. The forum should invite lively discussions and debates about the "blobs" we will see come-and-go through the upcoming season, but we must maintain a mature demeanor at all times to retain this board's credibility (which I think is OUTSTANDING!) and keep it fun for all....

just my two cents....

BTW...Matt....are you the "Head Forecater Matthew" from the Midwest Hurricane Center?

Alot of people try to put out other peoples options so all that is talked about is the so called expert or nhc. Important when it comes about the nhc or other offical places because they are the ones that keep us informed. But this is a messsage board. Why not allow people to have some fun/Discuse what they love? I'm not trying to bash no one. But I believe that it should be free to talk or discuse.

I knew that it was only subtropical at most. In I agree with that the seasurface temperature might be to cold(65 to 70 degrees). But when a system cuts off like that in moves north. In flare convection over the center. On less you forgot that is what Otto did last year. There is a big differences between a area of extratropical low pressure near the darn azores that is purely that. Then a low that is like the one in the south Atlatnic. Again I agree with many points put out by senorpepr, he is knowlegable. I could only hope to be only half as knowlegdeable then him. I agree alot with him. But this system doe's need to be noted thats all.

This is not jumping the gun remember I was not the one that posted this thread!!!

I guest that this is now gone. In lets just move on about it. Because its not worth fighting over.

Lets look for our next cyclone :P

At least I make my own forecast so there. At least I go with forecast models,Satellites in obs. I love hurricanes/weather. Its been my life for a very long time.
