Tammy

[Air Force Met]

Thunder maybe they are debating if it is subtropical or tropical?

No, they seem to be agree that tropical in the TWO. I think they took look to come up with a forecast.

They call it tropical because there was a big stink last year about sub-tropical cyclones. To avoid the confusion for those who don't know any better (and really...it's only a big deal to mets...to the average joe the effects are the same)...they call them tropical. However, if you look at the data...it has a lot of hybrid characteristics.

1) Large wind field. Edited to add: Especially one that is well removed from the center. If you look at the buoy reports...the strongest winds are east of Jax and Georgia. Winds within 40 miles of the center are not that bad at all.
2) Area of low pressure moved 200+ miles in 7 hours...towards an area that did not have a deep convective burst...but rather a nice area of diffluence aloft on the east side of a low (like you would see in a baroclinic system).
3) It's on the east side of an upper low with about 20-30 knots zipping over the top of it...and it's still deepening...which means only one thing...baroclinic deepening of the low.
4) To expand on the above: The system is deepning without a lot of convection near the center...and all the heavy convection is well east. That means the process of deepening is occuring in some other way that is not tropical (if it was tropical/barotropic deepening we would see lots of convection right over the center).
5) If you look on radar...it has a tail
6) If you didn't know it was Tammy...and looked at Satallite not knowing what time of year it was...you would think it was some sort of extratropical low.

It certainly isn't purely tropical...if it was...the pressure center would not have jumped 200 miles into an area with no deep convection and it would not be deepening with 20-30 knots of shear over it.

But...the bottom line is the diff b/w a hybrid and a truly tropical storm is only important to the meteorological discussion...not to the effects. So...the only peopole who really care are 1) Mets...and 2) People who really want a tropical system and can't stand the idea that what they are getting is not a true tropical storm

JohnG, not trying to make light of the situation, but can you imagine how many of those Tshirts you would sell??? Dorky, perhaps, but wow, what a great idea!

[Weatherfreak000]

could Stan's blob help Tammy over the GOM if they'd had to combine?

[NastyCat4]

I am just ticked, as I woke up, and the thing is right over me--wish the NHC had not slept through this one, as it would have been nice to know a storm was right over my neighborhood, and not going somewhere else.

what is this huge blog coming out of the ucatan??

[cinlfla]

Here Christy there is already a topic started about the blob.

Christy please if you are going to post in this thread Tammy is the theme not any other system.

Yes it is Nastycat4 but the weather is not all that bad here its a little rainy and breezy. It could be a whole lot worse.

It really just kinda formed there. The lowest pressure moved about 250 miles in 7 hours to the NNW and closed off. Given that was due to baroclinic deepening (there was no deep convection near it when it made the move)...it was kinda unexpected.

It reminds me of Tropical Storm Arlene in 1993. IT was in the BOC and then all of the sudden had moved 200+ miles to the NNW overnight when the center reformed.

Oh, I know--been thru 4 'canes myself. It would have been nice to prepare--didn't even get the shutters up, but probably won't need them, as they don't expect more than 40 PMH winds, and we get worse T-storms.

Lordy!

Tammy and Vinny!

The sum of all my fears!

I've known a couple of redneck womens named Tammy and they cud be real bad if they wanted to!

And Vinny a commin up from the Southwest!

I knowed a Vinny and he wuz a hit man fer the mafia and wuz bad to the bone!

Florida, youre time has come.......again.

Let's not get wrapped around the axil here with "you're time has come." No need to be so sensational about this. As far as Tammy goes...people get much worse thudnerstorms with a stong cold front. These aren't major hurricanes...nor will they be.

Let's not be so dramatic.

I understand your concerns with Tammy forming off our coast. I have also been through lots of tropical storms and several hurricanes. I have to say it was a surprise to wake up and see that our little invest went straight to tropical storm status.

Not to bad here this morning. I did decide to keep my son home however. We live on a barrier island and the school bus has to go over a bridge, it is also quite a long drive. Guess Im just being the paranoid mommy.. My son thinks this is just great, getting to stay home and he is not sick..

I think we may have some localized flooding here too, she really looks to be quite the rain maker.

Yea...the highest wind I can find is from just NE of the center and that's sustained at 27kts.

Wow that's a long way away. I was just looking in and around the system. I guess that's one of the characteristics of a subtropical storm...a large windfield?

LOL..AFM its time to concede...

If it looks tropical and smells tropical it must be tropical...

Tammy is purely Tropical...
