The South ATLC peeps are looking in the wrong place

[AJC3]

Don't have a lot of time on my hands, however there appears to be a bona-fide midget tropical cyclone off the coast of Brazil.

Sat image to follow...




Looks more impressive in a time lapse. Will try and post something when I get a little more time.

[senorpepr]

I was just looking at this. Rather small, but it is listed on NRL's page under 90L.

Invest 90L
29.0S 42.5W ()

NAmb

[P.K.]

Phase diagrams say it is cold cored, although not nearly as deep as the low further off the coast.

[AJC3]

Interesting about the phase diagrams. Based on satellite appearance and central convection, I still think there is likely a small warm core embedded in there.

Here's a time lapse. Will go back in time and look at some IR images from last night when the system was near the coast.

A rather old Quikscat, but interesting nonetheless...

NNNN

[MiamiensisWx]

Catarina's cousin?

[Coredesat]

IR shows some (weak) convection near the center:

[senorpepr]

Personally, I think this should have been labelled 90T rather than 90L...

[P.K.]

Me too but I guess the NRL page won't do that? I've labelled it 90T on the UK forum I post on.

[James]

That's in pretty much the same place as the 2004 system as well, by the look of it.

[senorpepr]

I think the folks at NRL are reading S2K... lol

90Q is now listed...

[senorpepr]

I think the folks at NRL are reading S2K... lol

90Q is now listed...

[MiamiensisWx]

James, the 2004 system was called Catarina.

[P.K.]

Q?? Given the Met Office I believe it was gave this area the letter T I'll stick with that.

[MiamiensisWx]

Looks like there might be a small, weak warm core...

[senorpepr]

Q?? Given the Met Office I believe it was gave this area the letter T I'll stick with that.

Well, T only makes sense. A is taken, L is taken, T seems logical. Then again... we're talking about the US Navy here. (I didn't say that.)

[JonathanBelles]

90 Q, T, L? whats the difference?

[James]

James, the 2004 system was called Catarina.

Thanks

[HURAKAN]

LOOKS REALLY A SMALL SYSTEM.
