Powerful Extratropical Low near the Azores

[cycloneye]

SAT IMAGERY



Looks good however too far north in latitud and look left and you can see the big cold front and storm that affected the NE that will merge with it in the next couple of days.

[Tampa Bay Hurricane]

It'll be interesting to see what becomes of this system

705 PM EST MON DEC 12 2005

IN THE NE ATLC... 995
MB LOW IS NEAR 35N32W WITH STORM FORCE WINDS. THIS LOW IS
EMBEDDED IN LARGE UPPER TROUGH WITH AXIS FROM THE LOW SW TO 19N41W.
STATIONARY FRONT IS WELL E OF THE LOW AND IS DISSIPATING FROM 23N20W
TO 31N22W... STILL ASSISTING SOME TSTMS N OF 27N NEAR AND W OF THE
CANARY ISLAND UNTIL THE FRONTAL BOUNDARY. THE LOW IS SEPARATING
FROM ITS FRONTS AND CONVECTION IS DEEPENING A LITTLE AROUND THE
CENTER... THOUGH IT REMAINS QUITE SHALLOW. THE SATELLITE
PRESENTATION IS ALSO BECOMING MORE SUBTROPICALISH WITH TIME AS THE
SYSTEM LOSES FRONTAL CHARACTERISTICS AND SOME SHALLOW CONVECTION
FORMSNEAR THE CENTER. HOWEVER COMPUTER MODELS ARE A LITTLE LESS
ENTHUSIASTIC ABOUT THIS LOW ACQUIRING SIGNIFICANT SUBTROPICAL/
TROPICAL CHARACTERISTICS WITH TIME THAN YESTERDAY... BUT IT IS
WORTH WATCHING UNTIL IT MERGES WITH AN APPROACHING TROUGH IN A FEW
DAYS. A SURFACE TROUGH EXTENDS FROM 30N27W TO 24N35W WITH THE UPPER
TROUGH

HURAKAN I edited the title to include the 7:05 discussion from forecaster Blake who always does interesting discussions.

[Matt-hurricanewatcher]

Looks at satellite shows a system that looks will on its way to subtropical storm. . We will see what the nhc chooses to do with it.

[Derek Ortt]

I'll go with the earlier discussion, written by Cangialosi (who is now at TAFB... much to my displeasure

[f5]

<NHC"when will it ever end?"

[Matt-hurricanewatcher]

Its not going to cause any one any problems. So it can form as it wises!

[Recurve]

My new favorite word:

"SUBTROPICALISH"


Do those transition to "Extratropicaloid," maybe?

[whereverwx]

It may be battling the shear soon.

if Zeta forms i want it to stay a >

[cycloneye]

This morning it looks less impressive than yesterday with less convection.NHC didn't made a mention of the low at the 7 AM EST discussion.

[HURAKAN]

Images continue to indicate little change with our low pressure system. Little convection is associated with this system making possibilities of subtropical development as low as they have even been. I would say that at least for this system, "ZETA" is cancelled!

[fuzzyblow]

Look like another little low is developping S.E. of the previous one...?
But nothing monstrous

[Tampa Bay Hurricane]

naked swirl only some thin clouds rotating about the center with
a small area of storms on the SE side...
Would-be Zeta looks dead

[Coredesat]

That front is like a giant arm reaching out to grab it.
