Seems like time for an advisory has passed. Maybe another WONT41 in half an hour.

[HURAKAN]

[tropicana]

or maybe another special advisory won't come til tomorrow morning, since there would be no real need to issue another special advisory tonight if not much has changed. Cant believe i stayed up late for this! haha well i woulda been up anyways.

Looks like a subtropical system.

Lingering Nina heat.

[MGC]

Looks like a pretty good system to me....Based on previous upgrades this should be at least a STS. Of course the NHC is the final judge. If it continues to organize I think the NHC will have no other choise than to upgrade.....MGC

[HURAKAN]

At 10 or 11 PM they should have issued a STDS.

[JonathanBelles]

At 10 or 11 PM they should have issued a STDS.

It's 11:26 right now.

[Aric Dunn]

they are probably waiting to see if it can hold over night before starting advisories! I dont blame them since systems in this area often open back up rapidly. i imagine if it is still at least at its present organization in the morning they will upgrade, since T-numbers are 2.5
we will see...among other things

没有必要，不要忘了在这里还有来自世界另一端的我们。

There's no need. Don't you forget we, from the other side of the world, are available here in storm2k.

TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
105 AM EST SUN DEC 30 2007

...SPECIAL FEATURE...

THE EASTERN ATLANTIC DEEP LAYER CYCLONIC CIRCULATION CENTER
IS MORE OR LESS IN THE SAME SPOT THAT IT HAS BEEN RESIDING FOR
THE LAST WEEK OR SO. THE SUBTROPICAL CLASSIFICATION NUMBER IS
S-T 2.5. A HURRICANE FORECASTER WROTE A DSAAT BULLETIN AT
29/1900 UTC...THIS FEATURE THAT IS ABOUT 950 MILES SOUTHWEST
OF THE AZORES GRADUALLY HAS BEEN ACQUIRING SOME SUBTROPICAL
CHARACTERISTICS DURING THE PAST DAY OR SO. IT HAS BEEN
PRODUCING GALE-FORCE WINDS...MAINLY TO THE NORTH AND EAST
OF ITS CIRCULATION CENTER. IT IS POSSIBLE THAT IT MAY BECOME
A SUBTROPICAL STORM LATER TODAY AS IT REMAINS NEARLY STATIONARY.
FURTHER TROPICAL DISTURBANCE STATEMENTS WILL BE ISSUED AS
NECESSARY. ADDITIONAL INFORMATION ON THIS SYSTEM CAN BE FOUND
IN HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...
UNDER AWIPS HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC.
SCATTERED MODERATE TO STRONG SHOWERS AND THUNDERSTORMS ARE
FROM 28.5N TO 30N BETWEEN 33W AND 37W. A THIN LINE OF CLOUDS
AND POSSIBLE SHOWERS STILL IS ALONG 25N34W 20N37W 18N40W 13N50W
10N57W 9N60W AND NOT QUITE TO THE COAST OF EXTREME EASTERN/
NORTHEASTERN VENEZUELA AS IT WAS 16 HOURS AGO. PATCHES OF
MULTILAYERED CLOUDS AND POSSIBLE SHOWERS ARE ASSOCIATED WITH
AN ALREADY-DISSIPATED ATLANTIC OCEAN TROUGH...ORIGINATING FROM
THE DEEP LAYER LOW PRESSURE CENTER WITHIN 180 NM TO 240 NM
NORTH OF 17N46W 12N57W 11N65W 13N71W. THE CLOUDS/POSSIBLE
PRECIPITATION ALONG THE WESTERN END OF THIS LINE ARE IN THE
CARIBBEAN SEA. THE CYCLONE SHOULD MEANDER DURING THE NEXT
36 HOURS BEFORE BEING PUSHED TOWARD THE WEST OR SOUTHWEST
BY A DEVELOPING MIDDLE-OCEAN RIDGE ON MONDAY. THE LATE NIGHT
AND EARLY MORNING HOURS OF TODAY MAY BE THE LAST OPPORTUNITY
FOR THIS SYSTEM TO GAIN A BIT MORE ORGANIZATION TO ITS
PRECIPITATION PATTERN AND MAKE THE TRANSITION TO A NAMED
SUBTROPICAL STORM GIVEN THAT THE VERTICAL SHEAR IS FORECAST
TO INCREASE SUBSTANTIALLY LATER TODAY.

[HURAKAN]

Continues to looks subtropical.

[Crostorm]

[Chacor]

Reminds me of a system that's becoming extratropical.

30/1145 UTC 27.1N 35.4W ST2.5/2.5 95L -- Atlantic Ocean




I think that the folks of NHC are not inclined to classify it.It looks ragged.

[wxman57]

New runs. Not much change. However, remember that BAMs are not reliable in the subtropics.
