Hi everyone, I've not seen this one being mentioned so far on here, but looks like this one will be flash Gordon!

Doesn't look like becoming that strong as shear is currently causing some problems for TD7, not that suprising mind you given how shear has been in the 06 season so far.

In the long term I suspect this system has every chance of becoming a tropical storm and may well be rpetty close right now to being a tropical storm given the sat.estimates presently on its strength. The latest GFDL now goes for a hurricane after destroying the circulation overnight and the SHIPS want to take TD7 upto a good 55kts. Despite this there is scope for Td7 to become as strong as Florence given the chance of a upper level high being forecast to form nearby Td7 something that Florence lacked and was par tof the reason that Florence took so long to get going. Whatever happens it does look like Td7 could be another long tracker like Florence was.

Track is fairly complicated however. The steering currents suggests its right on the borderline of a col and much depends on just how large of a weakness that Florence leaves to its NE. the NHC and models seem to be moving TD7 into the weakness quite willingly however the models are already assuming a NW motion occuring which means at the very least the system is getting too far north. In all likelyhood a slow movement to the west is most likely under some very light steering currents, prehaps even just a drift at times. I susopect the models are going to be right in that the weakness left from Florence should be large enough to llow a gradual turn to the north and I'd say this has a large possiblty of being a threat to Bermuda...again. There is an outside chance that Td7 will not get far enough west in time to feel the weakness and the ridge could re-build and send TD7 westward again, which would then leave a much higher chance of a USA landfall.

TROPICAL DEPRESSION SEVEN DISCUSSION NUMBER 2

NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072006

500 AM EDT MON SEP 11 2006

CONVENTIONAL SATELLITE IMAGERY DEPICTS SOME IMPROVED ORGANIZATION IN

THE CONVECTIVE BANDING THIS MORNING...PARTICULARLY OVER THE

SOUTHEAST PORTION OF THE SYSTEM. DVORAK INTENSITY ESTIMATES HAVE

INCREASED TO 30 KT FROM ALL AGENCIES WITH THE INITIAL INTENSITY

FOLLOWING SUIT.

THE INTENSITY FORECAST CONTINUES TO BE A BIT OF A MYSTERY. THE

LATEST GFDL RUN NOW INDICATES THAT THE DEPRESSION WILL BECOME A

HURRICANE IN 48 HOURS...SIMILAR TO THE SHIPS MODEL. THIS SEEMS

SOMEWHAT AGGRESSIVE CONSIDERING THE CURRENT NORTHWESTERLY

SHEAR...AND THE POTENTIAL FOR STRONG UPPER-LEVEL SOUTHEASTERLY FLOW

IN AROUND 36-48 HOURS...AS THE LARGE SCALE MODELS INDICATE. IN

FACT...THE GLOBAL MODELS UNANIMOUSLY DISSIPATE THE SYSTEM. THE

OFFICIAL INTENSITY FORECAST IS QUITE SIMILAR TO THE PREVIOUS

FORECAST... SUGGESTING LITTLE CHANGE IN STRENGTH DURING THE NEXT 48

HOURS. AFTERWARD...IF THE DEPRESSION SURVIVES...THE DYNAMICAL

MODELS INDICATE SOME WEAKENING OF THE UPPER EASTERLIES AND IMPROVED

OUTFLOW WHICH COULD PROVIDE AN OPPORTUNITY FOR SOME

STRENGTHENING...WHICH IS REFLECTED IN THE OFFICIAL FORECAST.

INITIAL MOTION IS ESTIMATED AT 290/6...WITHIN THE SOUTHWESTERN

PERIPHERY OF A LOW- TO MID-LEVEL HIGH TO THE NORTHEAST. THE GLOBAL

MODELS ALL INDICATE A WEAK STEERING CURRENT THAT WOULD EVENTUALLY

TURN THE THE CYCLONE NORTHWESTWARD INTO A BREAK IN THE

SUBTROPICAL RIDGE. THE BAM MODELS SHOW RECURVATURE INTO THE

MID-LATITUDE WESTERLIES BY DAY 4. THE GFDL AND THE GLOBAL MODELS

SUGGEST AN ABRUPT NORTHWESTWARD TURN...THEN A MORE NORTHWARD MOTION

AFTER 48 HOURS. THE OFFICIAL FORECAST IS BASED ON BLEND OF THE

BAMS... THOUGH SLIGHTLY SLOWER...AND CLOSELY FOLLOWS THE PREVIOUS

FORECAST.

Hmm, this one may cause some problems for the models however as it has formed west of 50W, USA lanfall is possible.

Having had a look at the synoptic outlook, this system could eventually become a threat to the eastern Carribean if it does not reach 65W within 96 hours.

I know that i said this before, but i believe that this season we will see something remanicent of Hurricane Andrew hitting Florida.

Gordon-to-be, looks even more dull than Florence turned out to be. Okay, maybe if you're in Bermuda right now you'd disagree, but still, we all know the relatively weakness of Florence.

--

Gordon looks weak, I'm sure it'll get named, by Tuesday, but can't see it going anywhere other than where Florence is headed.

I'm not sure that you'd say Florence was that weak mind you Calrissian, esp when Bermuda got quite a few hurricane force gusts and it was close to cat-2 status as well.

As for TD7, yeah its gonna exit the same sort of direction as Florence did as the weakness is not going to replaced nearly fast enough, indeed it looks like TD7 is already moving WNW as Florence exits to its north-west.

Recon is presently inside of Td7 and has found a central pressure of 1006mbs however more importantly, winds upto 47kts at flight level which suggests that we have Gordon right now and an upgrade will occur next advisory. Convection has since weakened a little so how long it'll keep the TS status I don't know but an upgrade to tropical storm Gordon looks probable.

Could end up re-curving further south then Florence did which may allow Td7 to hold onto its pure tropical status for longer then Florence is going to.

As you can see, there is the weakness created by Florence, and as you can see from the chart below, the weakness will of closed in around three days time, given the slow motion of Tropical Storm Gordon i would agree that there will be a similar track to Hurricane Florence however i also think that there is a high likely hood of landfall somewhere south of New York, with quite favourable conditions.

Rwtavn781.gif

As you can see below, the models do not really support me and all favour complete recourvature aside from one which supports the Carribean option, however i have annotated the two tracks which i think are most likely.

storm_07.gif

If Tropical Storm Florence is to take the option of a Florida landfall which is palausable to me, then it must not be more than 65W, 25N, in 48 hours.

Well indeed we do have TS Gordon now for real, here is the navy site:

http://tcweb.fnmoc.navy.mil/tc-bin/tc_home.cgi

By the way, TS Gordon is being inflicted by some shear right now and the LLC is somewhat exposed on the NW side of the convection, the reason seems to be Florence outflow which should keep Gordon pretty clsoe to where its at right now for the next 24-48hrs until Florence gets whipped away to the NE. Despite being upgraded I do have my doubts as to how long Gordon will last as a TS given the shear levels that are being inflicted upon it right now thanks to Florence however I don't see that lasting for more then 24hrs providing Florence hurries on out of there. Despite this there still looks to be shear even whe nthe stronger stuff eases down so I don't expect Gordon to become that strong in the short term at least, but then again the SHIPs do take this upto hurricane status which is quite noteable, even if they have been about 10-15kts too high for every system this year so far.

Intresting track ideas, too early to forecast a decent accurate track but I'd probably punt for the re-curve track, with such great agreement and the obvious weakness caused by Florence I'd say this is almost certainly going to go out to sea, esp as its already moving WNW, also note the offical forecast has it re-curving nearly eastward again which may mean it may stay far enough south for it to stay tropical during its journey eastward across the atlantic for longer then Florence is doing so. Despite the great model agreement a sis expected I'd say ther eis a very small chance for your more northern set-up to occur SB if the ridge builds in faster then expected, but its only a VERY small chance indeed and my full weight is wit hthe models at the moment, no reason for them to be wrong and this track should be one of the easier ones this seasom.

Will Gordon go out with a whimper, or go out with a mighty flash...

(Sorry could resist...)

(ps, models have stareted at 40kts, so Gordon is a 45mph TS right now according to the models.)

Well, as expected we've got name 7'. I suppose there is potencial, but I can't see much coming from this, and even if it does, the track seems Florance bound.

The storm is a little weak on its northwestern side however it has an impressive outflow on its eastern side and convection is doing a good job of wrapping round the centre, as with many small storms, there may be some rapid intensification, personally, i would not be suprised to see a hurricane by morning.

Shear is easing down faster then I expected last night and it seems to have developed a central dense overcast already, has organised suprisingly well overnight and it may well be the case given the impressive Satelite imagery that Gordon is already close to hurricane status, so don't be suprised to see a hurricane today!

Gordon looks impressive this morning, I was expecting it to be 'Flash Gordon' and not last too long.

Here it is this morning, close to being a hurricane! I think it's probably going to the most impressive storm of the season so far.

500 AM EDT TUE SEP 12 2006

THE CENTER IS DIFFICULT TO LOCATE IN INFRARED IMAGERY...AND THERE

HAVEN'T BEEN ANY GOOD MICROWAVE PASSES RECENTLY. CONTINUITY FROM

THE PREVIOUS MOTION WOULD PLACE THE CENTER NEAR THE SOUTHERN EDGE

OF A SMALL BALL OF DEEP CONVECTION. THE ASSUMED INITIAL MOTION IS

320/7...ALTHOUGH IS POSSIBLE THE CENTER IS A LITTLE TO THE

NORTHEAST OF THE ADVISORY POSITION. GORDON IS LOCATED ON THE

SOUTHWESTERN PERIPHERY OF MID- LEVEL HIGH PRESSURE...WITH A

PRONOUNCED BREAK IN THE SUBTROPICAL RIDGE ASSOCIATED WITH FLORENCE

TO ITS NORTHWEST. ANOTHER IMPORTANT FEATURE IS A LARGE UPPER-LEVEL

LOW...LOCATED ABOUT 1000 NMI TO THE EAST-NORTHEAST OF GORDON...THAT

IS MOVING WESTWARD. GLOBAL MODELS INDICATE THAT EVEN THOUGH

FLORENCE WILL BE MOVING OUT...THE WESTWARD-MOVING UPPER LOW WILL

BREAK DOWN THE REMAINING SUBTROPICAL RIDGE TO THE NORTH OF GORDON

AND ALLOW THE CYCLONE TO SLOWLY RECURVE. MOST OF THE DYNAMICAL

MODELS SUPPORT THIS SCENARIO... ALTHOUGH THE GFS IS THE RIGHT

OUTLIER INITIALLY AND CONSEQUENTLY HAS A MUCH SLOWER INTERACTION

WITH THE WESTERLIES. THE OFFICIAL FORECAST IS SIMILAR TO THE

PREVIOUS ADVISORY TRACK EXCEPT A LITTLE SLOWER TO THE NORTHEAST ON

DAYS 4 AND 5 OUT OF RESPECT FOR THE GFS. OVERALL THE TRACK IS IN

BEST AGREEMENT WITH THE UKMET AND NOGAPS MODELS.

DVORAK INTENSITY ESTIMATES ARE 45...55...AND 55 KT FROM TAFB...

SAB...AND AFWA...RESPECTIVELY...AND THE ADVISORY INTENSITY WILL

REMAIN AT 50 KT. THE UPPER-LEVEL FLOW OVER GORDON IS DIVERGENT...

AND THIS FAVORABLE PATTERN IS FORECAST BY THE GLOBAL MODELS TO

PERSIST FOR THE NEXT COUPLE OF DAYS. THE SHIPS AND GFDL INTENSITY

MODELS BOTH BRING GORDON UP TO ABOUT 80 KT IN 48 HOURS...AND THE

OFFICIAL FORECAST DOES AS WELL. ONE POSSIBLE INHIBITING FACTOR

WOULD BE SOME DRY MID-LEVEL AIR THAT COULD BE DRIVEN INTO THE

CYCLONE FROM THE NORTHEAST BY THE UPPER-LEVEL LOW. TOWARD THE END

OF THE FORECAST PERIOD...AS THE CYCLONE BEGINS TO RECURVE

OVER COOLER WATERS AND ENCOUNTERS WESTERLY SHEAR...THE

INTENSIFICATION OF GORDON SHOULD BE DONE.

Basic track idea still holds from last might still so I see no reason why I should bother re-typing the same stuff again!

One small thing is the Gordon will probably end up about 1 degree further west then is expected by the models thanks to Gordon deepning and latching ont othe deeper flow which is more of a NNW rather then N/NNE flow as it is in the shallower flow.

Gordon looks very good on Sat.imagery right now and has probably strengthened since this afternoon after some slight SE shear has levelled off the strength of Gordon but its structure ha simprvoed again slightly since then so probably the winds wil lbe upped to 65mph next advisory unless Gordon rapidly strengthens which is possible I'd guess. looking at the waters ahea dof it plus the possiblty of the Se shear remianing, i'd probably say that Gordon has every shot at becoming a hurricane however I'd dare say not much beyond that because the seas aren't exactly amazingly warm in that part of the world its heading plus the upper air condtions are probably only condussive for steady development.

THE OVERALL SIZE OF GORDON HAS EXPANDED AND THE SYSTEM HAS IMPROVED

IN APPEARANCE DURING THE DAY WITH OUTFLOW WELL ESTABLISHED IN THE

EASTERN SEMICIRCLE AND IMPROVING IN THE SW QUADRANT. SATELLITE

INTENSITY ESTIMATES FROM TAFB...SAB AND AFWA ARE ALL 55 KT...WHICH

IS THE INITIAL INTENSITY FOR THIS ADVISORY.

BASED ON THE LATEST GEOSTATIONARY AND MICROWAVE SATELLITE FIXES...

THE INITIAL MOTION IS NOW DUE NORTH...360/6. GORDON REMAINS ALONG

THE SOUTHWESTERN PERIPHERY OF A NARROW MID- TO UPPER-LEVEL RIDGE

WITH A PRONOUNCED BREAK ASSOCIATED WITH FLORENCE TO ITS NORTH. A

LARGE UPPER-LEVEL LOW...LOCATED ABOUT 950 NMI TO THE NORTHEAST OF

GORDON IS MOVING WESTWARD BUT IS FORECAST TO WEAKEN TO A SHEAR AXIS

WELL TO THE EAST OF GORDON...MAKING IT LESS LIKELY TO HAVE AN

IMPACT ON THE TROPICAL CYCLONE. AN UPPER-LEVEL TROUGH MOVING THROUGH

THE CENTRAL U.S. IS FORECAST TO MOVE EASTWARD AND CAPTURE A

NORTHWARD-MOVING GORDON BEYOND 72 HOURS AND ALLOW RECURVATURE INTO

THE WESTERLIES. ALL OF THE DYNAMICAL MODELS SUPPORT THIS SCENARIO.

THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ADVISORY AND IS

CLOSE TO THE DYNAMICAL CONSENSUS.

WATER VAPOR IMAGERY SHOWS VERY DRY AIR WEST OF THE AFOREMENTIONED

UPPER LOW WHICH...AS NOTED ABOVE...IS BECOMING LESS OF AN

INHIBITING FACTOR FOR THE INTENSIFICATION OF GORDON. THE OFFICIAL

INTENSITY FORECAST IS A BLEND OF THE SHIPS AND FSU SUPERENSEMBLE...

BUT NOT QUITE AS AGGRESSIVE AS THE GFDL...WHICH STILL MAKES GORDON

A 90 KT HURRICANE IN 72 HOURS. TOWARD THE END OF THE FORECAST

PERIOD...AS THE CYCLONE BEGINS TO RECURVE OVER COOLER WATERS AND

ENCOUNTERS WESTERLY SHEAR...GORDON SHOULD BEGIN WEAKENING.

1100 PM EDT TUE SEP 12 2006

THE CLOUD PATTERN HAS BECOME MORE SYMMETRIC WITH DEEP CONVECTION

SURROUNDED BY A WELL-DEFINED CURVED BAND. MORE SIGNIFICANTLY...

THERE HAS BEEN AN INTERMITTENT EYE FEATURE ON CONVENTIONAL

SATELLITE IMAGERY WHICH WAS ALSO OBSERVED IN MICROWAVE DATA.

DVORAK T-NUMBERS ARE BETWEEN 4.0 AND 4.5 FROM ALL AGENCIES WHILE

OBJECTIVES NUMBERS REACHED 5.4 AROUND 0000 UTC. THE OBJECTIVE

NUMBERS HAVE DECREASED SINCE THEN...BUT STILL SUPPORT HURRICANE

STRENGTH. GORDON IS DEFINITELY STRONGER THAN EARLIER TODAY AND THE

INITIAL INTENSITY IS INCREASED TO 65 KNOTS. ALL AVAILABLE GUIDANCE

SUGGESTS THAT THERE SHOULD BE SOME ADDITIONAL STRENGTHENING BEFORE

THE SHEAR INCREASES IN A COUPLE OF DAYS...AND SO DOES THE OFFICIAL

FORECAST.

GORDON IS MOVING NORTHWARD OR 360 DEGREES AT 8 KNOTS. THE CYCLONE IS

ALREADY ON THE NORTHWESTERN EDGE OF THE SUBTROPICAL RIDGE AND READY

TO BECOME EMBEDDED WITHIN THE MID-LATITUDE WESTERLIES. HOWEVER...

THESE WESTERLIES ARE FORECAST TO WEAKEN GRADUALLY...THEREFORE NO

SIGNIFICANT INCREASE IN FORWARD SPEED IS ANTICIPATED. THE OFFICIAL

FORECAST IS BASICALLY IN THE MIDDLE OF THE TRACK ENVELOPE. ONLY THE

UK MODEL ACCELERATES GORDON TOWARD THE NORTHEAST DURING THE LAST

PORTION OF THE FORECAST. GORDON IS NO THREAT TO LAND.

I've got to be quick this morning, but gordon looks pretty good, decent structure with a nice outflow and a decent CDO as well, quite akin to what Florence looked like when it became a minimal hurricane. I suspect that Gordon has every chanc eof getting upto the same sorts of strength as Florence did before it start to re-curve into water with less heat content and should start to weaken in about 96hrs.

Gordon looknig very good now, a solid eye has emerged and is by far the best looking system this year, Gordon isn't going to be a threat to land but its not a ugly system either.

http://icons.wunderground.com/data/images/at200607_sat_2.jpg

Winds now upto 80kts which is the same strength as Florence at its peak however given the way the eye has cleared out recently and the good looking pattern this may be a under-estimate and I'd say 85-90kts is probably more fair, which would make it a cat-2 in the SS scale. I'd take a guess given the heat content that it has a shot at reaching category-3 and be our first major hurricane of the 06 hurricane season. Much above that will depend entirely on whether the shear is low enough however the system is small which is a good thing for these sorts of storms as they require lower heat content to get upto those cat-3/4.
