INVEST 95L: NE Atlantic : Discussions & Images

[cycloneye]

On NRL is not yet because there are problems in the site with the pics that haved not been updated so I assume as soon they fix it 95L will appear.But the models came out,so its a guarantee that 95L is up.

Original thread.

[TheEuropean]

I just posted the first models in the original thread:

viewtopic.php?f=31&t=99549

This has a real chance to become a second Zeta.

There are some problems with images in other sites that are not updating this morning so here is a image from ramsdis that are updated.

Look at the BAMM track.

[dixiebreeze]

Headed right for you, Luis! Remarkable on Dec. 29.

[dixiebreeze]

In the IR floater loop 95 is really firing up.

[HURAKAN]

Looks good for subtropical although the center is still very broad.

[Cyclone1]

I saw this coming, but still I'm shocked at an invest on December 29. It's just not right.

Wow... Wake up, NHC we got ourselves a fighting season.

[Tstormwatcher]

Wow, this has surprised me. Models show it moving southwest. Wonder what its chances will be for becoming tropical?

[JonathanBelles]

Based on what the calendar says, I dont give this much chance. Shear is falling in its modeled path, but is still high. Water temps are marginal, but with storms this time of year like Epsilon and Zeta, I think a storm could survive in these conditions. Any growth will be slow, if at all.

[Cyclone1]

SouthWEST? Havn't had a chance to look at the models, but that's very Zeta-esque. Honestly, I give this almost a 90% chance of becoming either Pablo or Arthur in the next few days.

Per the NHC:

THE ATLANTIC OCEAN...
INTERESTING FEATURE FOR THE DAY IS THE DEEP CYCLONE CENTERED
NEAR 27N38W. THIS SYSTEM HAS REMAINED STATIONARY FOR A COUPLE OF
DAYS AND ORGANIZED CONVECTION IS DEVELOPING IN A COUPLE OF BANDS
LOCATED TO THE EAST OF THE CENTER. QUIKSCAT WINDS SUGGEST THAT
THERE ARE SOME GALE FORCE WINDS ALONG THE NORTHERN SEMI-CIRCLE
AND SE QUADRANT OF THE SYSTEM...THAT SEEMS TO BE ACQUIRING SOME
SUBTROPICAL CHARACTERISTICS. MOST OF THE COMMON TYPE OF
SUBTROPICAL CYCLONE IS AN UPPER-LEVEL COLD LOW WITH CIRCULATION
EXTENDING TO THE SURFACE...AND THIS IS THE CASE. ACCORDING TO
THE UW-CIMSS PRODUCTS...VERTICAL SHEAR ON THE SYSTEM IS
RELATIVELY WEAK...BUT THIS LOW-MODERATE SHEAR ENVIRONMENT MAY
ONLY LAST FOR ANOTHER DAY OR SO BEFORE STRONG UPPER WESTERLIES
IMPACT THE SYSTEM WITH THE APPROACH OF A VIGOROUS SHORT-WAVE
TROUGH. THE CYCLONE SHOULD MEANDER IN PLACE FOR THE NEXT 24-36
HOURS OR SO. SOME OF THE MODEL GUIDANCES MOVE THIS SYSTEM TO THE
SW ACROSS THE OPEN OCEAN WATERS. ELSEWHERE...THE W ATLC REMAINS
DOMINATED BY RIDGING WITH THE MID AND UPPER AXIS EXTENDING NWD
FROM THE CARIBBEAN THROUGH BERMUDA. A JETSTREAM BRANCH IS RIDING
ON THE N PERIPHERY OF THIS ANTICYCLONE BRINGING SOME UPPER LEVEL
MOISTURE/HIGH CLOUDS INTO THE W ATLC...BUT MAINLY N OF 30N. AN
UPPER TROUGH ALSO REMAINS STUCK OVER THE CENTRAL ATLANTIC
EXTENDING SW FROM A CUT-OFF LOW NEAR 27N38W TO THE WINDWARD
ISLANDS. A TROPICAL JETSTREAM RUNS FROM THE BASE OF THIS TROUGH
ALL THE WAY TO THE NE TO THE WEST COAST OF AFRICA CROSSING JUST
N OF THE CAPE VERDE ISLANDS. WV IMAGERY SHOWS A BAND OF
TRANSVERSE HIGH CLOUDS ASSOCIATED WITH THE JET.

[Coredesat]

I had mentioned in the old thread that the globals were deepening the system somewhat, then moving it rapidly west-southwest while weakening very rapidly. Looks like that's what the tropical models are thinking, as well.

[Coredesat]

ACCORDING TO
THE UW-CIMSS PRODUCTS...VERTICAL SHEAR ON THE SYSTEM IS
RELATIVELY WEAK...BUT THIS LOW-MODERATE SHEAR ENVIRONMENT MAY
ONLY LAST FOR ANOTHER DAY OR SO BEFORE STRONG UPPER WESTERLIES
IMPACT THE SYSTEM WITH THE APPROACH OF A VIGOROUS SHORT-WAVE
TROUGH.

This is probably why the NHC isn't incredibly interested in this system at the moment.

Looking less frontal by the hour.



Of course, where this is, naming it STS Pablo would be purely an academic exercise.

Apart from tracking it SW towards the Leewards,it not does much with it intensitywise.
