Interresting Swirl at 13N 52.5W

#1 Postby Gustywind » Thu Nov 01, 2007 9:12 am

Hi everbody:D, in my last topic i was speaking about "Interesting ITCZ activity between 50-55W", whereas two days have passed, and it seems that as Bvigal told me in this last reply of my ex topic...that things have changed(tkanks for her trained eyes :P :wink: ) and i'm agree with her....and there's a swirl or maybe a low trying to show some moderate activity this morning and Bvigal has wel resumed the situation : " There is a swirl now near 13N 52.5W, seen clearly on all satellite loop views. Actually this looks like a low". It looks like a C shape for me beginning to wrapping in my humble opinion ( correct me if m'im wrong...?! 8-)tkanks :cheesy: ).

8amTWD: "A CUT-OFF UPPER LOW IN THE TROPICAL ATLC NEAR 12N52W IS PRODUCING A SMALL AREA OF CLOUDINESS AND ISOLATED SHOWERS FROM 11N-14N BETWEEN 50W-53W."All in all, we should have maybe something to watch ,if this area can support sufficient convection, but we're very very far away from that for the moment, let's see if this convective area persists first and by extension if upper conditions can support something .... :) but given the Olympics SHEAR GAMES ahead of this area i'm a little dubious for a gold medal of hope but who knows :idea: :?: :roll: :P :eek: :roll: :cheesy: :darrow: http://cimss.ssec.wisc.edu/tropic/real- ... g8shr.html 40 or 50 kts of shear ahead the system for my untrained eyes :double: or my eyes are deceiving me :double: :eek: not a simple journey with these hurddles of shear :grrr: :eek:

There's a slight window right now where is localized this area, but after that ahead near the islands ...awesome shear is occuring given this chart :eek:

For the rest of the season we should watch the Western Caribbean and subtropical Atlantic. For the rest of the basin the season is pretty much over.

How can said that? Hope you're right because the last feature was Noel and beginning his trip in the atlantic Ocean, i assume that you're reffering about climato? if it's that ok i'm partially agree with you:D but ometimes in some season the rule is that there's no rules :D :wink: and given what i see for the moment this season "all the water "was coming from the east atlantic :cheesy: so i in my humble opinion i will be more prudent , i observe in all directions ( west carib east carib, subtropical)for all the seasons in all period ( November in this case)... each season is unique :P so we will see what you're assuming "For the rest of the season we should watch the Western Caribbean and subtropical Atlantic. For the rest of the basin the season is pretty much over" :wink:

Yeah absolutely Sanibel partially dry... but trying to wrap too :) :darrow: we will see if this tinny swirl persists in this high shear environnement 8-)

Yeah you're on climato that was what was tkinking about, but reality when there's something it's other thing hurakan (LENNY 1999) we shoud not bet on that in my humble opinion :D :cheesy:

This has all the earmarks of an ULL. Upper Level Winds on WV shows a CCW rotation while QuikSCAT and ASCAT show straight line winds with no rotation. CIMSS shows no organization at this point.

A more interesting area is the mid Caribbean. It appears from QuikSCAT that there may be a surface trough. Some convection is firing here and Noel is pulling up moisture from the ITCZ to fuel it. There is also a broad UL Ridge as well to support outflow.

Remember that in 1999 we saw at least 5 giants and some of them were long-tracking Cape Verde Hurricanes. This indicates that the weather pattern was favorable for hurricanes, which has been mostly inexistant in 2007.

[quote="HURAKAN"]Remember that in 1999 we saw at least 5 giants and some of them were long-tracking Cape Verde Hurricanes. This indicates that the weather pattern was favorable for hurricanes, which has been mostly inexistant in 2007.[/quote

Remember that in 2007 we saw 2 giants of cat 5 in less than 2 weeks, and that's history if you miss and an episode :wink: and one of them were Dean a long-tracking Cape Verde Hurricane for my untrainded eyes or my eyes are deceiving me :) it's history, so this indicates that the weather pattern was favorable for hurricanes during a period ,which has been mostly existant in 2007 :D :lol: :P . So given what you are assuming, i can't believe in that because all season is unique and believing in that ...means for me that one day a man will walk on the sea too be serious a moment that's pure
stupidities i can trust in that :spam: :eek: :spam:. In my modest opinion canes can form anywhere anytime...and against mother nature we should have a wide view of the multiples scenarios who can occur and by extension life :) ...for example when a meterological feature decides to explode on your country particulary an island ...we don't have to much time to waste that time, because it's really a privilege by thinking that there's a part of a bassin who should be inactive or not, climato it's funny it's statistics ...yeah but for a moment :cheesy: life is not based on figures even more with hurricanes in terms of protection of life etc :double: :roll: :spam: in my humble opinion , so if in 1999 for Lenny the forecasters were ok to predict this nasty tenacious,awesmome feature (Lenny 19th November 1999 with an amazing flooding action :eek: !) i would have been glad :D :D , whereas before that any of them were saying that, (but ohhh after September a season is ended :grr: as a consequence there's no rules with nature we observe what happens i stay modest :D :wink: hope your are too, but i advise you too if it was the contrary Hurakan maybe i'm wrong i hope that :P 8-) ) !
In a conclusion say that "For the rest of the season we should watch the Western Caribbean and subtropical Atlantic. For the rest of the basin the season is pretty much over".For the rest of the season we should watch the Western Caribbean and subtropical Atlantic. For the rest of the basin the season is pretty much over".
So, for a carib resident remembering Lenny ( November 1999, José October 1999) and with all the incertitudes, mysteries during a cyclonic season, who is always for my little untrained eyes :eek: [color=#FF0000]unique
...given that... consequently...that makes radically no sense for me[/color] :oops: :double: in humble opinion :spam: :wink: :) i emphasize on the fact that if you were living in a small island like Guadeloupe you would have a different forward angle for sure about this :"For the rest of the season we should watch the Western Caribbean and subtropical Atlantic. For the rest of the basin the season is pretty much over.
For the rest of the season we should watch the Western Caribbean and subtropical Atlantic. For the rest of the basin the season is pretty much over."/color]. Hope that i put some clearance in my point of view Hurakan :D and don't forget that Mother Nature has always her rules, her plans in store , we're nothing on earth [color=#FF0000]especially in a island sometimes we forget it here
. To sum up , if you know her better than her...it's another story :eek: :lol: :lol:, so tell me what will happen for 2008, that's the 10000000$ question :spam:
Nice Regards in whole humility Gustwind:P :) :D 8-)

TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
205 PM EDT THU NOV 01 2007

TROPICAL WEATHER DISCUSSION FOR NORTH AMERICA...CENTRAL
AMERICA...THE GULF OF MEXICO...THE CARIBBEAN SEA...NORTHERN
SECTIONS OF SOUTH AMERICA...AND THE ATLANTIC OCEAN TO THE
AFRICAN COAST FROM THE EQUATOR TO 32N. THE FOLLOWING INFORMATION
IS BASED ON SATELLITE IMAGERY...METEOROLOGICAL ANALYSIS...
WEATHER OBSERVATIONS...AND RADAR.

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1715 UTC.

...THE ITCZ...
ITCZ AXIS IS CENTERED ALONG 10N14W 8N22W 5N33W 8N43W 4N53W.
SCATTERED MODERATE CONVECTION IS WITHIN 220NM EITHER SIDE OF THE
AXIS BETWEEN 18W-24W. SIMILAR ACTIVITY IS WITHIN 150NM N AND
90NM S OF THE AXIS BETWEEN 24W-32W. A TROUGH IS EMBEDDED IN THE ITCZ ALONG 40/41W FROM 5N-16N...THAT IS GENERATING ISOLATED SHOWERS/TSTMS WITHIN 90 NM OF THE AXIS. THIS MAY ACTUALLY BE THE TROPICAL WAVE THAT APPEARS TO HAVE PASSED DAKAR AROUND 12Z OCT 27. HOWEVER...GIVEN ITS RATHER POOR SATELLITEAPPEARANCE HAVE OPTED TO MAKE THE FEATURE A TROUGH.
