Actually the LLC is getting less defined and convection is disorganized and well-removed from the center.

:D Good Morning all you tropic Fans , I have a question I cannot find a model plot for 97l Can someone tell me where to find one? Are they updated for Today Yet? Thank You, Marilyn
Never Mind i just saw the one on the previous page looks as if this May fish! of course as of Yesterday that is.

...still lookin like it will be a fishy lol...

on satellite it looks like it has started a more WNW path so I think its jog to the WSW is over. not sure what to think of it strengthwise... most of the convection still on the east side of the storm. right now its a debate in my head whether it will develop or not... I'm not even going to think about anything higher than 50kt at this point

8-) I'm liking those numbers! (thanks for making them change it, Luis! - now...can you do something about the quick switch we're having to rain and ugh? I have things to do today!)

Rain will be the rule today for us as a strong wave passes south of PR.

Invest 97L is finally passing through the 40W longitude line this morning. As I had mentioned a few days ago, this means that the system is now moving over warmer SSTs (82*+), unstable air, and is being less influenced by the Upper-Level Low NE of it.

Satellite images suggest that the VIGOROUS LLC that had been present earlier has become somewhat tighter in nature and is not as broad as it used to be. Usually this indicates that the system is soon to consolidate. I will give it another 24-48 hours before we see it being upgraded a tropical depression as it gradually moves to a better environment for development. That being said, the system is likely producing TS force winds underneath the convection. Since the convection is far removed from the center (mainly due to dry air to its west and moderate wind shear), it is NOT being upgraded at this time.

One possibility, which is not out of the question, is that a MUCH tighter LLC develops just W-NW of the convection. This could happen as the broad LLC contracts somewhat.

The system will likely miss the northern Lesser Antilles, but the longer it takes to fully consolidate, the farther west it will go. Until it is NORTH of the latitude of the islands, DON'T stop watching it!

BTW, the tropical wave which moved off the coast a few days ago, has (for some inexplicable reason) been devoid of convection for a LONG time. I can't find a reason why this is happening since it is located over warm SSTs and the SAL is not impacting it at this time. The wave axis is still there and will have to be monitored because *apparently* conditions are favorable.

Another wave is emerging off the coast, but I won't comment much on it, except for the fact that if it stays far enough south (10-15*N), it will have a better chance of sustaining itself.

Great points Hyperstorm, water only get warmer from 82 to 86 until the Bahama's. Was not Ivan the lowest forming Hurricane in Latitude last year??

Thanks for your opinion, cjrciadt.

Ivan was actually the farthest south a major hurricane has developed in the Atlantic Basin. If I remember correctly, Hurricane Isidore many years ago, developed farther south than Ivan did as a hurricane. I'll have to to refresh my memory on that.

I wonder why the T#s fell though... it's looking a lot better actually...

question: do you think 97L will reach 50W before or after 20N... or never at all (recurve)?

A WESTWARD-MOVING TROPICAL WAVE IS LOCATED ABOUT 1400 MILES EAST OF
THE NORTHERN LEEWARD ISLANDS. THIS SYSTEM HAS BECOME A LITTLE
BETTER ORGANIZED TODAY...AND ENVIRONMENTAL CONDITIONS ARE SOMEWHAT
FAVORABLE FOR A TROPICAL DEPRESSION TO FORM DURING THE NEXT COUPLE
OF DAYS.

BTW 97L still looks very organized, and looks already like a decent TD.

the NRL site hasnt put up TD 13 and this doesnt say "noname" so I guess it's being kept as an invest for now...

the TWO should cover it though
