You want more information? Look no further than San Juan FAD when a wave is in the Atlantintic.

From the 11 pm discussion:

THE MULTIPLE VORTICITY CENTERS IN SECOND WAVE UP STREAM FROM
US...THE FIRST IS NEAR 58 WEST...ARE NOW BECOMING MANIFEST. THESE
CENTERS...MENTIONED IN A PREVIOUS DISCUSSION...HAVE BEGUN TO
SEPARATE AS EVIDENCED BY DIVERGING CONVECTION CLUSTERS. ONE PART OF
THE CONVECTION NOW APPEARS AT 11 NORTH 50 WEST...AND ONE PORTION OF
THE CONVECTION IS NEAR 16 NORTH 43 WEST. IT MAY BE THAT THE REASON
THAT THE MODELS SHOW SO MUCH NORTHERLY MOTION OF A DEVELOPING
TROPICAL SYSTEM THAT THEY DRAG UP THROUGH 20 DEGREES NORTH AT 57 TO
60 WEST SOMETIME BETWEEN MONDAY AND TUESDAY IS THAT THEY WERE
FOLLOWING THIS LATTER PIECE OF ENERGY. OTHER MODELS SHOW A MORE
WESTERLY TRACK AND BELIEVE THAT THIS COULD BE THE MORE WEST-ADVANCED
CONVECTION THAT IS HOLDING SOUTH AND THAT MAY PASS SOUTH OF US ON
SUNDAY OR SUNDAY NIGHT. IT IS CURRENTLY NOT CLEAR THAT EITHER WILL
DEVELOP IMMEDIATELY...NOW THAT THEY HAVE SPLIT...NOR IS IT CLEAR
THAT EITHER WILL AFFECT THE LOCAL ISLANDS. THIS WILL HAVE TO BE
MONITORED FURTHER. CONDITIONS ARE FAVORABLE FOR DEVELOPMENT...BUT
MODEL SOLUTIONS FOR THE UPPER AIR SUGGEST THAT THE SYSTEMS MAY OUT
RUN THE ANTICYCLONES THAT HAVE MADE CONDITIONS SO FAVORABLE.

New 0Z guidance of GFS/GFDL do not develop this system any further.

Deep convection has developed over the LLC near 9.5/52...The system looks more organized then it did earlier.

Are we looking at the same thing??? The 0z is still showing it form into a low and pass through the Fl straits, and into the GOM and into mexico...

What really caught my attention was the MONSTER trough that dips out of canada as the next storm after that approaches the bahamas, consequently sweeping it and the ridge out. (GFS, overdoing the recurvature again? i hope not.. )

What are your thoughts on these two systems Floydbuster?

Well..there are three IMO.

The system north of Puerto Rico, reminds me a bit of Hurricane Humberto's start in late September 2001. Humberto formed in fart due to some of the outflow/convergence/mess Hurricane Gabrielle had left behind. I believe, based on the models I have seen, this system should move westward...a potential Florida/Gulf Coast threat.

Invest 95L imo, is a monster in the making...for the Caribbean Sea and potentially the United States.

The wave behind 95L bears watching too.

I agree Floydbuster. I think 95L is developing right now around 9.5/52 west. It has developed a good area of convection on top of a increasely organized LLC/cirualtion. Banding is improving. I expect it will go westward or west-northwest. In it will not turn away from the islands like some models think it will. A Emily like system going through the caribbean is my thinking.

As for the system north of the Islands a "Katrina" movement. Which a westward movment for the next 36 hours. In which will likely hit Eastern Florida kind of like the Gfs been showing for the last few runs.

The system behind it could also develop but we will see.

So lets see.
95L could become the P storm...
The system north of the Islands the S storms.

Matt are you saying you think it will take a path simular to Katrina and be a monster like she was?

No monster but a westward path is likely...But of course who would of thought tropical depression 10. Would of done what it did???

Satellite imagery this morning show that 95L, which is located several hundred miles east of the Windward Islands, has not become any better organized overnight. In fact, the system is beginning to outrun its own anticyclone as very well suggested by the NWS San Juan last night. The system started showing signs of eventual outrun yesterday afternoon as the energy was being drawn toward the NE.

Convection has deepened overnight, but before you say it's better organized, you have to remember to look at the overall pattern over and just ahead of it to actually predict strengthening or weakening. The pattern shows moderate westerly flow impinging on the system disrupting its core. There are no signs that this westerly flow will weaken anytime soon.

Based on this information, 95L will have a tough time developing significantly before it reaches the islands contrary to what intensity models say. It could become a tropical depression as it approaches the islands, but atmospheric conditions really don't support any significant strengthening.

The disturbance to the east of 95L did not persist overnight and will probably not amount to much as it is not associated with any type of forcing mechanism...

You're saying 95L has outrun its convection? It looks to me that this morning, there's a slight rotation right under that convection.

skysummit...

The system is outrunning the anticyclone that was keeping it under some light shear yesterday. That being said, if the system SLOWS down significantly, it may actually keep itself under a marginally favorable environment until the anticyclone catches up with it. This morning, there are signs that the system is slowing down, but we'll see if it persists.

If that's the case, that usually means that the system is ready to make drastic changes in its course. It could end up strengthening more and moving NW before it reaches the islands if it slows down further...

This is the worst case scenario as far as increased risk to the U.S. imo. If it were to develop rapidly prior to 55W and move NW, it would have amuch better chance to recurve. However, a TD developing between the Lesser Antilles and 55W moving into the Caribbean on a WNW track this time of year could easily pose a threat of a major to the U.S. down the road.

W/CENTRAL ATLC TROPICAL WAVE IS TILTED SW/NE ALONG 6N53W 14N51W
21N48W MOVING W 10-15 KT WITH A 1011 MB LOW ALONG THE NEAR 10N.
ALTHOUGH THE WAVE IS WELL DEFINED THE LOW LEVEL CENTER IS
ELONGATED ALONG THE WAVE AXIS AND RATHER ILL-DEFINED. WAVE IS
HAS ROUNDED THE BASE OF AN UPPER LEVEL RIDGE. THIS SYSTEM HAS
THE POTENTIAL FOR TROPICAL DEVELOPMENT OVER THE NEXT DAY OR TWO.
SCATTERED MODERATE/ISOLATED STRONG CONVECTION IS NEAR THE LOW
WITHIN 90 NM OF LINE FROM 9N51W-11N56W. CLUSTERS OF SCATTERED
MODERATE/ISOLATED STRONG CONVECTION ARE WITHIN 150 NM OF LINE
FROM 11N51W-16N44W.

Sooo uhh Floyd are you errr saying that Humberto actually formed in a fart from the mess left behind by Gabrielle???

I have heard of the tropics being messy but that is taking it too far....

Happy Friday, everybody :A:

95L is bing sheared now, like all other MDR systems since July

The regions of development have been more consistent with an el nino like year. We need to not look at systems in th MDR since there is very strong shear there

watch the system north of PR

I have to say, I'm glad to hear Derek say that about our friend 95L. I hope he stays away and stays weak. (95L, not Derek :lol:)
