Re: Pouch PO10L SW of CV islands
Although dry air is present, models continue to be aggresive with this pouch vorticity. Here a nice GFS graphic.

Re: Pouch PO10L SW of CV islands
Doesn't look as impressive as it did yesterday, and as said earlier NOAA has removed the surface low from their 06Z analysis - right now it's just a broad circulation with not much convection but lots of dry air around it, and as KWT said if this were one month from now the outcome might have been different:

right now both that and the wave passing through the Lesser Antilles do not seem very impressive - but neither does Don, for that matter...

Re: Pouch PO10L SW of CV islands
The Low is back!!! TAFB at the 12z surface analysis placed back the low.

Re: Pouch PO10L SW of CV islands
From the predict team,here is their latest synopsis of P10L.
http://www.met.nps.edu/~mtmontgo/P10L.html
SYNOPSIS 2011072800
P10L
ECMWF: Relatively smooth west-northwest track of a distinct pouch.
GFS: Beginning to lose its "ITCZ excitation" storyline. Although the pouch initially tracks south of west with a slight weakening, the evidence for an ITCZ excitation is not so obvious. P10L is a large, distinct pouch that then moves west-northwest and actually strengthens slightly as it enters the Caribbean.
UKMET: Except for a early "dip" to the south, the track is to the west-northwest with gradual intensification.
NOGAPS: Slower than other models, but NOGAPS still maintains a distinct pouch to 120 hours.

FWIW I would not be the least bit surprised if it tries to form west of say 50-55W, the same area Don flared up, howev er I'm not convinced conditions in the E.Caribbean are going to be any better then they were for pre-Don.

Re: Pouch P10L SW of CV islands - It has a Low Pressure
If it were not for Don, I would be all over this system. I will call her "pre-Emily." This system has what it takes to be a long track storm West of 50W. I will elaborate later. Back to Don.

Re: Pouch P10L with low SW of CV islands
The Canadian continues to develop this wave,although it does so near the islands and less strong than the past 00z run.

Yea, that's July for ya. I can only imagine that once we get to August, these struggling systems that develop will no longer
be struggling.

Re: Pouch P10L with low SW of CV islands
2 PM TWD:
TROPICAL WAVE IS ANALYZED FROM 05N38W TO 14N33W MOVING W AT
15-20 KT. A BROAD LOW-LEVEL CYCLONIC CIRCULATION IS NOTED IN THE
VICINITY OF THE WAVE AXIS FOCUSING ON A 1010 MB LOW CENTERED
NEAR 07N38W. AN AREA OF INCREASED TOTAL PRECIPITABLE WATER ALSO
COINCIDES WITH THE WAVE AXIS FROM 08N-15N BETWEEN 30W-38W.
SCATTERED MODERATE CONVECTION IS OCCURRING FROM 09N-12N BETWEEN
33W-39W.

Re: Pouch P10L with low SW of CV islands
Sea surface temperatures have warmed significantly in the past couple of weeks. The water along this wave's path is between 28-30C. With light shear, the only obstacle is going to be any dry air that's around:

Well it seems were going to get Emily, but at what point/timeframe?

Most models develop it east of the antilles, so by the weekend or early next week.

IT is looking quite impressive this afternoon. vorticity is increasing along with deep semi-organized convection building. would be very surprised if at the 8pm NHC does not say anything..

Watch the southern portion around 39w below 10n. convergence is high and the vorticity good. would be the likely area for a more defined LLC to develop over the next day or two
