Re: Tropical Wave in West Africa (Pouch 39L)

Would any Storm2K member care to explain the difference between the GFS, GEFS and GEFS Ensemble Member?
I understand that the GEFS Ensemble member shows the differents runs of the model based on the parameters included in each run, and that the GEFS shows the average run.
Thanks in advance.

The GFS ensemble mean is agreeing with something in track between the Euro and GFS operational so it lends more credence to the Euro track solution

nope. Been consistent and in the same place. Only issue this time is more land interaction

Whats your take on this? Do you side with the GFS solution or Euro solution?

Re: Tropical Wave in West Africa (Pouch 39L)
FWIW...the 12z Euro so far at 168hrs is much much weaker. Barely a trace of vorticity approaching the islands lol

It's back at 50W, just where it was at 0Z

also definitely farther south this run but farther north than the GFS, what the euro has here could be a worst case scenario as it would avoid all landmasses except for a few small islands

Re: Tropical Wave in West Africa (Pouch 39L)
The 12Z ECMWF has an organizing low heading towards the Western Caribbean ready to make a turn northwest and then north which would be a classic October setup. How the run ends below showing 500mb height anomalies:

The one to the west is the one the GFS is showing too and also has an escape route to the north of it where it could go to the GOM and possibly also somewhere in Florida

It appears to me the one further west is Pouch 39L. Do you think that is correct? In any case, it looks like the Euro is coming a bit more in line with the GFS in terms of developing further south.

but not quite as far south as the GFS through the eastern Caribbean so if this comes to pass then we may have a big problem in the eastern GOM and maybe even Florida so heres my area of concern from New Orleans to Fort Myers

Re: Tropical Wave in West Africa (Pouch 39L)
Another thing of worry is we seem to be getting a consensus on 39L developing into a named system in the Caribbean, I sincerely hope this is not the storm that ends the major US landfall drought of 11 years

Re: Tropical Wave in West Africa (Pouch 39L)
what I gather from this is nothing, until we have a system we won't know anything, also euro and GFS has been flip flopping on the high pressure in SE

Re: Tropical Wave in West Africa (Pouch 39L)
What is everyone getting all excited about?
The GFS has a significant tropical cyclone in the NW Caribbean and GoM 300hrs. and beyond.
The Euro barely has a weak 1009mb low in the Caribbean @240hrs.

Ukmet is little stronger now. So it is now coming into view on the Ukmet approaching the middle part of the islands.
So you have all the major models fully on board.

Re: Tropical Wave in West Africa (Pouch 39L)
Wave is building convection on west side tonight as it nears the coast off Africa. The center of the wave axis is further east.

Re: Tropical Wave in West Africa (Pouch 39L)
seems like the 18zGFS is showing more vorticity than the last couple of runs at 40W, that could indicate a stronger system later in the run
