This is the reason why I am not buying a C.A. track towards the EPAC. The ensembles over all favor it staying in the Caribbean side of C.A.

How often are the ensembles correct with potential future forecasts ?

There seems to be some bias going on with the upcoming MJO and the intensity of this wave. It's odd.

It's interesting because the 12z operational kinda splits Eta in 2..one into pac and other in nw caribbean.

Wind field and convection quickly improving.
Axis well defined now.
Appears to be more along the lines of a CMC-forecasted spin-up south of PR tomorrow.
I am not believing that sharp left turn in the forecast track though.
Very likely this will be a deep warm core.

What are you saying? Storms like this can happen in all of August-November. Nothing abnormal.

The sweet spot for it to develop would be under this anticyclone on Saturday

I am going to give a recent example, Zeta. When the disturbance entered the scene in the Caribbean, just about all global models' operational runs were quickly developing a system and shooting it off NE across Cuba into the Bahamas while the ensembles mean kept lowering pressures in the western Caribbean. The same thing is happening with this system, the ensemble means keep lowering pressures in the central and western Caribbean immediately after the globals' operational runs track their developed system across central America. It will not make any sense that another system would develop right away after the first moves across the C.A. Is one or the other. IMO.

In September I remember talking about November surprise during La Niña years.. Very common for there to be a November hurricane in the Caribbean during La Niña. Eg Paloma 2008, Tomas 2010, 2016 had a major that ran in Central America

As I said, Mitch almost touched EPAC waters after moving inland over Central America. Ensemble runs do imply a similar setup(stall over Honduras or even into EPAC before eventually getting lifted)

I remember Mitch, it was supposed to eventually move northward towards the US quicker than what it actually happened, by it staying inland longer than forecasted it was a much weaker system after it re-emerged over water.

I mentioned in a post a few pages back that development could happen as early as this Saturday, but I am thinking Sunday could be the day.

I was referring to the track going against the traditional NE track we get in November.

It moved across the FL peninsula and exited @WPB... If I remember correctly it was @65mph TS... It was moving fast at that time and cool storm to watch that didn’t create a bunch of damage...
