Re: Possible SW Caribbean Development
Really something to see the gfs be so persistent with developing a tc in the western Carib for many many runs only to drop it. I am still in the development camp for now but that may change during the next couple of days we will see.

Icon has not been a good model due to having a tendency toward fake storms, especially when on its own.

Re: Possible SW Caribbean Development
Still no development, although the disturbance is still there. What is the GFS seeing that kills this?

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

We’ve seen the GFS and GEFS do this before in the W Car in October with similar extreme persistence only to later say “I fooled you”. Just look back at some past October threads here at this forum.

The W Car TC so far is just a model cartoon. So, nothing has been killed since it has yet to exist.
Through 180, nothing on the 12Z GFS.

Maybe the disturbed weather in the Bahamas? Whatever gets going there will slowly drift in the direction of where this was supposed to head to. While models earlier just gave this potential system just increased moisture but nothing organized like now. Also, the models have backed off on how strong this system would develop in the early stages, which would had eliminated the impact of the Bahama system. A weaker system will feel the impacts.

If I had a dollar for every time this forum has attempted to kill off a modeled storm only for it to develop regardless, I wouldn't have to worry about my college expenses.

Thank you for saying that. If conditions are right you can’t question Mother Nature despite what computer is saying

GEFS support has also been vanishing albeit in a more subtle manner. The GEFS has a genesis bias.

Larrywx, it's not the same. The GFS ghost of the past was the only model onboard and it would keep pushing back development outside 240hr. This was different in that you had CMC on board and the time-frames were inside 240. Now you have 12zIcon and just checked 12 CMC onboard so it is not a ghost.
We might still be fooled here but not because we fell.for the same GFS antics.

Yet another word to overuse--ghost. Let's wait because, as the great philosopher, Yogi Berra, once said, "It ain't over till it's over."

Re: Possible SW Caribbean Development
NHC is at 30% through Day 5 with the lemon further W than the GFS was teasing for days. The 12z GFS today has the energy but does not develop and send it right into Central America.

Both the ICON and CMC have a history of being genesis happy. If/when either the Euro or UKMET has something, I’ll become bullish.
12Z UKMET says no W Car genesis through 12Z on 10/24.

Euro couldn't see a TC outside of 48 hours this year unless it strolled up and smacked it in the face.
