It looks like the 0zGFS is not going to develop this, it tracks over Florida this run

Model support is there from GFS Legacy, Euro, Canadian, Icon. Also may be flipping the switch as there is another possible storm is on deck

Pattern reminds me a little bit of the development of Hurricane Gert in mid-Aug 2017.

Wave axis is over the Lesser Antilles.

I'd say theres a good chance the legacy GFS is onboard showing a hurricane north of the Bahamas next weekend!

The last sentence from the morning discussion about this wave by the San Juan NWS is what we want to see here.

Generally speaking, this tropical wave that will be affecting the
area during the first part of the work week promises to bring
beneficial rains to areas that have been suffering from significant
drought conditions during the last several weeks to months.

Idk.. the lower half of the wave seems to have the most vorticity by far. the models have been showing it farther north. really looking more like a NW carrib wave.. it should start turning NW shortly. so will see.

I noticed the EURO trended farther west from yesterday. It had the energy north PR and now it takes it into DR and North of cuba.


And the UKMEt is into the eastern Gulf.

Not surprised by the UKMET having it over the eastern GOM, it continues to be biased with too much ridging in its 72-144 hr forecast.

yeah and the GFS continues to under do the ridging ..

the simple fact is that models have shifted farther west with the wave taking it across Hispaniola. that will change things.

Pretty good wave axis and good mid level vorticity.

The vorticity charts are all way off except for the 500mb vort.. the location of the 850 mb vort cannot be that far east. low level winds are out of the south in that area and its cloud free almost lol.

yeah models still initializing the vorticity/wave axis way too far east. Which would lead to the energy moving across PR vs farther west across Hispaniola or eastern Cuba.

Maybe the UKMet is just initializing the wave axis better thats why it takes into the eastern gulf.

Looking at the UKMET forecast it clearly shows more ridging on its forecast compared to the GFS and ECMWF next week.
The Euro is once again between the over ridging UKMET and the under ridging GFS.

Well that is pretty normal. lol

Wish we could see more of the UKMET parameters.

However it is still odd at least right now the GFS has the wave axis so far east.

The 12zGFS seems to try to consolidate this 50mi off of Jacksonville

One nice thing this strong tropical wave is bringing some much needed rains into the Lesser Antilles and eventual Greater Antilles.
