I see three development scenarios with this wave:

1.) it’s a low-riding Caribbean cruiser that develops in 3-5 days (00z Euro)

2.) it develops in 4-6 days and gets pulled north (Euro/EPS ensembles)

3.) it does not develop within 6 days but will track through the Caribbean and could be something to watch as it nears the west Carib/Gulf of Mexico; this could explain why the GFS and CMC aren’t showing anything as of now

Or it doesn’t develop at all and that potential STC the Euro ensembles are showing off the east coast snipes the I name.

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.

I mean I'm still trying to figure out the proper pronunciation of Georges from 22 years ago so :P Spanish gives me little trouble but French, ouch haha

Joaquin was another one that was widely mispronounced

Colors of lost purpose on the canvas of irrelevance

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

They must have had several suggestions for the new I name. Surely they could have gone with one not so awkward to pronounce?

I really REALLY just want to call him Isaiah. :lol:

I assume it's pronounced as the biblical name.

Of course we all remember Georges'

And the tsunami in Phuket Thailand (I'm sure there were a lot of newscasters saying "Uh, how do I pronounce that")

I nominate "Ichabod" for the next replacement "I" name.

Anyway, I'm following this one closely. If it does head toward Florida, looks like it will be 10ish days from now. A long ways to go, though...

The GFS doesn’t have much left of this in a few days as you can see by the simulated IR with a few pops SW of the Cape Verde islands. The real question is once it gets to the Western Atlantic later next week into next weekend, will this wave find some favorable conditions? The GFS says there won’t be enough left of this wave while the Euro insists it will develop.

Notice also from sat imagery how this wave is heavily embedded in the SAL. I expect convection to be on the downward trend the next few days:

Definitely a concerning sign to see a possible CV longtracker in late July.

The way the models are acting seems completely backwards from normal. Typically the GFS and CMC would be developing everything and the Euro and UKMET would be more conservative. Not sure what the GFS and CMC aren't seeing. Every indication is that this wave is going to be a problem. Meanwhile, the NAVGEM keeps wanting to develop Gonzalo further and send it into South Florida.

I guess that's what we get with it being 2020. Nothing is normal.

2020 has been anything but a normal year so far. So for models to not act themselves or in the usual way we’re used to seeing is not a shocker to me. These models have been throwing fits since day one, just take the East Pacific for example.

12z ICON still likes this one. 981MB on the North coast of Hispaniola in 180 hours.

This one is definitely going to have a much more favorable environment as a favorable Kelvin Wave passes. The GFS is lost in my opinion.

I'm not sure the GFS performance this year fills me with confidence that it is prepared to pull a coup over the ICON/UK/EURO alliance

The GFS has been lost for a while now. It can’t even see genesis till it’s already happening.
