So, as of hour 156, the 12Z GFS is about 300 miles NE of the 0Z Euro hour 168 position! Just a little bit of disagreement. :lol:

Great point. The Euro is so much slower. Maybe that is why it had a WNW turn at the end of its run last night because it is slower? Maybe faster means more NE???

We may be seeing why the MU is the MU with this run. That turn looks incredibly bogus

One has to doubt the GFS depiction of a Cat 5 Hurricane in the East-Central Caribbean. This is more than likely the reason for the due north movement as it is being steered at a different level. Could happen, but that raises a red flag...

This might actually be realistic...History has shown us that sometimes these large gyres take some time to consolidate and get their act together. Couple that with the possibility of restricted inflow off of SA and you have the recipe for slow but steady strengthening.

And if it does take forever to get strong and track similarly to the 12Z UKMET (almost to 76W moving NW), that's very likely trouble for the CONUS, especially FL.

Models seem to be trending North and east. Bad news for DR and Haiti but better for the CONUS. Still early in the game. As for a Cat 5 if conditions are what I am seeing it is very possible.

The GFS/GEFS have but not the 0Z Euro/EPS nor the 12Z UKMET.

It wouldn't be the first time that the GFS has overcooked something. I agree that is why we are seeing it get pulled north so abruptly. Based on how things have developed this year as well as in recent years I think a slow and steady strengthening is more likely. Along with the fact that it is a very large gyre so it will take some time to consolidate.

Yes, the 12Z UKMET is a whopping 350 miles WSW of the 0Z UKMET!

At that timeframe and at that approach from the south it is WAY to early to feel comfortable here in Florida or the rest of the CONUS for that matter. The evolution of the shortwave is going to be HUGE!!!
