That sure looks like a favorable environment to me. Look at the upper-high north of Hispaniola. The GFS probably did not show redevelopment this run since it has the invest interacting with Hispaniola and Cuba:

I wouldn't be so sure about that yet as this could still miss the islands to the north

Yeah, you never know what's going to happen once a system nears the Bahamas. Conditions may be lackluster now, but they could end up improving in a few days. Keeping a watchful eye on it.

Just coming to post that. Fast forward 24hrs later and beyond and shear in Bahamas, South Florida, and eastern gulf is pretty unfavorable. If the GFS is correct, big if, that is why it isn't showing anything.

Shear forecasts change every run, anything entering the Bahamas with a vigorous circulation can be lethal.

The GFS shear forecast in the Bahamas looks fairly favorable to me...I'm not sure what GFS forecast your looking at? The GFS plows 92L into Hispaniola and that's why development is not shown in the Bahamas.

I have no idea why the GFS doesn't redevelop this again with the more favorable conditions, could it be a new bias in the GFS

I don't buy this run of the GFS so far. Shows a depression at the beginning of the run and then shows an open wave by hour 78. Will conditions really be that unfavorable?

Looks to me like the wind shear really starts to let up at hour 108.. We're still at hour 114, so lets see.

And now at hour 120, looks like the GFS is still saying nothing to see here but a weak TW about to get buried into the north-eastern coast of Cuba.

Yeah, this isn't Hispaniola interaction that's causing the weakening. It looks like it's pulling down another rogue ull and moving westward in tandem with 92L

I don't get it either...could be dry air...looking at the model soundings the RH is fairly low but shear doesn't look to be a big problem.
