It's going to completely miss Haiti to the east at this point. If there will be any land interaction, it'll be Puerto Rico.In my humble opinion though, I think the bend back west will occur slightly sooner after it passes Haiti than current thinking assuming it holds together and South Florida is the main target. I am very surprised more of the models don't dissipate this while near Haiti. Besides the fact it will spend time over land (albeit the lesser mountainous parts of Haiti and for only about 12 hours), I have had a hard time envisioning the shear not degenerating it into an open wave.
As far as shear is concerned, it depends on the positioning of the ULL that will be moving WSW over the Florida Straits and Cuba.
