Tornadic waterspouts in Gulf Stream

[Drz1111]

With the first strong cold fronts of autumn coming through,  wanted to pose a question to the forum:  Has there ever been any research about whether the Gulf Stream spawns tornadic storms in the Autumn?  I know from an internet dive that long distance Doppler has identified supercells with strong low-level rotation off the Space Coast of Florida using the Melbourne radar, and that's the spot where the Gulf Stream is most within range of modern radars, but further north, where the Gulf Stream is out of range, the fall brings TONS of instability, cyclonic turning with height, and plenty of shear.  It sure LOOKS like the kind of conditions that, on land, would be conducive for low-level rotation; while there's rarely the sort of cap that you'd need for big supercells, the kind of low-level shear that is modeled to occur offshore coupled with 3000+ j/kg of CAPE is normally enough at least for weak tornadoes.
