The local news here in Orlando keep saying a CAT 3 with “possibility” of reaching a 4. I believe it is because of the warm gulf stream water it will cross and it will already be a strong CAT 3 at 125 mph.
I agree - even the forecasters say 70% chance of Cat 3. And yes, going right over the gulf stream. The gulf stream is an amazing thing - it even creates its own localized weather patterns. It's also why some of the waters off the eastern seaboard of the US that are in or adjacent to the gulf stream are known as the ship's graveyard.
