It is a really interesting how this evolves. As Humberto moves around the Atlantic ridge it "tugs" on Imelda by causing a path of least resistance. But Humberto is far enough along in the recurve that it accelerates north and allows the ridge to build over Imelda. How exactly this plays out determines how far offshore Imelda gets, which in turn affects how close it can get to the US coast when it gets picked up by the next trough. The 6z GFS pulls it pretty far out to sea, so any landfall is in the Canadian maritimes or not at all. The 6z Euro leaves it off the Carolina coast through 144, which is markedly different form the 0z run. The 0z GEM eventually takes it into New England!
Is there a win for us? Very unlikely. We'd need for it to be left behind and just churn over the Gulf Stream and then have a trough dig far enough to bring it in to us. I'd be more optimistic about this in later October, but it seems like a pipe dream here.
