The 18Z GFS model is crazy, and along the lines of the Euro. There is a possibility once the upper level low presence is gone for Sandy to re-intensify and possibly be nudged a bit west (RAP shows Bimini islands in the Bahamas... It won't actually get that far west, but it may be a bit west of where it is now, perhaps to around 150 miles offshore Florida), so tomorrow and Saturday will probably be nasty along the Florida coastline. The system is heading a bit more north northwest now than it was earlier.

GFS was the only one (until late yesterday) holding out for an out to sea scenario in the Northeast. That deep pressure drop is sure troubling, even if it doesn't verify to that degree, the impact will still be huge in the northeast.
