cieldumort explains it so well up there.. Noel is transitioning! In my opinion, it started the transition this morning as convection weakened and started to look more like a cold core storm. Folks up north will get battered from Long island, NY northwards into Novia Scotia, Canada. I will explain this again about the warnings.. the reason why tropical storm/hurricane watches and warnings were NOT issued was because Noel was and still is expected to be Extratropical (Noreaster).. If the pressure falls enough, we may get a Superstorm. I still believe Extratropical Storm Noel will get a bit closer to Cape Cod, MASS then what the NHC, however, I am in agreement with there latest path.
If you check the attachment, I made a map on "Noreaster Noel"
