Following the Florida landfall, the NHC track takes Debby on a curving northeast path that appears to be going out to sea. Considering a climatologically favorable track is for Debby to curve up the coast and possibly hit New England (like many winter storms), that would be a favored option. However, the forecast models are finally in agreement that Debby should be kicked out to sea from the get-go after leaving Florida.
This seems likely, considering a cold front with trailing high pressure will be pushing south, resulting in a squeeze of Debby eastward. At that point, Debby will be too far away from the coast to hug it.
