I do believe the NHC wrote off Gabrielle a bit prematurely, based upon current IR/AVN imagery. It's no threat to land anymore, but is potentially a threat to north Atlantic shipping interests (the Canadian maritimes, and even the mainland Canadian Atlantic coast). The satellite signature looks to me like a decent TROPICAL storm, not an extratropical low, even as far north as the low now is.

91L is also looking like it should now be classified as a TD, with Humberto not far off.
