NHC discussion of the intensity:
Dorian could maintain this intensity for about 12 hours or so,
but guidance is showing shear increasing, and that should result
in gradual weakening. The intensity forecast is basically the same
as the previous advisory, keeping Dorian at the border of category 2
or 3 intensity as it moves near the southeast coast of the United
States. This forecast is consistent with the intensity models, which
unanimously gradually weaken the cyclone.
