Late in the period, the
guidance indicates the storm will begin to recurve toward Florida.
As mentioned before, the track models are in general agreement with
this scenario, however there is a large amount of cross-track
spread at 72 hours and beyond. In fact, the east-west spread in
the guidance at 96 hours is about 180 n mi, with the CTCI and ECMWF
along the eastern side of the envelope, and the GFS, HWRF, and GFS
ensemble mean along the western side. The overall guidance
envelope has shifted slightly westward this cycle, and the NHC
track has been nudged in that direction and lies just east of the
various consensus aids. Given the spread in the guidance, and
the still shifting dynamical models, additional adjustments to the
track forecast may be needed in subsequent advisories. Users are
reminded that the long-term average NHC 4- and 5-day track errors
are around 150 and 200 n mi, respectively.
