This new NHC track
is close to the corrected model consensus and between the quicker
ECMWF and slower GFS models. It should be emphasized that this
track remains uncertain, with a typical spread in the steering
features leading to big speed and track differences down the line,
not to mention the oblique angle of approach to Florida.
In a few
days, more of the guidance is showing Ian interacting with a
shortwave trough over the southeastern United States, causing the
system to move back over the northwestern Atlantic in the longer
range, before turning northwestward back over land. The day 3-5
track forecast is also shifted eastward, although significant
re-strengthening is not expected at long range.
