Tropical Storm Melissa Discussion Number 4
NWS National Hurricane Center Miami FL AL132025
500 AM EDT Wed Oct 22 2025
Data from an Air Force Reserve Hurricane Hunter aircraft has been
extremely useful in showing that the center of Melissa has
re-formed to the northeast of the previous center. Earlier
scatterometer data had already shown an elongated circulation, and
the very deep convection combined with the moderate westerly shear
has caused the re-formation. The initial intensity is kept at 45
kt, a compromise between somewhat lower aircraft winds but also
lower central pressure, now at 1000 mb.
The initial motion is estimated, with low confidence, to be 295/6.
Melissa is forecast to move very slowly to the northwest and
north-northwest during the next few days into a weakness by an
approaching mid-latitude trough. There continues to be a very
large uncertainty on whether the storm would turn more into the
weakness and threaten Haiti or Cuba, or whether it would turn
more westward to the south of Jamaica as a ridge rebuilds over the
Bahamas, with reliable models in either camp. This appears to be
somewhat tied to the storm's structure, with the less vertically
coherent model solutions generally ending up on the western side of
the track envelope this weekend, and stronger initial storm
representations on the northeastern side. With such a distinct
track bifurcation noted in the guidance (excluding the consensus
aids) and dependence on structure, this should be considered an
extremely uncertain forecast, and significant changes could be
required. The model trends have been favoring the more westward
solutions recently, and the official forecast is nudged in that
direction at long range.
