Tropical Storm Melissa Discussion Number 1
NWS National Hurricane Center Miami FL AL132025
1100 AM EDT Tue Oct 21 2025

Satellite images, regional Caribbean radar data, and surface
observations indicate that invest 98L has developed a well-defined
center and organized deep convection to be designated a tropical
cyclone. A ship report that recently passed near the center of the
system reported a minimum pressure of about 1003 mb. Satellite
imagery shows the system is asymmetric, with the low-level center
near the western edge of the central dense overcast. The initial
intensity is set at 45 kt, based on a blend of the latest satellite
intensity estimates, marking the formation of Tropical Storm
Melissa. An Air Force Hurricane Hunter aircraft is scheduled to
investigate the system this afternoon, and their data should provide
a better assessment of Melissa's strength and structure.

The system was moving very quickly westward over the past several
days, but it has slowed down significantly this morning, which has
likely helped Melissa form. The initial motion is estimated to be
280/12 kt. Melissa should continue to slow down and gradually turn
to the northwest and then north during the next couple of days
toward a weakness in the subtropical ridge. This motion will likely
take the storm very near the southwestern tip of Haiti and Jamaica
by Thursday. After that time, the guidance diverges significantly
with some models like the GFS and HWRF showing a motion to the
northeast into the weakness, while the other solutions show a stall
or a westward drift on the south side of a building ridge. An
examination of the GFS, ECMWF, and Google DeepMind ensemble suites
suggest that the majority of the members show Melissa not moving
into the weakness and remaining in the Caribbean Sea throughout the
week and into the weekend. The NHC official track forecast lies
between the Google DeepMind ensemble mean track and the correct
consensus aid, HCCA.

Tropical Storm Melissa Discussion Number 2
NWS National Hurricane Center Miami FL AL132025
500 PM EDT Tue Oct 21 2025

Satellite data indicate that Melissa is struggling in strong shear,
which has been the theme for many systems over the deep tropics this
year. The low-level center of the storm is exposed to the west of
the main area of thunderstorms. Air Force Hurricane Hunters have
been investigating the system this afternoon and found that the
minimum pressure is around 1003 mb. Based on their observations,
ASCAT passes, and Dvorak estimates, the initial intensity is held at
45 kt. Melissa's wind field is also quite asymmetric, with most of
the tropical-storm-force winds occurring on the system's east side.
Some of the outermost northern bands are approaching Hispaniola, and
these heavy rains are expected to spread across that island during
the next couple of days.

Melissa is a little south of the previous track and it continues to
move westward at about 13 kt. There has been no change to the track
forecast scenario, which remains complicated. Over the next couple
of days, there is fair confidence that Melissa should slow down and
gradually turn to the northwest or north and approach Haiti and
Jamaica late this week. The motion after that appears to be linked
to how strong and vertically aligned the system gets, and
that is when the models diverge. If Melissa organizes like the GFS
predicts, it could turn northeastward into the weakness in the
ridge and move over Hispaniola. Conversely, if Melissa remains
sheared and lopsided, it will likely stall and eventually drift
westward as a ridge builds north of it. Given the expected
continued shear, the NHC track forecast leans toward the latter
scenario. This prediction is a little left of the previous forecast
and remains a blend of the latest Google DeepMind ensemble mean,
the corrected consensus aid HCCA, and simple consensus TVCA.
