Tropical Depression Twelve Discussion Number 1
NWS National Hurricane Center Miami FL AL122022
500 PM AST Tue Oct 04 2022

A fairly concentrated area of deep convection has persisted near an
area of low pressure that NHC has monitoring a few hundred miles
west of the Cabo Verde Islands, and Dvorak classifications from TAFB
and SAB are now a consensus T2.0/30 kt. It hadn`t been clear
previously how well-defined the system was, but an ASCAT-C
scatterometer pass from this morning suggested that a small
circulation, with a well-defined center, had formed within the
broader trough located over the eastern Atlantic. Therefore,
advisories are being initiated on Tropical Depression Twelve with
maximum sustained winds of 30 kt.

The depression is located along the southwestern periphery of a
mid-level high centered over northwestern Africa, and to the south
of a prominent mid- to upper-level low. This pattern should steer
the cyclone northwestward or north-northwestward during the next
couple of days. The HWRF model is somewhat of an outlier to the
northeast and is therefore pulling the track model consensus aids in
that direction. The NHC track is near or to the west of the
consensus aids, more closely following the GFS and ECWMF global

Deep-layer southwesterly shear is already beginning to increase over
the depression, and is likely to reach values of 30 to 35 kt in the
next 36 to 48 hours. The system has some potential to strengthen
slightly and reach tropical storm strength tonight or on Wednesday,
but for the most part the cyclone is expected to be short-lived.
Global models show the system opening up into a trough in a few
days, and the NHC forecast shows dissipation by 60 hours, which
could be a little generous.
