Tropical Depression Twelve Discussion Number 4
NWS National Hurricane Center Miami FL AL122022
1100 AM AST Wed Oct 05 2022

The depression continues to lose organization. Visible satellite
imagery reveals an exposed low-level swirl displaced nearly 90 n mi
west of its associated deep convection due to strong
west-southwesterly vertical wind shear. The initial advisory
intensity of 30 kt may be a little generous, and is based off a
blend of the latest Dvorak intensity estimates. The shear affecting
the depression is forecast to increase further, while the system
ingests dry air to its west. This should disrupt significant deep
convection from reforming near its low-level center. In fact,
simulated satellite imagery from the GFS and ECMWF suggest that the
deep convection will not return and the system should become a
remnant low within the next 24 h. The latest NHC intensity forecast
is unchanged from the previous one. However, the forecast now
indicates that the depression will become a remnant low by 24 h.

The 12 h motion of the depression is about 295/8 kt. However, the
low-level center has been moving nearly westward over the past
several hours. Most of the model guidance indicates a
west-northwestward track to the south-southwest of a mid-level ridge
over the next couple days until dissipation. The NHC track forecast
has been adjusted to the left of the previous one and is on the
left side of the guidance envelope, as it is assumed that the
shallow low-level circulation is going to be steered more by the
low-level flow than the models indicate.
