Tropical Storm Leslie Discussion Number 24
NWS National Hurricane Center Miami FL AL132024
500 AM AST Tue Oct 08 2024

This morning`s satellite presentation consists of a shrinking cold
cloud top (-73C) irregular-shaped central dense overcast and curved
banding features in the south and north portion of the cyclone. A
recent METOP-B scatterometer pass revealed a somewhat distorted
asymmetric circulation located near the southeastern edge of the
convective mass. A blend of the AiDT/DPRINT/DMINT objective
estimates and a recent UW-CIMSS SATCON analysis yield an initial
intensity of 60 kt for this advisory.

A mid-tropospheric tongue of dry, stable air is penetrating Leslie`s
deteriorating convective inner core from the southwest while
mid-level southwesterly flow undercuts the diffluence aloft. The
statistical SHIPS intensity guidance shows a significant increase
in the shear magnitude by mid-period. This and the
ongoing inhibiting thermodynamic surrounding environment should
cause Leslie to lose its organized convection in 72 hrs, if not
sooner, and become a post-tropical cyclone. Further weakening is
expected throughout the period, and the official forecast indicates
that the cyclone will degenerate into a remnant low this weekend.

The initial motion is estimated to be northwestward, or 310/11 kt.
The forecast track philosophy has not changed for this advisory, and
Leslie should continue to move in the mid-level peripheral flow of
a subtropical ridge to its northeast through the end of the week.
A turn toward the north is expected around the 72 hr period as it
rounds the southwestern portion of the above mentioned ridge. Only
small adjustments were made to the NHC forecast just to agree a
little more with the skilled consensus models.
