Tropical Storm Leslie Discussion Number 39
NWS National Hurricane Center Miami FL AL132024
1100 PM AST Fri Oct 11 2024

Convection associated with Leslie has been increasing during the
past several hours as the cyclone moves into an area of temporarily
decreased shear. A recent ASCAT overpass showed winds of 40-45 kt in
the southeastern quadrant, and based on these data the initial
intensity is held at 45 kt. The scatterometer data also suggest
that the circulation is becoming somewhat distorted due to the rapid
northeastward motion.

The initial motion is now 035/19 kt. The cyclone is accelerating
northeastward as it moves into the mid-latitude southwesterly flow
to the east of a deep-layer trough over the northwestern Atlantic.
This general motion should continue for 24 h or so. After that,
Leslie or its remnants should turn eastward and east-southeastward
on the southwestern side of another deep-layer trough located over
the northeastern Atlantic, with this motion continuing until the
system dissipates. There are no significant changes in the track
guidance since the previous advisory, and the new forecast track is
similar to the previous track.

Shear over Leslie should remain relatively low for the next 12-18
h, allowing the current convection to continue and the system to
maintain tropical cyclone status during that time. The global
models have come into good agreement that Leslie will merge with a
frontal system to become extratropical between 24-36 h, and thus the
intensity forecast status has been adjusted accordingly. The
extratropical cyclone should subsequently weaken and be absorbed
into the larger system over the eastern Atlantic by 96 h. It should
be noted that while the models show a closed low pressure area
through 72 h, the circulation could degenerate into an open trough
before then due to the fast forward speed.
