Post-Tropical Cyclone Paulette Discussion Number 44
NWS National Hurricane Center Miami FL AL172020
300 AM GMT Wed Sep 23 2020
Paulette has been devoid of deep convection since early Tuesday,
and the shallow convection mentioned in the previous advisory has
also waned. Therefore, Paulette has again become a post-tropical
cyclone, and this is the last NHC advisory on this system. Recent
ASCAT data showed that the system still had a small area of 35 kt
winds so the initial intensity is held at that value. The
post-tropical cyclone will be moving over waters of 22-23 degrees
Celsius and remain within an area of moderate vertical wind
shear. This should result in gradual weakening over the next
couple of days.
The post-tropical cyclone continues to move eastward or 080/10 kt.
This motion is forecast to continue through midday Wednesday, but a
reduction is forward speed is expected by Wednesday night as the
system becomes vertically shallow. The remnant low is expected to
turn southward in 24-36 hours, with a faster west-southwestward
motion anticipated later in the forecast period when it becomes
embedded within the low-level northeasterly flow.
This is the last NHC advisory on Paulette. Additional information
on this system can be found in High Seas Forecasts issued by Meteo
