Post-Tropical Cyclone Epsilon Discussion Number 29
NWS National Hurricane Center Miami FL AL272020
300 AM GMT Mon Oct 26 2020

Recent satellite-derived wind data indicate that Epsilon no longer
has the structure of a tropical cyclone. The low-level circulation
is stretched out along a north-south axis, with an area of lighter
winds noted near and north of the ill-defined center. Furthermore,
infrared cloud tops have warmed over the past several hours as
convection wanes near the center. Therefore, Epsilon has been
declared a post-tropical cyclone, and this will be the last NHC
advisory for the system.

A partial 22Z ASCAT-A overpass showed at least 55-kt winds in the
southern semicircle of the cyclone, which supports keeping the
initial intensity at 60 kt. Post-tropical Epsilon is firmly embedded
in the mid-latitude westerlies, and the cyclone will continue racing
northeastward at around 35-40 kt for the next day or so. The cyclone
will remain a very powerful and dangerous storm until it is absorbed
by another large extratropical low pressure system over the
northeastern Atlantic. The global models remain in very good
agreement with this scenario, and no notable changes were made to
the official NHC forecast.
