Hurricane Epsilon Discussion Number  26
NWS National Hurricane Center Miami FL       AL272020
500 AM AST Sun Oct 25 2020

Although the cloud pattern of Epsilon is beginning to expand over
the northwestern portion of the circulation as the hurricane begins
its extratropical transition, the storm continues to produce
inner-core convection.  Recent shortwave infrared satellite imagery
suggest that there is some northeast-to-southwest tilt between the
mid- and low-level centers. Since there has been little overall
change in the inner-core structure since the previous advisory, the
initial intensity is held at 65 kt in agreement with the earlier
ASCAT data.

Epsilon is moving north of the north wall of the Gulf Stream and
will be over much colder SSTs later this morning.  This, along with
an approaching baroclinic zone, should cause Epsilon to quickly lose
its tropical characteristics and become an extratropical low by
later today. The post-tropical cyclone is expected to remain a large
and powerful cyclone over the north Atlantic during the next day or
so.  The global models indicate that the post-tropical cyclone will
be absorbed by a large extratropical low over the north Atlantic
within 48 hours.

The hurricane continues to accelerate northeastward, with an initial
motion estimate of 050/26 kt. A continued northeastward acceleration
is expected through tonight, and rather faster northeastward motion
is forecast until the post-tropical cyclone is absorbed by the
larger extratropical low Monday night.  The track guidance remains
tightly clustered and the new NHC forecast track is essentially an
update of the previous advisory.
