300 AM GMT Mon Oct 26 2020
...EPSILON BECOMES A POWERFUL POST-TROPICAL CYCLONE OVER THE
NORTH ATLANTIC...
...THIS WILL BE THE LAST NHC ADVISORY ON EPSILON...
SUMMARY OF 300 AM GMT...0300 UTC...INFORMATION
----------------------------------------------
LOCATION...48.6N 38.8W
ABOUT 675 MI...1090 KM ENE OF CAPE RACE NEWFOUNDLAND
MAXIMUM SUSTAINED WINDS...70 MPH...110 KM/H
PRESENT MOVEMENT...NE OR 55 DEGREES AT 46 MPH...74 KM/H
MINIMUM CENTRAL PRESSURE...968 MB...28.59 INCHES
WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.
DISCUSSION AND OUTLOOK
----------------------
At 300 AM GMT (0300 UTC), the center of Post-Tropical Cyclone
Epsilon was located near latitude 48.6 North, longitude 38.8 West.
The post-tropical cyclone is moving toward the northeast near 46 mph
(74 km/h), and this general motion is expected to continue through
Monday night.
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Little change in strength is forecast during the next day
or so before the post-tropical cyclone is absorbed by a large
extratropical low pressure system on Monday night or early Tuesday.
Tropical-storm-force winds extend outward up to 450 miles (720 km)
from the center.
The estimated minimum central pressure is 968 mb (28.59 inches).
HAZARDS AFFECTING LAND
----------------------
SURF: Large swells generated by Epsilon will affect Bermuda, the
Bahamas, the Greater Antilles, the Leeward Islands, portions of the
east coast of the United States, and Atlantic Canada through Monday.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.
NEXT ADVISORY

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.

Forecasts issued by the National Weather Service, under AWIPS
