CHANGES WITH THIS ADVISORY:
None
SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
A Tropical Storm Warning is in effect for...
* Bermuda
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.
For storm information specific to your area, please monitor
products issued by your national meteorological service.
DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Hurricane Epsilon was
located near latitude 31.9 North, longitude 61.4 West. Epsilon is
moving toward the north-northwest near 9 mph (15 km/h). A general
northward motion is expected through early Saturday with a faster
motion toward the northeast later that day. The center of Epsilon
will pass well east of Bermuda tonight.
Maximum sustained winds have decreased to near 85 mph (140 km/h)
with higher gusts. Some fluctuations in strength are expected for
the next couple of days before gradual weakening starts on Sunday.
Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 240 miles
(390 km).
The estimated minimum central pressure is 968 mb (28.59 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected intermittently on
Bermuda through this evening.
SURF: Large swells generated by Epsilon will affect Bermuda, the
Bahamas, the Greater Antilles, the Leeward Islands, the east coast
of the United States, and Atlantic Canada during the next few days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Hurricane Epsilon Discussion Number 16
NWS National Hurricane Center Miami FL AL272020
500 PM AST Thu Oct 22 2020
Satellite images indicate that the eye of Epsilon has lost
definition over the past several hours. While satellite intensity
estimates haven't changed much yet, they were generally higher than
the earlier reconnaissance data. The initial wind speed is set to
75 kt, on the lower side of the satellite estimates after placing
more weight on the aircraft data.
Epsilon is moving faster to the north-northwest this afternoon, at
roughly 8 kt. The hurricane should turn northward overnight and
continue on that heading for a day or two while it moves through a
break in the central Atlantic ridge. Epsilon is likely to move
considerably faster to the northeast over the weekend as it get
caught in the mid-latitude flow. The only significant adjustment
to this forecast is a small northward shift in a couple of days.
The new NHC track is still south of the model consensus over the
weekend and beyond, placing more emphasis on the global models than
the regional hurricane guidance. After 72 hours, the cyclone is
forecast to merge with a much larger extratropical cyclone over the
far north Atlantic.
The small core that Epsilon has maintained for the past couple of
days seems to be degrading, and perhaps it is forming a larger
secondary wind maximum based on AMSR microwave data. Otherwise, a
trough interaction and a small warm eddy near the Gulf Stream could
lead to a slight recovery in Epsilon's strength tomorrow or
Saturday. Either way, the global models make this hurricane's
wind field quite a bit larger (especially the 50- and 64-kt winds),
and that's reflected in the latest wind radii forecast. The new
NHC wind speed prediction is about the same as the previous one,
adjusted slightly for a lower initial wind speed.
Key Messages:
1. Tropical storm conditions are expected intermittently on Bermuda
through this evening, when Epsilon is forecast to make its closest
approach east of the island. A Tropical Storm Warning is in effect
for Bermuda.
2. Dangerous and potentially life-threatening surf and rip currents
are expected along the coasts of Bermuda, the Bahamas, the Greater
Antilles, the Leeward Islands, the east coast of the United States,
and Atlantic Canada during the next couple of days.
