Tropical Storm Epsilon Discussion Number   4
NWS National Hurricane Center Miami FL       AL272020
1100 PM AST Mon Oct 19 2020
 
Water vapor imagery indicates that Epsilon has been interacting with 
a shear line/dissipating cold front from the north and with a 
negatively tilted upper-level trough from the south. Furthermore, a 
pronounced dry slot has developed in the eastern semicircle, which 
has severed the convective band that had been wrapping about 
three-fourths of the way around the circulation. Overall, the cloud 
pattern more closely resembles that of an occluded extratropical 
low, with a small inner-core tropical feature. A 20/0025Z ASCAT-A 
pass indicated a small fetch of mostly straight-flow 40-kt winds 
located 60-90 nmi northeast of the well-defined surface center. 
Given the distance from the low-level center and lack of any 
significant curvature to those winds, undersampling is probably not 
occurring. Therefore, the initial intensity is being held at 40 kt 
for this advisory, which is consistent with satellite 
classifications of T2.5/35 kt from TAFB, SAB, and UW-CIMSS ADT, and 
a 19/2202Z SATCON estimate of 42 kt. Epsilon is a large cyclone with 
gale-force or tropical-storm-force winds extending outward more than 
250 nmi in the northern semicircle.
 
The initial motion estimate is 360/02 kt. No significant changes 
were made to the previous track forecast or reasoning. Epsilon is 
expected to meander within weak steering currents well to the 
southeast of Bermuda for the next 12 h or so. By late Tuesday, a 
ridge is forecast to build to the north and east of the cyclone, 
forcing Epsilon generally toward the northwest through Friday. As an 
upper-level trough and associated frontal system approach the 
cyclone, Epsilon is expected to turn sharply northeastward between 
the trough and the ridge by late Friday, and accelerate 
northeastward thereafter over over the north Atlantic. The latest 
NHC model guidance is coming into better agreement, with a tight 
clustering of he various consensus models lying essentially along 
the previous advisory track. On the forecast track, Epsilon should 
make its closest approach to Bermuda on Friday.

Epsilon is forecast to remain over sea-surface temperatures (SST) of 
at least 27C the next 36 h or so and, when coupled with 200-mb 
temperatures of -55C, sufficient instability will exist to continue 
to allow for deep convection to be generated both in the inner- and 
outer-core regions of the cyclone. Thus, gradual strengthening is 
forecast during that time. However, by 48 h and continuing through 
72 h, SSTs cool to near 26.5C and the depth of the relatively warm 
water becomes quite shallow, as indciated by upper-ocean heat 
content values dropping to near zero by 72 h. The large and 
expansive wind field should result in cold upwelling both ahead of 
and beneath the inner-core wind field, which is likely to temper the 
intensification process. This may be reflected in the past couple of 
HRWF runs which no longer make Epsilon a hurricane by the time the 
cyclone approaches Bermuda on Friday. For now, the intensity 
forecast has only been lowered slightly since there may be some 
baroclinic interaction with an approaching upper-level trough that 
could offset the cooler waters. Epsilon could be undergoing 
extratropical transition by the 120-h forecast period, but for now 
the system will be shown as still being tropical since it will be 
located over marginal SSTs near 26C at that time.

Key Message:
 
1. Epsilon is forecast to be at or near hurricane strength when
it approaches Bermuda late this week.  While it is too soon to
determine the exact details of Epsilon's track and intensity near
the island, there is a risk of direct impacts from wind, rainfall,
and storm surge on Bermuda, and interests there should closely
monitor the progress of Epsilon.

WATCHES AND WARNINGS
--------------------
There are no coastal watches or warning in effect.
 
Interests in Bermuda should monitor the progress of Epsilon.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Tropical Storm Epsilon was 
located near latitude 25.3 North, longitude 55.3 West.  Epsilon is 
drifting toward the north near 2 mph (4 km/h), and this general 
motion should continue tonight and early Tuesday.  A northwestward 
motion is expected to begin by Tuesday afternoon and continue 
through midweek.  On the forecast track, Epsilon is forecast to 
approach Bermuda on Thursday.

Maximum sustained winds remain near 45 mph (75 km/h) with higher 
gusts.  Gradual strengthening is expected during the next couple of 
days, and Epsilon is forecast to be at or near hurricane strength by
Wednesday night.
 
Tropical-storm-force winds extend outward up to 275 miles (445 km)
from the center.
 
The estimated minimum central pressure is 998 mb (29.47 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF:  Large swells generated by Epsilon are expected to affect
Bermuda for the next several days.  These swells are likely to
cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.
 
 
NEXT ADVISORY
-------------
Next complete advisory at 500 AM AST.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Mon Oct 19 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Storm Epsilon, located over the central Atlantic several
hundred miles southeast of Bermuda.

A trough of low pressure extends southeastward across the
northwestern Caribbean Sea to a broad low pressure system located
over the southwestern Caribbean Sea. Associated shower and
thunderstorm activity remains disorganized and is primarily located
over the southwestern Caribbean Sea. This large disturbance is
expected to consolidate over the northwestern Caribbean Sea during
the next day or so before move drifting westward toward the Yucatan
peninsula by Wednesday. Regardless of development, the system could
bring locally heavy rainfall to portions of central and western
Cuba, Jamaica, the Cayman Islands, and the Yucatan peninsula through
midweek.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

&&
Public Advisories on Tropical Storm Epsilon are issued under WMO
header WTNT32 KNHC and under AWIPS header MIATCPAT2.
