EPSILON BECOMES A POWERFUL POST-TROPICAL CYCLONE OVER THE

NORTH ATLANTIC

ALERTS
HAZARDS
SUMMARY
DISCUSSION

There are no coastal watches or warnings in effect.


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 lifethreatening surf and rip current conditions. Please consult products from your local weather office.


At 300 AM GMT (0300 UTC), the center of PostTropical Cyclone Epsilon was located near latitude 48.6 North, longitude 38.8 West. The posttropical 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 posttropical cyclone is absorbed by a large extratropical low pressure system on Monday night or early Tuesday.

Tropicalstormforce winds extend outward up to 450 miles (720 km) from the center.

The estimated minimum central pressure is 968 mb (28.59 inches).


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. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php
