Post-Tropical Cyclone Epsilon Forecast Discussion Number 29
2020-10-26 03:36:14| National Hurricane Center (Atlantic)
Issued at 300 AM GMT Mon Oct 26 2020 000 WTNT42 KNHC 260236 TCDAT2 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.
