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.  
 
ADDITIONAL INFORMATION ON THIS SYSTEM CAN BE FOUND IN HIGH SEAS
