POST-TROPICAL CYCLONE MARTIN DISCUSSION NUMBER 10  
NWS NATIONAL HURRICANE CENTER MIAMI FL AL162022  
900 PM GMT THU NOV 03 2022  
 
ASCAT-C DATA THAT WAS NOT AVAILABLE UNTIL AFTER THE ISSUANCE OF THE  
LAST ADVISORY, BUT WAS VALID AT 1317 UTC, SHOWED THAT MARTIN LIKELY  
BECAME FRONTAL EARLIER TODAY AND THE SYSTEM NO LONGER HAS A  
WELL-DEFINED CIRCULATION. IN ADDITION, BOTH TAFB AND SAB EVALUATED  
THE SYSTEM AS EXTRATROPICAL AT 1800 UTC. THEREFORE, MARTIN IS NOW  
CLASSIFIED AS POST-TROPICAL AND THIS WILL BE THE LAST NHC ADVISORY.  
 
WHILE MARTIN DOES NOT CURRENTLY APPEAR TO HAVE A WELL-DEFINED  
CENTER, THE POWERFUL POST-TROPICAL CYCLONE IS EXPECTED TO REDEVELOP  
A WELL-DEFINED CENTER AS IT OCCLUDES OVER THE NEXT 12 TO 24 H.  
MARTIN IS MOVING AT A REMARKABLE CLIP OF 50 KT, BUT SHOULD BEGIN TO  
SLOW DOWN SOON AND TURN NORTH-NORTHWESTWARD DURING THE NEXT FEW  
HOURS. AFTER THAT, THE CYCLONE IS FORECAST TO MOVE RELATIVELY SLOWLY  
ON FRIDAY BEFORE PICKING UP SPEED TOWARD THE EAST-SOUTHEAST OR EAST  
THROUGH THE EARLY WEEKEND. MARTIN'S MAXIMUM WINDS ARE STILL FORECAST  
TO SLOWLY DECREASE OVER THE NEXT FEW DAYS, HOWEVER THE COMBINATION  
OF MARTIN AND OTHER NON-TROPICAL LOW PRESSURE SYSTEMS ARE STILL  
EXPECTED TO PRODUCE HAZARDOUS WIND AND SEAS OVER A VERY WIDE AREA OF  
THE NORTH ATLANTIC FOR THE NEXT COUPLE OF DAYS.
