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.
