Post-Tropical Cyclone Debby Discussion Number  10
NWS National Hurricane Center Miami FL       AL042018
500 PM AST Thu Aug 09 2018

Debby has become post-tropical. The circulation of the cyclone has
become ill defined, and it is no longer producing enough organized
deep convection to be classified as a tropical cyclone.  Therefore,
Debby has become post-tropical, and this is the last advisory. The
cyclone is accelerating northeastward ahead of a shortwave trough,
and this should continue for the next few hours until Debby opens up
into a trough of low pressure and merges with a larger frontal
boundary later tonight.

Debby is likely still producing gale-force winds to the southeast
of its center, however all of the guidance indicates that these
winds will gradually decrease through early tomorrow.  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 available on the Web
at https://ocean.weather.gov/shtml/NFDHSFAT1.shtml.
