 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
