Post-Tropical Cyclone Eleven Discussion Number   6

The structure of the system this afternoon has continued to go 
downhill. The circulation fidelity has become increasingly diffuse 
and stretched out in a north-to-south fashion. What little deep 
convection remains is displaced about 100 n mi to the 
north-northeast of the center and also lacks sufficient organization 
to be considered a tropical cyclone. Therefore, this is the final 
advisory and the system is now considered to be a post-tropical 
remnant low, albeit one that is likely to open up into a surface 
trough at any time. 

In general the poorly-defined center still appears to be mostly on 
track, moving to the northwest at 320/12 kt. This general motion is 
expected to continue until the elongated circulation completely 
degenerates into a surface trough over the central Atlantic basin. 
A 12 hour point is mainly provided for continuity purposes, which 
lies along the fairly tightly clustered consensus aids.
