Remnants Of Twelve Discussion Number  10
NWS National Hurricane Center Miami FL       AL122022
1100 PM AST Thu Oct 06 2022

Since the previous advisory, the center of the depression, or what 
remains of it, has become further separated by a small, highly 
sheared area of colder cloud tops. In addition, the center has 
become less defined, and low-level GOES-16 derived motion winds no 
longer indicate the system has a closed circulation. This structure 
was confirmed by a recent ASCAT-B pass, which showed the system has 
degenerated into a surface trough, albeit one that still has winds 
up to 30 kt to its northeast. Thus, this will be the last advisory 
on the system. 

The motion of the remnant low-level cloud swirl is moving just north 
of due west at 290/15 kt. This motion should continue until the 
vorticity maxima completely dissipates.
