Remnants Of Josephine Discussion Number  21
NWS National Hurricane Center Miami FL       AL112020
500 PM AST Sun Aug 16 2020
 
The low-level swirl seen in visible satellite imagery has become 
less defined this afternoon, and ASCAT surface wind data that 
arrived shortly after the release of the previous advisory indicated 
that Josephine had degenerated into a trough of low pressure.  As a 
result, this will be the final NHC advisory on this system.  The 
ASCAT revealed a small area of 30-kt winds along the northeast side 
of the trough axis, and that will be the initial wind speed for 
this advisory.  The remnants are forecast to continue encountering 
a hostile upper-level wind environment over the next couple of days 
and re-generation of the system is not expected during that time. 
The strong upper-level winds are forecast to decrease later in the 
week, but it appears that there will not be much left of the system 
to take advantage of those conditions.
 
The remnants are moving west-northwestward at 10 kt, and should
turn northwestward and northward over the next couple of days as a
low- to mid-level trough moves near the southeastern U.S. coast.
 
This is the last NHC advisory on this system.  Future information
can be found in High Seas Forecasts issued by the National Weather
Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and
