METEOSAT imagery, IPMA radar data, and surface observations
indicate that Alpha has degenerated to a post-tropical remnant low
just a few miles to the southeast of Viseu, Portugal.  Therefore, 
this the last NHC advisory.  Surface wind data support an initial 
intensity of 25 kt.  The rapidly deteriorating small remnant low is 
expected to move generally toward the northeast at about 14 kt for 
the next 6 to 12 hours before dissipating over northern Spain by 
Saturday night.  The NHC forecast track is basically an update of 
the previous advisory and lies between the tightly clustered 
deterministic guidance.
