Maximum sustained winds have decreased to near 30 mph (45 km/h)
with higher gusts. The remnant low is expected to dissipate by
Saturday night.
The estimated minimum central pressure is 1005 mb (29.68 inches).

Post-Tropical Cyclone Alpha Discussion Number 3
NWS National Hurricane Center Miami FL AL242020
300 AM GMT Sat Sep 19 2020
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.
Additional information on the hazards from this system can be found
in products from the Portuguese Institute for Sea and Atmosphere at
