Post-Tropical Cyclone Alex Discussion Number 17
NWS National Hurricane Center Miami FL AL012022
500 PM AST Mon Jun 06 2022
Alex has not produced any deep convection near its center since last
night. It's surface circulation has also become elongated and
ill-defined. Based on these factors, Alex is now classified as
post-tropical and this will be the last advisory. The initial
intensity is set at 50 kt, assuming a little weakening has occurred
since this morning, though this is uncertain due to a lack of recent
ASCAT or surface observations.
Alex is moving quickly toward the east-northeast. Another
non-tropical low or trough is forecast to develop to the northeast
of Alex tonight. While there is quite a bit of variability in the
details, all global models forecast that Alex and the other low
will merge within the next 24 h or so, so the NHC forecast now
shows dissipation at that time. The baroclinic system that results
from that merger is expected to strengthen and could produce
hurricane-force winds over the north Atlantic by midweek. For more
information, please see forecasts from the National Weather Service
Ocean Prediction Center under AWIPS header NFDHSFAT1, WMO header
FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php.
