Tropical Storm Alex Discussion Number  16
NWS National Hurricane Center Miami FL       AL012022
1100 AM AST Mon Jun 06 2022

Alex continues to lack deep convection anywhere near its core, 
with the majority of the heavy showers and thunderstorms displaced 
nearly 200 n mi to the northeast of the center due to the 
persistently strong shear.  Observations from an Air Force 
Hurricane Hunter aircraft indicate that the 700 mb center of 
the vortex is tilted some 30 n mi northeast of the low-level 
center, likely as a result of the shear.  Based on a blend of 
flight-level and SFMR-observed surface winds from the aircraft, the 
intensity is held at 55 kt for this advisory.  Given the 
lack of central convection and continued shear, some weakening  
and continued loss of tropical characteristics are likely today.  
However, the cyclone will probably maintain some of its intensity 
for the next day or so due to baroclinic processes.  In 36 hours or 
so, the global models depict The post-tropical low merging with an 
extratropical cyclone over the north Atlantic, so the official 
forecast shows the system as dissipated by 48 hours.

The storm continues to move rapidly toward the east-northeast, or 
around 065/25 kt.  Alex should remain embedded in the southern 
portion of the mid-latitude westerlies and continue this general 
motion for the next day or two.  The official forecast is close 
to both the simple and corrected dynamical consensus track 
forecasts, TVCN and HCCA respectively, and is also similar to the 
previous NHC prediction.


KEY MESSAGES:

1. Tropical storm conditions are expected to continue on the island 
of Bermuda for the next several hours.
