Tropical Depression Hermine Discussion Number   6
NWS National Hurricane Center Miami FL       AL102022
800 PM CVT Sat Sep 24 2022
 
Hermine has generally changed little during the past several hours 
and it continues to produce heavy rains across the Canary Islands. 
The cyclone remains strongly sheared with the low-level center 
exposed well to the south-southwest of the main area of deep 
convection due to strong southwesterly shear. The initial intensity 
is lowered to 30 kt, which is near the high end of the satellite 
estimates.  This makes Hermine a tropical depression. 
 
The storm is moving northward at 9 kt, and that motion is expected
to continue during the next day or two while Hermine moves in the
flow on the west side of a subtropical ridge.   After that time, a
turn toward the left is expected as the shallow system is steered by
the low-level flow.  The NHC track forecast remains near the middle
of the guidance envelope.
 
Hermine is expected to move into a region of even stronger shear,
drier air, and cooler SSTs, which should cause the storm to 
slowly weaken. The GFS and ECMWF simulated satellite images show 
that the system should lose all of its deep convection tomorrow, 
and the NHC forecast now shows the system becoming a remnant low in 
24 hours.
