Tropical Storm Vicky Discussion Number  13
NWS National Hurricane Center Miami FL       AL212020
500 AM AST Thu Sep 17 2020
 
Strong upper-level westerly winds associated with the outflow of 
Hurricane Teddy continues to rip across the circulation of Vicky. 
These very hostile winds aloft are causing Vicky to struggle with 
maintaining deep convection, which is quite sheared and limited to 
the northeastern quadrant.  The latest satellite intensity 
estimates range from 25 to 38 kt, and the initial intensity is held 
at a possibly generous 35 kt.  Since the shear is expected to 
remain strong, Vicky is forecast to weaken to a tropical depression 
later today, a remnant low by tonight, and dissipate entirely by 
the weekend.
 
The weak storm is moving west-northwestward at 6 kt.  A turn to the
west is expected later today, followed by a west-southwest motion
after that until the cyclone dissipates in a couple of days.  The
track forecast lies near the various consensus aids.
