PUBLIC ADVISORY #5
FORCE THIRTEEN SINGAPORE, SINGAPORE
1500 UTC WED SEP 16 2020

...VICKY WEAKENS AND LIKELY TO BECOME POST TROPICAL SOON...

SUMMARY OF 1500 UTC...INFORMATION
-----------------------------------
LOCATION...NEAR 21.5 N 34.7 W...
MAXIMUM SUSTAINED WINDS...40MPH...65KM/H
MINIMUM CENTRAL PRESSURE...1008MB

WATCHES AND WARNINGS
-----------------------------------
NO WARNINGS IN EFFECT.
DISCUSSION
-----------------------------------
Hostile vertical shear of 50 to 60 kt has finally taken a toll on 
Vicky. A 1227 UTC ASCAT-B overpass showed peak winds of 35 kt north 
of the center, and that is the basis for the advisory intensity. The 
strong shear is expected to continue while Vicky moves over marginal 
26-27C SSTs, so additional weakening is forecast. Vicky should 
become a tropical depression in around 24 hours before weakening to 
a remnant low in about 2 days, with dissipation expected by day 3. 
However, the timing of when organized deep convection will finally 
cease is difficult to determine, so its is possible Vicky could 
weaken faster than indicated here or hang on a bit longer.
