Tropical Cyclone 16S (Hina) Weakening
Tropical Cyclone 16s (Hina), located approximately 770 nm south-southeast of Diego Garcia, has tracked westward at 8 knots over the past 6 hours. Maximum significant wave height is 19 feet.
The system has weakened dramatically under the influence of increased vertical wind shear ahead of a longwave trough and restricted equatorward outflow.
This weakening trend is reflected in satellite intensity estimates from PGTW, KNEW, and FMEE, which range from 25 to 35 knots.
Position confidence is good and is based upon a 232325z 37h TRMM image depicting a fully exposed low level circulation center (LLCC).
As the system has weakened, the steering influence of the storm has shifted to the low-to mid-level ridge southeast of the cyclone, resulting in a predominantly westward motion over the past 06 hours.
The storm will continue in a generally westward to southwestward direction and ultimately dissipate as a significant tropical cyclone within the next 12 hours.
This is the final warning on this system by the Joint Typhoon Warning Center, although the system will be closely monitored for signs of regeneration.
