remarks:
192100z position near 21.3s 161.3e.
Tropical cyclone 15p (oma), located approximately 606 nm
northeast of Brisbane, Australia, has tracked south-southwestward
at 07 knots over the past six hours. Animated enhanced infrared 
satellite imagery depicts tightly-curved deep convective banding 
wrapping into a large, ragged eye. A 191705z ssmis 37ghz microwave 
image reveals a low level circulation center (LLCC) with high 
confidence. The initial intensity remains at 75 knots on the 
conservative side of Dvorak current intensity estimates ranging from 
4.5 to 5.0 (77 to 90 knots from pgtw and knes, respectively). Upper-
level analysis indicates low (5 to 15 knots) vertical wind shear 
with strong poleward outflow and weak equatorward outflow. Tc 15p is 
forecast to track southwestward through tau 36 along the western 
periphery of a subtropical ridge (str). After tau 36, the system 
should turn southward toward a break in the str associated with a 
deep shortwave trough to the south. After tau 48, there is still 
high uncertainty as the aforementioned shortwave trough shifts east 
and deepens over New Zealand. At tau 72, the system may become 
quasistationary in a more unfavorable environment of low sea surface 
temperatures, convergent westerlies and higher shear causing it to 
gradually dissipate. Therefore, there is low overall confidence 
(high uncertainty) in the jtwc forecast track and intensity after 
tau 48. Maximum significant wave height at 191800z is 25 feet. Next
warnings at 200300z, 200900z, 201500z and 202100z.//
