Tropical Disturbance Summary For area Equator to 25S, 160E to 120W
ISSUED FROM RSMC NADI Dec 162342 UTC.

TROPICAL DISTURBANCE 02F [1003HPA] WAS ANALYSED NEAR 14.1S 178.0W AT
162100UTC. TD02F MOVING EAST AT ABOUT 10 KNOTS. POSITION POOR BASED
ON HIMAWARI-8 SATELLITE VIS AND IR IMAGERY AND PERIPHERAL SURFACE
OBSERVATIONS.

CONVECTION REMAINS PERSISTENT OVER SUPPOSED LLCC IN THE PAST 12 TO 24
HOURS. ORGANISATION REMAINS POOR. THE SYSTEM LIES UNDER AN UPPER
RIDGE WITH GOOD UPPER DIVERGENCE AND LOW WIND SHEAR. CYCLONIC
CIRCULATIONS EXTENDS UPTO 850HPA. SST AROUND 31 DEGREES CELSIUS.

GLOBAL MODELS HAVE PICKED UP THE SYSTEM AND INITIALLY MOVE IT
EASTWARDS WITH SLIGHT INTENSIFICATION BEFORE MOVING IT SOUTHEAST AND
WEAKENING IT AS IT MOVE INTO AREA OF HIGH SHEAR.
