REMARKS:
060300Z POSITION NEAR 19.5S 146.5W.
06DEC25. TROPICAL CYCLONE 06P (SIX), LOCATED APPROXIMATELY 165 NM
EAST‐SOUTHEAST OF PAPEETE, TAHITI, HAS TRACKED SOUTHWARD AT 13
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS THE SYSTEM HAS LOST MUCH OF ITS CENTRAL
CONVECTION DUE TO SHEAR AND IS NOW POSITIONED WITHIN THE
BAROCLINIC ZONE. SEA SURFACE TEMPERATURES WILL SOON DROP BELOW 28 C
AND THE CIRCULATION WILL ENCOUNTER 30+ KNOT WIND SHEAR WHICH WILL
DEGRADE THE REST OF THE SYSTEM STRUCTURE. TROPICAL CYCLONE 06P WILL
COMPLETE SUBTROPICAL TRANSITION BY TAU 12. THIS IS THE FINAL WARNING
ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE
SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MINIMUM
CENTRAL PRESSURE AT 060000Z IS 1000 MB. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 060000Z IS 16 FEET.//

Tropical Disturbance Summary For area Equator to 25S, 160E to 120W
ISSUED FROM RSMC NADI Dec 060802 UTC.

TROPICAL DEPRESSION 02F CENTRE [1000HPA] WAS ANALYSED NEAR 20.2S
146.0W AT 060600UTC. POSITION GOOD POOR ON HIMAWARI-8 IR IMAGERY WITH
ANIMATION. TD02F MOVING SOUTHEAST AT ABOUT 10 KNOTS.

THE LLCC IS FULLY EXPOSED AND CONVECTION REMAINS PERSISTENT TO THE
EAST OF THE CENTRE. THE SYSTEM LIES IN AN AREA WITH MODERATE UPPER
DIVERGENCE AND MODERATE SHEAR. SST AROUND 27 DEGREES CELSIUS. GLOBAL
MODELS HAVE PICKED UP THIS SYSTEM AND MOVE IT SOUTHEASTWARDS WHILE
QUICKLY WEAKENING IT.

THE POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE IN
THE NEXT 24 HOURS IS VERY LOW.

*****************************************************************

NO OTHER TROPICAL DISTURBANCE ANALYSED OR FORECAST IN THE AREA.

Tropical Disturbance Summary For area Equator to 25S, 160E to 120W
ISSUED FROM RSMC NADI Dec 062226 UTC.

TROPICAL DEPRESSION 02F CENTRE [1004HPA] WAS ANALYSED NEAR 24.5S
143.4W AT 062100UTC. POSITION POOR ON HIMAWARI-8 VIS IMAGERY WITH
ANIMATION. TD02F MOVING SOUTH-SOUTHEAST AT ABOUT 15 KNOTS.

THE LLCC IS FULLY EXPOSED AND CONVECTION REMAINS PERSISTENT TO THE
EAST OF THE CENTRE. THE SYSTEM LIES IN AN AREA WITH MODERATE UPPER
DIVERGENCE AND MODERATE SHEAR. SST AROUND 27 DEGREES CELSIUS. GLOBAL
MODELS HAVE PICKED THIS SYSTEM TO BE MOVING SOUTHEASTWARDS AND
QUICKLY WEAKENING IT.

THE SYSTEM IS EXPECTED TO EXIT NADI'S AREA OF RESPONSIBILITY FROM
TODAY AND ENTER INTO NZ AREA OF RESPONSIBILITY. ALL THE WARNING
RESPONSIBILITY OF TD02F WILL BE HANDLED BY NZ MET SERVICE.  

THE POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS VERY LOW.

THIS WILL BE THE LAST TROPICAL DISTURBANCE SUMMARY FOR TD02F UNLESS
THE SITUATION CHANGES.
