172.0W [NEAR SAMOA] AT 042100UTC AND REMAIN SLOW MOVING.

CONVECTION HAS BEEN PERSISTENT OVER SUPPOSED LLCC IN THE LAST 12
HOURS, WHILE ORGANISATION REMAIN POOR.
TD03F CURRENTLY LIES IN A LOW SHEARED ENVIRONMENT WITH GOOD UPPER
DIVERGENCE AND GOOD POLEWARD OUT FLOW. SST IS AROUND 30 DEGREES
CELSIUS.
TD03F LIES ON THE PERIPHERY OF A SUBTROPICAL RIDGE [WITH ANTICYCLONIC
CENTRE LOCATED TO THE SOUTHEAST OF THE SYSTEM]. THUS, TD03F IS
EXPECTED TO GRADUALLY DRIFT TOWARDS THE SOUTH-SOUTHWEST BEFORE MAKING
A SOUTHEAST TURN TOWARDS TONGA WITHIN THE NEXT 24 HOURS.

GLOBAL MODELS HAVE PICK UP THE SYSTEM AND MOVE IT TOWARDS THE
SOUTHEAST WITH SOME INTENSIFICATION.
