20170220.0552.goes-15.ir.93P.INVEST.15kts.1010mb.16.3S.172.4W.100pc.jpg

TROPICAL DISTURBANCE TD15F CENTRE [1000HPA] ANALYSED NEAR 18.4S
171.1W AT 200900UTC.
POSITION POOR BASED ON HIMAWARI-8 IR/EIR IMAGERY AND PERIPHERAL
SURFACE OBSERVATION. TD15F SLOW MOVING.

CONVECTION REMAINS PERSISTENT BUT ORGANISATION REMAINS POOR. SYSTEM
LIES JUST SOUTH OF AN UPPER RIDGE IN A MODERATE SHEARED ENVIRONMENT.
CYCLONIC CIRCULATION EXTENDS UPTO 700HPA. SST IS AROUND 30 DEGREES
CELSIUS.

GLOBAL MODELS HAVE PICKED UP THE SYSTEM AND SLOWLY MOVE IT
SOUTHEASTWARDS WITH SOME INTENSIFICATION.

POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE IN THE
NEXT 24 TO 48 HOURS IS LOW.

JTWC 00Z跳過任何評級直接升格編號07P,巔峰上望45節。

看來是根據風場決定升格的
