突然就Medium再TCFA了……底層確實發展起來了。

5. 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
   
6. 200 NM EITHER SIDE OF A LINE FROM 13.5S 76.1E TO 22.5S 80.1E WITHIN
   
7. THE NEXT 03 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF
   
8. NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA
   
9. ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT IMAGERY AT 281400Z
   
10. INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 14.4S 76.7E. THE
    
11. SYSTEM IS MOVING SOUTH-SOUTHEASTWARD AT 11 KNOTS.
    
12. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.0S
    
13. 76.6E IS NOW LOCATED NEAR 14.4S 76.7E, APPROXIMATELY 495 NM SOUTH-
    
14. SOUTHEAST OF DIEGO GARCIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
    
15. DEPICTS A RAPIDLY CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC)
    
16. WITH IMPROVED DEEP CONVECTIVE BANDING WRAPPING INTO A WELL-DEFINED
    
17. CENTER. A 281101Z SSMIS 91GHZ IMAGE SHOWS A COMPACT SYSTEM,
    
18. APPROXIMATELY 120NM DIAMETER, WITH TIGHTLY-CURVED DEEP CONVECTIVE
    
19. BANDING. A 280445Z ASCAT IMAGE REVEALS 25 TO 30 KNOT WINDS OVER THE
    
20. NORTHEASTERN QUADRANT. UPPER-LEVEL ANALYSIS REVEALS A FAVORABLE
    
21. ENVIRONMENT WITH RADIAL OUTFLOW AND LOW VERTICAL WIND SHEAR. DUE TO
    
22. THE SMALL SIZE OF THE LLCC, DYNAMIC MODELS ARE POORLY INITIALIZING
    
23. THE SYSTEM, HOWEVER, THE SYSTEM IS EXPECTED TO ACCELERATE SOUTHWARD
    
24. BETWEEN ENHANCED FLOW BETWEEN A DEEP TROUGH AND A POLEWARD-ORIENTED
    
25. SUBTROPICAL RIDGE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
    
26. 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
    
27. 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
    
28. CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.

38. 
    
39. THE SYSTEM IS EXPECTED TO TRACK RAPIDLY SOUTHWARDS A HAED OF THE TROUGH. THE NORTHWESTERLY VERTICAL WIND SHEAR ( 9K AT 00Z ACCORDING TO CIMMS DATA) IS FORECASTED TO STRENGTHEN, BUT ITS IMPACT ON THE SYSTEM MAY BE LIMITATED IN A FIRST TIME DUE TO THE SPEED OF THE SOUTHWARD TRACK. THE SYSTEM IS HOWEVER FORECAST TO WEAKEN ON WEDNESDAY, AND GOES ON SOUTHWARDS BEFORE TO MERGE WITH THE TROUGH AT THE END OF THE WEEK.

法國氣象局事後大幅提升強度（45節、992百帕），升格成為無名的中等熱帶風暴。
