好像MEDIUM 1~2添了  都沒人理呀...
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.3S 93.7E,
IS NOW LOCATED NEAR 8.5S 93.2E, APPROXIMATELY 306 NM SOUTHEAST OF
COCOS ISLAND. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS A
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH CURVED DEEP
CONVECTIVE BANDING, PRIMARILY OVER THE SOUTHERN SEMICIRCLE. A
121529Z MICROWAVE IMAGE INDICATES IMPROVED STRUCTURE WITH DEEP
CONVECTIVE BANDING WRAPPING INTO THE SOUTHEASTERN QUADRANT OF THE
LLCC WITH WEAK BANDING OVER THE NORTHERN SEMI-CIRCLE. UPPER-LEVEL
ANALYSIS SHOWS A MARGINAL ENVIRONMENT WITH WEAK TO MODERATE (10 TO
20 KNOTS) VERTICAL WIND SHEAR OFFSET BY STRONG DIFFLUENCE ALOFT.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
