21S.Imelda 緯度漸高轉弱中

目前93S 已經測到 30 KTS 的風速
JTWC 也於剛剛將評級升等為 MEDIUM

該系統目前與附近其它雲系有逐漸分離
並且有開始獨立發展的趨勢
目前我真的是越來越看好它了 XD
現在整個印度洋呈現一個很熱鬧的狀態
陸續分別出現94S與95S
假使95S發展成功說不定有機會跟它產生互旋
這一點也值得給他繼續看下去

JTWC 於剛剛將93S
評級為LOW了

AN AREA OF CONVECTION HAS PERSISTED NEAR 8.6S 76.2E, APPROXIMATELY 240 NM EAST-SOUTHEAST OF DIEGO GARCIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS PERSISTENT BUT SHALLOW CONVECTION NEAR A BROAD LOW LEVEL CIRCULATION CENTER (LLCC). A 031023Z SSMI MICROWAVE SATELLITE IMAGE ALSO SHOWS SHALLOW CONVECTION WITH INCREASING ORGANIZATION. A 030649Z OSCAT PASS REVEALS 10-20 KT WINDS CLOSEST TO THE LLCC WITH 20-30 KT WINDS ALONG THE NORTHEASTERN PERIPHERY. UPPER LEVEL ANALYSIS INDICATES THE DISTURBANCE IS LOCATED APPROXIMATELY FIVE DEGREES SOUTH OF AN ANTICYCLONIC POINT SOURCE IN A REGION OF HIGH (20-30 KT) VERTICAL WIND SHEAR. RECENT ANIMATED WATER VAPOR IMAGERY DEPICTS INCREASING POLEWARD AND CROSS-EQUATORIAL OUTFLOW. 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 IS LOW.
