過了一天 JTWC的評級沒啥變化 維持在LOW 不過他圓圓的好可愛 看看會不會成為2013-14年風季的第一旋 話說20kt了 (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.5S 68.2E, IS NOW LOCATED NEAR 9.9S 67.9E, APPROXIMATELY 310 NM WEST-SOUTHWEST OF DIEGO GARCIA. ANIMATED INFRARED SATELLITE IMAGERY REVEALS A WELL DEFINED LOW LEVEL CIRCULATION CENTER WITH PERSISTENT CENTRAL CONVECTION THAT HAS SHALLOWED OVER THE PAST FEW HOURS. A 311308Z TRMM MICROWAVE IMAGE SHOWS THE ORGANIZATION OF THE SYSTEM HAS NOT CHANGED OVER THE PAST TWELVE HOURS AS THE LLCC HAS REMAINED WELL- DEFINED AND CONVECTION HAS NOT INCREASED. UPPER LEVEL ANALYSIS REVEALS A INCREASINGLY UNFAVORABLE ENVIRONMENT AS DIFFLUENT EASTERLY AND POLEWARD OUTFLOW IS HINDERED BY INCREASING VERTICAL WIND SHEAR THAT IS NOW ASSESSED AT MODERATE TO HIGH (20-30 KNOTS) LEVELS. SEA SURFACE TEMPERATURES IN THE REGION ARE ALSO MODERATELY FAVORABLE AT 26 TO 28 DEGREES CELSIUS BUT SHARPLY DECREASE AS THE SYSTEM DRIFTS SOUTH. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. DUE TO THE INCREASINGLY UNFAVORABLE ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW. |
