JTWC : LOW

SHYUDOL

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.
