      (1) THE AREA OF CONVECTION (INVEST 96S) PREVIOUSLY LOCATED
NEAR 9.2S 89.7E IS NOW LOCATED NEAR 9.6S 89.4E, APPROXIMATELY 460NM
WEST-NORTHWEST OF THE COCOS ISLANDS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A STRONG BAND OF FLARING CONVECTION
WRAPPING FROM THE NORTH INTO A PARTIALLY EXPOSED LOW LEVEL
CIRCULATION (LLC). ANALYSIS INDICATES THERE IS A MARGINAL
ENVIRONMENT WITH MODERATE TO HIGH (20-30 KNOTS) VERTICAL WIND SHEAR
(VWS) TO THE NORTH OF 96S AND MODERATE TO WEAK (10-15 KNOTS) VWS TO
THE SOUTH. THE STRONG VWS IS BEING OFFSET BY FAIR RADIAL OUTFLOW,
DIVERGENCE ALOFT AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL
MODELS ARE IN GENERAL AGREEMENT ON A SOUTHWARD TO SOUTHWESTWARD
TRACK WITH GFS PREDICTING MORE AGGRESSIVE DEVELOPMENT OVER THE NEXT
36-48 HOURS AS 96S MOVES INTO MORE FAVORABLE VWS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

評級Low
(1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED
NEAR 17.5S 48.4E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING.
SEE PARA. 2.A.(1) FOR FURTHER DETAILS.
      (2) AN AREA OF CONVECTION (INVEST 96S) HAS PERSISTED NEAR 8.6S
89.3E, APPROXIMATELY 493NM WEST-NORTHWEST OF THE COCOS ISLANDS.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 231226Z SSMIS
91GHZ MICROWAVE IMAGE DISPLAY DISORGANIZED CONVECTION AROUND A BROAD
LLC. A 230349Z ASCAT-B IMAGE SHOWS SHARP TROUGHING WITH 15-20KT
WINDS OVER THE EASTERN PERIPHERY OF THE AREA.  ENVIRONMENTAL
ANALYSIS INDICATES MARGINALLY FAVORABLE CONDITIONS DEFINED BY FAIR
OUTFLOW AND MODERATE TO HIGH (20-30 KNOTS) VERTICAL WIND SHEAR
OFFSET BY WARM (29-30C) SEA SURFACE TEMPERATURES. ECMWF AND GFS ARE
IN GENERAL AGREEMENT ON THE SOUTHWARD TO SOUTHWESTWARD TRACK OF
INVEST 96S WITH GFS PREDICTING MORE AGGRESSIVE DEVELOPMENT OVER THE
NEXT TWO DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15
TO 20 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.
