Invest 95W, remnants of TC 02S(TERATAI), remnants of TC 05B(JAWAD), 06/06utc updates




WESTERN NORTH PACIFIC/PHILIPPINE SEA: INVEST 95W. 15KNOT SYSTEM. NOT MENTIONNED YET FOR ANY DEVELOPMENT NEXT 24HOURS BUT KEEPING TABS ON IT.



SOUTHERN HEMISPHERE/SOUTH INDIAN OCEAN: REMNANTS OF TC 02S(TERATAI). JTWC ADVISORY(ABIO) ISSUED AT 05/18UTC.

THE AREA OF CONVECTION (REMNANTS OF TC 02S) PREVIOUSLY  LOCATED NEAR 7.4S 98.3E IS NOW LOCATED NEAR 8.3S 100.3E,  APPROXIMATELY 580 KM NORTHEAST OF COCOS ISLANDS. ANIMATED ENHANCED  INFRARED SATELLITE IMAGERY DEPICTS DISORGANIZED CONVECTION OBSCURING  A WEAK LOW LEVEL CIRCULATION. RECENT SCATTEROMETRY DATA INDICATES A  WELL DEFINED LOW LEVEL CIRCULATION WITH SMALL POCKETS OF HIGHER  WINDS (25-30 KTS) IN THE NORTHERN AND SOUTHERN SEMI-CIRCLES, WHICH  ARE ASSOCIATED WITH THUNDERSTORM ACTIVITY. ENVIRONMENTAL ANALYSIS  CONTINUES TO INDICATE MARGINAL CONDITIONS FOR DEVELOPMENT WITH  ROBUST POLEWARD OUTFLOW ALOFT AND WARM (28-29C) SEA SURFACE  TEMPERATURES, OFFSET BY VERY HIGH (30-40KT) VERTICAL WIND SHEAR.  GLOBAL MODELS ARE STILL IN AGREEMENT THAT THE REMNANTS OF TC 02S  WILL TRACK EASTWARD BEFORE RECURVING TO THE SOUTHWEST. DETERMINISTIC  MODELS SUCH AS NAVGEM, GFS AND CFC, ALONG WITH A HANDFUL OF ENSEMBLE  MEMBERS FROM BOTH ECMWF AND GFS, AGREE THAT THE REMNANTS OF TC 02S  MAY RE-INTENSIFY AFTER MAKING THE SWING TO THE SOUTHWEST. MAXIMUM  SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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 REMAINS LOW.
