WTIO21 PGTW 100200
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 4.2N 93.7E TO 9.6N 89.7E WITHIN
THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE
OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE
AREA ARE ESTIMATED TO BE 28 TO 32 KNOTS. METSAT IMAGERY AT 092330Z
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 5.4N 93.2E. THE
SYSTEM IS MOVING NORTHWARD AT 08 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 4.6N
93.2E, IS NOW LOCATED NEAR 5.4N 93.2E, APPROXIMATELY 130 NM WEST OF
BANDA ACEH, SUMATRA. ENHANCED WATER VAPOR ANIMATION DEPICTS FLARING
CONVECTION ASSOCIATED WITH A CONSOLIDATING LOW LEVEL CIRCULATION
CENTER (LLCC). A 092305Z SSMIS IMAGE REVEALS CONVECTIVE BANDING
DEVELOPING OVER THE SOUTHERN SEMICIRCLE AND WRAPPING INTO THE LLCC.
UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS APPROXIMATELY 5 DEGREES
SOUTH OF THE SUBTROPICAL RIDGE WITH 20 TO 30 KNOTS OF VERTICAL WIND
SHEAR. HOWEVER, THERE IS EXCELLENT POLEWARD AND EQUATORWARD OUTFLOW
AS EVIDENT IN THE ENHANCED WATER VAPOR ANIMATION. SEA SURFACE
TEMPERATURES ARE ABOVE 28 DEGREES CELSIUS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 28 TO 32 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1000 MB. DUE TO INCREASED CONSOLIDATION OF THE
LLCC, DEVELOPMENT OF CONVECTIVE BANDING, AND THE EXCELLENT UPPER
LEVEL OUTFLOW, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
