WTXS21 PGTW 20060404 20:30z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE FORMATION ALERT/042021ZAPR2006// RMKS/ 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 130 NM EITHER SIDE OF A LINE FROM 13.6S 115.5E TO 17.7S 113.5E WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF NUM- BERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT IMAGERY AT 041730Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 14.8S 114.9E. THE SYSTEM IS MOVING SOUTH-SOUTHWESTWARD AT 06 KNOTS. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.3S 115.2E IS NOW LOCATED NEAR 14.8S 114.9E, APPROXIMATELY 445 NM NORTH OF LEARMONTH, AUSTRALIA. RECENT ENHANCED WATER VAPOR IMAGERY REVEALS AN INCREASE IN RADIAL OUTFLOW AND A DEVELOPING POLEWARD OUTFLOW CHANNEL. UPPER LEVEL ANALYSIS INDICATES THE LOW LEVEL CIRCULATION CENTER (LLCC) IS SITUATED EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS AND NOW BEGINNING TO TRACK POLEWARD INTO THE RIDGE. ADDITIONALLY, THE LLCC IS IN AN ENVIRONMENT OF LOW TO MODERATE VERTICAL WIND SHEAR WITH FAVORABLE DIVERGENCE ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTI- MATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD. 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 052030Z.// ========================================================================= WTXS31 PGTW 20060405 09:00z MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC// SUBJ/TROPICAL CYCLONE WARNING// REF/A/NAVPACMETOCCEN PEARL HARBOR HI/042021ZAPR2006// AMPN/TROPICAL CYCLONE FORMATION ALERT// RMKS/ 1.

RECENT MULTI- SPECTRAL SATELLITE IMAGERY REVEALS THAT THE LOW LEVEL CIRCULATION CENTER (LLCC) IS EXPOSED NORTHEAST OF THE CENTRAL DENSE OVERCAST. THE SYSTEM HAS NOT MOVED AS FAR WESTWARD AS ANTICIPATED. A WEAK UPPER LEVEL LOW TO THE SOUTHWEST OF THE STORM HAS NOT FILLED AS EXPECTED. THIS HAS CAUSED A WEAKNESS IN THE RIDGE TO REMAIN, RESULTING IN A MORE POLEWARD TRACK. VERTICAL WIND SHEAR IS HIGHER THAN FORECAST AS WELL, AS EVIDENCED BY THE EXPOSED LLCC. AN OUT- FLOW CHANNEL HAS DEVELOPED AS TS 21S MOVES CLOSER TO THE MIDLAT- ITUDE WESTERLY FLOW. THIS IS EXPECTED TO CAUSE BRIEF INTENSIFI- CATION BEFORE INCREASED VERTICAL WIND SHEAR, COOLER SEA SURFACE TEMPERATURES AND LANDFALL COMBINE TO WEAKEN THE STORM PAST TAU 24.
