FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 145 NM EITHER SIDE OF A LINE FROM 11.2S4 130.7E1 TO 11.8S0 126.3E2 WITHIN THE NEXT 06 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 25 TO 30 KNOTS. METSAT IMAGERY AT 151730Z7 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 11.3S5 130.3E7. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 09 KNOTS. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.0S2 131.2E7 IS NOW LOCATED NEAR 11.3S5 130.3E7, APPROXIMATELY 90 NM NORTH-NORTHWEST OF DARWIN, AUSTRALIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY INDICATES SUSTAINED CYCLING DEEP CONVECTION OVER AN IMPROVED LOW LEVEL CIRCULATION CENTER (LLCC) AT THE SURFACE. RECENT MICROWAVE IMAGERY SHOWS INCREASED DEEP CONVECTION AND IMPROVED ORGANIZATION. UPPER LEVEL ANALYSIS INDICATES DECREASING VERTICAL WIND SHEAR IN THE REGION WITH MODERATE DIFFLUENCE ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 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 162030Z2. 4.
