AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
180 NM EITHER SIDE OF A LINE FROM 20.8S 178.9W TO 30.2S 176.3W
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 25 TO 30 KNOTS. METSAT
IMAGERY AT 020912Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 21.2S 178.7W. THE SYSTEM IS MOVING SOUTH-SOUTHEASTWARD AT 12
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 92P) PREVIOUSLY LOCATED 
NEAR 16.9S 179.8E IS NOW LOCATED NEAR 21.2S 178.7W APPROXIMATELY 
298 NM SOUTHEAST OF NADI, FIJI. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND A 091307Z AMSR2 89GHZ MICROWAVE PASS DEPICTS 
FORMATIVE BANDING WRAPPING INTO AN AREA OF LOW LEVEL CIRCULATION 
WITH FLARING CONVECTION IN THE EASTERN AND SOUTHERN PERIPHERIES. 
ENVIRONMENTAL ANALYSIS DEPICTS A MARGINAL ENVIRONMENT WITH FAIRLY 
GOOD UPPER LEVEL OUTFLOW ALOFT, MODERATE (15-20KTS) VERTICAL WIND 
SHEAR, AND WARM (28-29C) SEA SURFACE TEMPERATURES. NUMERICAL MODELS 
ARE IN GOOD AGREEMENT THAT INVEST 92P WILL CONTINUE TO TRACK TO THE 
SOUTH-SOUTHEAST OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. 
THIS SUPERSEDES REF A.
