TROPCIAL CYCLONE FORMATION ALERT ISSUED AT 05/0530UTC.

THE AREA OF CONVECTION (INVEST 95P) PREVIOUSLY LOCATED NEAR  15.2S 172.2W IS NOW LOCATED NEAR 14.5S 168.0W, APPROXIMATELY 177 NM EAST  OF PAGO PAGO, AMERICAN SAMOA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY  (MSI) AND A 050109Z AMSR2 89GHZ MICROWAVE IMAGE DEPICT A CONSOLIDATED  CIRCULATION WITH PERSISTENT FLARING CONVECTION OVER ITS CENTER AND  FORMATIVE BANDING ON THE NORTHERN AND SOUTHERN PERIPHERIES WRAPPING  TOWARDS ITS CENTER. ENVIRONMENTAL CONDITIONS PROVE TO BE FAVORABLE FOR  FURTHER DEVELOPMENT CHARACTERIZED BY ROBUST EQUATORWARD AND POLEWARD  OUTFLOW ALOFT, LOW (10-15 KNOTS) VERTICAL WIND SHEAR (VWS), AND WARM  (29-30 C) SEA SURFACE TEMPERATURES (SST). GLOBAL NUMERICAL MODELS AGREE  ON THE TRACK OF INVEST 95P CONTINUING TO FLATTEN OUT AND MAKE AN EAST- SOUTHEASTWARD TURN, GENERALLY TOWARDS FRENCH POLYNESIA WITH GRADUAL  INTENSIFICATION OVER THE NEXT 12 TO 24 HOURS. INTENSITY GUIDANCE SHOWS A  CLEAR AGREEANCE FOR THE FIRST 24 HOURS ON THE SYSTEM GETTING UP TO 35  KNOTS THEN A SPLIT AROUND TAU 60 WITH SOME SHOWING A STEEP DECLINE AND  OTHERS INDICATING AN INCREASE IN INTENSITY. MAXIMUM SUSTAINED SURFACE  WINDS ARE ESTIMATED AT 28 TO 33 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 IS UPGRADED TO HIGH
