1. REMARKS: THIS CANCELS REF A (WTPS21 PGTW 220600). THE AREA OF 
CONVECTION (INVEST 96P) PREVIOUSLY LOCATED NEAR 19.7N 152.6E IS NOW 
LOCATED NEAR 20.4N 156.2E, APPROXIMATELY 591 NM WEST OF NOUMEA. ANIMATED 
MULTISPECTRAL SATELLITE (MSI) IMAGERY DEPICTS AN ELONGATED, EXPOSED LOW 
LEVEL CIRCULATION CENTER (LLCC). THE SYSTEM IS CURRENTLY TRANSITIONING 
TO A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH 
TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ENVIRONMENTAL ANALYSIS 
REVEALS AN UNFAVORABLE ENVIRONMENT FOR TROPICAL DEVELOPMENT WITH A TIGHT 
GRADIENT OF VERTICAL WIND SHEAR OF 10-30 KNOTS, WEAK UPPER-LEVEL OUTFLOW 
AND WARM SEA SURFACE TEMPERATURES OF 27-28 C. GLOBAL DETERMINISTIC AND 
ENSEMBLE MODELS INDICATE THAT INVEST 96P WILL UNDERGO LIMITED 
DEVELOPMENT OVER THE NEXT 24-48 HOURS AS IT COMPLETES THE TRANSITION 
INTO A SUBTROPICAL SYSTEM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
995 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW.//
