1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 23DEC24 0000Z, TROPICAL DEPRESSION 28W (TWENTYEIGHT) WAS 
LOCATED NEAR 10.9N 112.7E, APPROXIMATELY 354 NM EAST OF HO CHI MINH 
CITY, VIETNAM, AND HAD TRACKED NORTHWESTWARD AT 07 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS 
GUSTING TO 40 KNOTS. SEE REF A (WTPN31 PGTW 230300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96P) PREVIOUSLY LOCATED NEAR 
19.7S 152.6E IS NOW LOCATED NEAR 20.4S 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.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: DOWNGRADED AREA IN PARA. 2.B.(1) TO LOW.//
