SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/290600Z-300600ZDEC2025//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   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 99P) PREVIOUSLY LOCATED NEAR 
13.4S 170.1W IS NOW LOCATED NEAR 13.4S 169.7W, APPROXIMATELY 77.3 NM 
NORTHEAST OF PAGO PAGO. MULTISPECTRAL SATELLITE IMAGERY DEPICTS BROAD 
CYCLONIC TURNING WITH ASSOCIATED FRAGMENTED BANDING AND DEEP CONVECTION, 
ESPECIALLY OVER THE NORTHEASTERN PORTION OF THE DEVELOPING CIRCULATION. 
ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
WITH LOW VERTICAL WIND SHEAR (10 TO 15 KNOTS), WARM SEA SURFACE 
TEMPERATURES (29 TO 30 C), AND MODERATE POLEWARD OUTFLOW. GLOBAL 
DETERMINISTIC AND ENSEMBLE MODELS DEPICT INCREASING CONSOLIDATION OVER 
THE NEXT 24 TO 48 HOURS AS INVEST 99P MOVES EASTWARD. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
