SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS REISSUED/281800Z-290600ZDEC2025//
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 170.9W IS NOW LOCATED NEAR 13.4S 170.1W, APPROXIMATELY 63 NM 
NORTH-NORTHEAST OF PAGO PAGO, AMERICAN SAMOA. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY DEPICTS DEEP CONVECTION BUILDING OVER THE 
NORTHERN SEMICIRCLE OF A COMPACT LOW-LEVEL CIRCULATION CENTER (LLCC). 
ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
WITH MODERATE POLEWARD UPPER-LEVEL OUTFLOW, LOW VERTICAL WIND SHEAR (10 
TO 15 KTS), AND WARM SEA SURFACE TEMPERATURES (29 TO 30 C). GLOBAL 
MODELS AGREE ON 99P TRACKING GENERALLY EASTWARD AS IT FURTHER 
CONSOLIDATES OVER THE NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 25 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
MEDIUM.//
