SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND 
SOUTH PACIFIC OCEANS/280600Z-290600ZDEC2024//
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 91P) PREVIOUSLY LOCATED 
NEAR 14.8S 171.5E IS NOW LOCATED NEAR 15.0S 172.0E, APPROXIMATELY 
352 NM WEST-NORTHWEST OF NADI, FIJI. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY INDICATES A COMPACT BUT WELL-FORMED AREA OF 
DEEP CONVECTION EMBEDDED WITHIN THE SOUTH PACIFIC CONVERGENCE ZONE 
(SPCZ) WITH PULSATING OVERSHOOTING CLOUD TOPS NEAR THE CENTER. A 
12282203Z ASCAT METOP-B PASS INDICATES A CONTINUALLY STRENGTHENING 
AND RELATIVELY SYMMETRIC CIRCULATION WITH CONSISTENT STRONG WINDS 
WRAPPING INTO THE CENTER OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS
INDICATES FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL 
WIND SHEAR (10-15KTS), GOOD UPPER LEVEL OUTFLOW AND WARM SEA SURFACE 
TEMPERATURES (28-29C). GLOBAL DETERMINISTIC MODELS ARE IN AGREEMENT 
THAT 91P WILL CONTINUE TO CONSOLIDATE OVER THE NEXT 24 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
