SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/140600Z-150600ZFEB2025//
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 16P) PREVIOUSLY LOCATED NEAR 
23.5S 168.1E IS NOW LOCATED NEAR 22.5S 170.2E, APPROXIMATELY 211 NM EAST 
OF NOUMEA, NEW CALEDONIA. THIS SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND 
MIDLATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND 
A 140251Z AMSR2 89GHZ MICROWAVE IMAGE DEPICT A FULLY EXPOSED LOW LEVEL 
CIRCULATION CENTER (LLCC) WITH SHEARED CONVECTION IN THE SOUTHERN 
PERIPHERY. A 132131Z ASCAT METOP-C PASS REVEALS HIGHER WINDS (35-40KTS) IN 
THE SOUTHWESTERN PORTION. ENVIRONMENTAL ANALYSIS INDICATES A MODERATELY 
UNFAVORABLE ENVIRONMENT FOR TROPICAL TRANSITION WITH A DEEP LAYER OF DRY 
AIR OVERTOP THE SYSTEM, MODERATE WESTERLY FLOW ALOFT AND BORDERLINE SEA 
SURFACE TEMPERATURES OF 26-27 C. GLOBAL MODELS ARE IN AGREEMENT THAT AS 
16P SLOWLY TRANSITIONS SOUTH WINDS WILL SLIGHTLY INTENSIFY DUE TO 
BAROLCINIC FORCING BEFORE THE SYSTEM BECOMES ABSORBED INTO THE LONG WAVE 
PATTERN. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN 
DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED 
FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 38 TO 
43 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 994 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE 
NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
