SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/300600ZJUN2025-010600ZJUL2025//

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
15.2N 134.1E IS NOW LOCATED NEAR 15.4N 132.6E, APPROXIMATELY 677 NM 
EAST OF MANILA, PHILIPPINES. MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A SLOWLY CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC) WITH 
BUILDING CONVECTION THROUGHOUT THE CIRCULATION. HOWEVER, A RECENT 
300028Z ASCAT-C PASS PORTRAYS THE SUSPECTED AREA TO BE A BROAD AREA OF 
TROUGHING. ENVIRONMENTAL ANALYSIS REVEALS A HIGHLY FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH LOW LEVEL VERTICAL WIND SHEAR (VWS) OF 
10-15 KNOTS, GOOD DUAL-CHANNEL UPPER-LEVEL OUTFLOW AND WARM SEA SURFACE 
TEMPERATURES (SST) OF 30-31 C. DETERMINISTIC AND ENSEMBLE MODELS 
INDICATE LOW LIKELIHOOD OF DEVELOPMENT OVER THE NEXT TWO DAYS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
