SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/100600Z-110600ZJUN2025//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
15.2N 115.7E IS NOW LOCATED NEAR 14.7N 115.0E, APPROXIMATELY 334 NM 
WEST OF MANILA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS AN EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC), WITH FLARING 
CONVECTION NEAR THE LLCC. A PARTIAL 092300Z ASCAT (METOP-C) MICROWAVE 
IMAGE SHOWS A CLOSED CIRCULATION WITH THE STRONGEST WINDS 
(APPROXIMATELY 20KTS) IN THE SOUTHERN PORTION OF THE INVEST.
ENVIRONMENTAL ANALYSIS REVEALS MARGINALLY FAVORABLE CONDITIONS FOR 
DEVELOPMENT WITH GOOD EQUATORWARD UPPER-LEVEL OUTFLOW, WARM SEA 
SURFACE TEMPERATURES (SST) OF 29-30C, AND LOW TO MODERATE WIND SHEAR 
(15-20 KNOTS). DETERMINISTIC AND ENSEMBLE MODELS ARE IN GOOD AGREEMENT 
THAT 92W WILL STEADILY DEVELOP WHILE TRACKING TOWARDS THE NORTHWEST 
OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
999 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 999 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.
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.//
