SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/140600Z-150600ZSEP2026//
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 90W) PREVIOUSLY LOCATED NEAR 
12.8N 153.6E IS NOW LOCATED NEAR 13.0N 152.7E, APPROXIMATELY 342 NM 
NORTH OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A 
PARTIALLY EXPOSED, ELONGATED LOW LEVEL CIRCULATION WITH WIDESPREAD, 
PERSISTENT DEEP CONVECTION CONCENTRATED TO THE EQUATORWARD SIDE OF A 
MONSOON TROUGH. THE BROAD, POORLY DEFINED CIRCULATION HAS BEEN SLOWLY 
CONSOLIDATING OVER THE PAST 12 HOURS. ENVIRONMENTAL ANALYSIS REVEALS LOW 
VERTICAL WIND SHEAR (5-10 KTS), MODERATE RADIAL OUTFLOW, STRONG 
DIVERGENCE ALOFT, AND A WARM SEA SURFACE TEMPERATURE (29-30C), 
INDICATING HIGHLY FAVORABLE CONDITIONS FOR FURTHER DEVELOPMENT. THE 
DISORGANIZED STATE OF THE SYSTEM WILL LIMIT THE RATE OF DEVELOPMENT IN 
THE NEAR TERM. DETERMINISTIC AND ENSEMBLE GUIDANCE STRONGLY AGREE WITH 
GRADUAL DEVELOPMENT OVER THE NEXT 24-36 HOURS AS THE SYSTEM TRANSITS 
NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 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.//
