SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/150600Z-160600ZSEP2026//
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 
13.0N 152.7E IS NOW LOCATED NEAR 15.1N 150.9E, APPROXIMATELY 372 NM 
EAST-SOUTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A BROAD, PARTIALLY EXPOSED LOW-LEVEL CIRCULATION (LLC) WITH 
PERSISTENT CONVECTION BUILDING OVER THE CENTER. ENVIRONMENTAL ANALYSIS 
REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND 
SHEAR (5 TO 15KTS), DUAL-CHANNEL UPPER-LEVEL OUTFLOW, AND WARM SEA 
SURFACE TEMPERATURES (29 TO 30 C). GLOBAL DETERMINISTIC AND ENSEMBLE 
MODELS ARE IN GOOD AGREEMENT ON 90W FURTHER CONSOLIDATING WITH A 
NORTH-NORTHWESTWARD TRACK OVER THE NEXT 24 HOURS MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 23 TO 28 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.
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.//
