SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/110600Z-120600ZSEP2023//
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 
23.1N 129.0E IS NOW LOCATED NEAR 23.0N 130.0E, APPROXIMATELY 235 NM 
SOUTH-SOUTHEAST OF KADENA AB, OKINAWA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS AN EXPOSED LLCC WITH FLARING CONVECTION. A 110126Z 
ASCAT-B PASS REVEALS ISOLATED 20 KT WINDS WEST OF THE CIRCULATION 
CENTER. ENVIRONMENTAL ANALYSIS INDICATES THAT 92W IS IN A MARGINALLY 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH WEAK OUTFLOW ALOFT AND DRY 
AIR ENTRAINMENT OFFSET BY LOW (10-15 KTS) VERTICAL WIND SHEAR AND WARM 
(28-29 C) SST. ADDITIONALLY, A DEEP UPPER-LEVEL TROUGH DIRECTLY OVER THE 
SYSTEM IS EXPECTED TO DEEPEN AND SUPPRESS DEVELOPMENT. GLOBAL MODELS 
SHOW THAT 92W WILL DRIFT SLOWLY SOUTHWARD OVER THE NEXT 48 HOURS 
WITH NO SIGNIFICANT DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 17 TO 22 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 1004 MB. DUE TO THE STRENGTH OF THE WIND FIELD, THE POTENTIAL 
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS UPGRADED TO 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.//
