PACIFIC OCEANS/240600Z-250600ZSEP2023//
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 91W) PREVIOUSLY LOCATED NEAR
15.9N 117.4E IS NOW LOCATED NEAR 14.9N 113.0E, APPROXIMATELY 450 NM
SOUTH OF HONG KONG. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A
240152Z 89 GHZ MHS MICROWAVE IMAGE DEPICT A BROAD AREA OF LOW LEVEL
TURNING WITH DEEP CONVECTIVE BURSTS AND FORMATIVE BANDING PRESENT.
ENVIRONMENTAL ANALYSIS INDICATES THAT 91W IS IN A FAVORABLE ENVIRONMENT
FOR DEVELOPMENT WITH GOOD EQUATORWARD OUTFLOW ALOFT, LOW (10-15 KTS)
VERTICAL WIND SHEAR, AND WARM (30-31 C) SST. GLOBAL NUMERICAL
DETERMINISTIC AND ENSEMBLE MODELS ARE IN AGREEMENT THAT 91W WILL TRACK
SLOWLY WESTWARD AND CONTINUE TO DEVELOP OVER THE NEXT 48 HOURS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. 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.//
