1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 21SEP26 0000Z, TYPHOON 24W (DUJUAN) WAS LOCATED NEAR 
32.4N 138.7E, APPROXIMATELY 181 NM SOUTH-SOUTHWEST OF YOKOSUKA, JAPAN, 
AND HAD TRACKED NORTH- NORTHEASTWARD AT 13 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 KNOTS 
GUSTING TO 80 KNOTS. SEE REF A (WTPN31 PGTW 210300) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
11.3N 144.3E IS NOW LOCATED NEAR 13.3N 144.3E, APPROXIMATELY 127 NM 
SOUTH OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS 
91W AS A BROAD LOW LEVEL TURNING WITH DISORGANIZED CONVECTION.  
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT 
WITH LOW VERTICAL WIND SHEAR (15 KNOTS OR LESS), GOOD UPPER-LEVEL 
DIFFLUENT OUTFLOW, AND WARM (29-30 C) SEA SURFACE TEMPERATURES. GLOBAL 
MODELS ARE IN GENERAL CONSENSUS ON STEADY INTENSIFICATION WITHIN 48 
HOURS WITH A NORTHWESTWARD TRACK. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (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.//
