1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 05OCT23 0000Z, TYPHOON 14W (KOINU) WAS LOCATED NEAR 22.0N 
120.8E, APPROXIMATELY 190 NM SOUTH- SOUTHWEST OF TAIPEI, TAIWAN, AND HAD 
TRACKED WEST-NORTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 110 KNOTS GUSTING TO 135 KNOTS. 
SEE REF A (WTPN31 PGTW 050300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR 7.1N 
157.1E, APPROXIMATELY 66 NM WEST OF POHNPEI, MICRONESIA.  
ANIMATED MULTISPECTRAL SATELLITE IMAGERY, ALONG WITH AN AMSR2 89GHZ 
MICROWAVE IMAGE, DEPICT AN ILL-DEFINED LOW-LEVEL CIRCULATION WITH A BROAD 
AREA OF FRAGMENTED CONVECTION ON THE SOUTHWEST QUADRANT. UPPER-LEVEL 
ANALYSIS INDICATES DIVERGENCE ALOFT WITH MODERATE EQUATORWARD OUTFLOW, 
LOW (10-15 KTS) VERTICAL WIND SHEAR (VWS), AND VERY WARM (30-31C) SEA 
SURFACE TEMPERATURES (SSTS). GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 98W 
WILL TRACK GENERALLY WEST-NORTHWESTWARD AND CONTINUE TO DEVELOP OVER THE 
NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 
TO 17 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS 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.//
