1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 03SEP23 1200Z, TYPHOON 10W (HAIKUI) WAS LOCATED NEAR 
22.8N 120.2E, APPROXIMATELY 155 NM SOUTH-SOUTHWEST OF TAIPEI, TAIWAN, 
AND HAD TRACKED WESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 80 KNOTS GUSTING TO 100 
KNOTS. SEE REF A (WTPN33 PGTW 031500) FOR FURTHER DETAILS.
      (2) AT 03SEP23 1200Z, TROPICAL DEPRESSION 09W (SAOLA) WAS 
LOCATED NEAR 20.7N 109.0E, APPROXIMATELY 175 NM EAST OF HANOI, 
VIETNAM, AND HAD TRACKED SOUTHWESTWARD AT 04 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS 
GUSTING TO 35 KNOTS. SEE REF B (WTPN32 PGTW 031500) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (3) AT 03SEP23 0000Z, TROPICAL DEPRESSION 11W (KIROGI) WAS 
LOCATED NEAR 29.6N 141.9E, APPROXIMATELY 659 NM EAST-SOUTHEAST OF 
SASEBO, JAPAN, AND HAD TRACKED WEST- NORTHWESTWARD AT 08 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
25 KNOTS GUSTING TO 35 KNOTS. SEE REF C (WTPN31 PGTW 030300) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (4) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 
18.1N 138.8E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
35.7N 173.5E IS NOW LOCATED NEAR 36.2N 171.6E, APPROXIMATELY 747 NM 
NORTHWEST OF MIDWAY ATOLL. THE SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND 
MID-LATITUDE CYCLONE FEATURES. ANIMATED EIR DEPICTS AN ASYMMETRIC 
SYSTEM WITH A PARTIALLY-EXPOSED LLCC AND CONVECTION SHEARED TO THE 
SOUTH. THE ENVIRONMENT IS MARGINALLY UNFAVORABLE FOR DEVELOPMENT AS 
THERE IS A STRONG UPPER-LEVEL CUTOFF LOW JUST TO THE SOUTH CAUSING 
INCREASED VWS (40-50KTS) ACROSS THE LLCC, HINDERING OUTFLOW BUT 
SLIGHTLY OFFSET BY 25-27C SEA TEMPS. GLOBAL MODELS AGREE THAT INVEST 
98W WILL TRACK GENERALLY WESTWARD, WEAKEN AND DISSIPATE WITHIN THE 
NEXT 72 HOURS. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER 
CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO 
DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 35 TO 40 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1010 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
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.
3. JUSTIFICATION FOR REISSUE: UPDATED PARA. 1.A.(2) WITH 09W FINAL 
WARNING INFORMATION. DISSIPATED AREA IN PARA. 1.B.(1).//
