1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 29AUG23 1200Z, TROPICAL STORM 10W (HAIKUI) WAS LOCATED 
NEAR 19.1N 137.2E, APPROXIMATELY 411 NM SOUTHWEST OF IWO TO, AND HAD 
TRACKED WESTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS GUSTING TO 65 
KNOTS. SEE REF A (WTPN33 PGTW 291500) FOR FURTHER DETAILS.
      (2) AT 29AUG23 1200Z, SUPER TYPHOON 09W (SAOLA) WAS LOCATED NEAR 
19.3N 122.7E, APPROXIMATELY 298 NM NORTH-NORTHEAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED NORTHWESTWARD AT 06 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 135 KNOTS 
GUSTING TO 165 KNOTS. SEE REF B (WTPN32 PGTW 291500) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED 
NEAR 11.1N 154.7E IS NOW LOCATED NEAR 11.0N 153.6E, APPROXIMATELY 
541 NM EAST-SOUTHEAST OF GUAM. ANIMATED PROXYVIS SATELLITE IMAGERY 
DEPICTS A MOSTLY OBSCURED LLCC ENVELOPED BY PERSISTENT CONVECTION, 
WHICH IS FURTHER EVIDENT IN A 291508Z AMSR-2 89GHZ MICROWAVE IMAGE. 
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR 
INTENSIFICATION DUE TO LOW (10-15KT) VWS, WARM (30C) SSTS, AND GOOD 
POLEWARD AND EQUATORWARD OUTFLOW. GLOBAL MODELS AGREE THAT 94W WILL 
INTENSIFY AS IT FOLLOWS A NORTHWESTWARD TRACK OVER THE NEXT FEW DAYS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS HIGH. SEE REF C (WTPN21 PGTW 291800) FOR FURTHER 
DETAILS.
      (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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO HIGH.//
