1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 30AUG22 0000Z, TYPHOON 12W (HINNAMNOR) WAS LOCATED NEAR 
26.8N 137.4E, APPROXIMATELY 242 NM WEST-NORTHWEST OF IWO TO, AND HAD 
TRACKED WESTWARD AT 17 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 115 KNOTS GUSTING TO 140 KNOTS. SEE REF A 
(WTPN31 PGTW 300300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
21.4N 134.8E IS NOW LOCATED NEAR 20.8N 134.4E, APPROXIMATELY 349 NM 
SOUTH-SOUTHEAST OF MINAMI DAITO JIMA, JAPAN. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY (MSI) AND A 300408Z AMSR2 85GHZ MICROWAVE IMAGE DEPICT 
A BROAD LOW LEVEL CIRCULATION (LLC) WITH PERSISTENT DEEP CONVECTION 
DRIVING ENHANCED WINDS WITHIN THE SOUTHERN PERIPHERY OF THE LLC. ALTHOUGH 
ENVIRONMENTAL ANALYSIS REVEALS GENERALLY FAVORABLE CONDITIONS DEFINED BY 
POLEWARD OUTFLOW ALOFT, LOW (5-10KT) VWS, AND WARM (30-31) SEA SURFACE 
TEMPERATURES, THE CLOSE PROXIMITY TO TYPHOON 12W WILL RESULT IN A SMALL 
WINDOW FOR DEVELOPMENT INTO A WARNED TROPICAL CYCLONE. GLOBAL MODELS 
REVEAL A SHORT 24-36 HOUR WINDOW FOR THE LIMITED DEVELOPMENT OF 98W 
BEFORE THE SYSTEM GETS ABSORBED INTO THE SOUTHEASTERN PERIPHERY OF TY 
12W. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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 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.//
