1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 18AUG24 0000Z, TROPICAL STORM 08W (AMPIL) WAS LOCATED NEAR 
39.5N 152.5E, APPROXIMATELY 522 NM EAST OF MISAWA, JAPAN, AND HAD TRACKED 
EAST-NORTHEASTWARD AT 23 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 60 KNOTS GUSTING TO 75 KNOTS. SEE REF A 
(WTPN33 PGTW 180300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
25.0N 122.4E IS NOW LOCATED NEAR 24.9N 126.2E, APPROXIMATELY 256 NM EAST 
OF TAIPEI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 180150Z PARTIAL 
ASCAT METOP-B 25KM IMAGE REVEALS AN AREA OF BROAD CONVECTION WITH A 
SLOWLY CONSOLIDATING CIRCULATION ALONG THE NORTHERN PERIPHERY OF THE 
CONVECTION. ENVIRONMENTAL ANALYSIS IS MARGINALLY FAVORABLE, WITH LOW (5-
10KTS) VERTICAL WIND SHEAR, MODERATE UPPER LEVEL OUTFLOW, AND HIGH (30-
32C) SEA SURFACE TEMPERATURES. DETERMINISTIC AND ENSEMBLE MODELS ARE IN 
AGREEMENT THAT THE AREA OF CONVECTION (98W) WILL CONTINUE TO TRANSIT 
NORTHWARD INTO THE EAST CHINA SEA AS IT SLOWLY DEVELOPS OVER THE NEXT 24 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 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 REMAINS 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.//
