1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 17SEP24 0000Z, TROPICAL STORM 15W (PULASAN) WAS LOCATED 
NEAR 18.5N 138.7E, APPROXIMATELY 771 NM SOUTHEAST OF KADENA AB, AND HAD 
TRACKED WEST-NORTHWESTWARD AT 19 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 KNOTS. 
SEE REF A (WTPN32 PGTW 170300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
17.3N 124.6E IS NOW LOCATED NEAR 17.6N 120.7E, APPROXIMATELY 355 NM 
NORTH OF MANILA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A 
DISORGANIZED BROAD AREA OF LOW-LEVEL CIRCULATION (LLC) WITH CONVECTION 
OVER THE SOUTH CHINA SEA. A PARTIAL 120230Z ASCAT-C IMAGE SHOWS 10-20 
KNOTS EASTERLY WINDS OVER THE NORTHERN SEMICIRCLE OF THE BROAD 
CIRCULATION. GLOBAL MODELS INDICATE THE SYSTEM IS EXPECTED TO TRACK 
WESTWARD WHERE IT WILL FIND FAVORABLE CONDITIONS FOR DEVELOPMENT, 
INCLUDING LOW VERTICAL WIND SHEAR OF 5-10 KNOTS, WEAK EQUATORWARD 
OUTFLOW, AND WARM SEA SURFACE TEMPERATURES OF 30-31 DEGREES C. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS HIGH. SEE REF B (WTPN22 PGTW 161300) 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.//
