1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 20AUG24 1800Z, TROPICAL DEPRESSION 10W (JONGDARI) WAS 
LOCATED NEAR 36.1N 125.5E, APPROXIMATELY 94 NM SOUTHWEST OF OSAN AB, 
AND HAD TRACKED NORTHWARD AT 18 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 20 KNOTS GUSTING TO 30 
KNOTS. SEE REF A (WTPN31 PGTW 202100) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR 
15.2N 145.3E IS NOW LOCATED NEAR 15.3N 144.4E, APPROXIMATELY 118 NM 
NORTH OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 210355Z 
AMSR2 89GHZ SATELLITE IMAGERY DEPICT AN AREA OF PERSISTENT DEEP 
CONVECTION, WITH FRAGMENTED FORMATIVE BANDING SLOWLY WRAPPING AROUND 
THE CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS THAT 90W IS IN A 
FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH GOOD EQUATORWARD 
OUTFLOW ALOFT, WARM SEA SURFACE TEMPERATURES (30C), AND LOW (15-20 
KTS) VERTICAL WINDSHEAR HINDERING DEVELOPMENT. GLOBAL MODELS ARE IN 
GOOD AGREEMENT THAT 90W WILL GENERALLY TRACK NORTH-NORTHWESTWARD AS 
THE SYSTEM GRADUALLY INTENSIFIES OVER THE NEXT 36-48 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 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.//
