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 15.3N 144.4E IS NOW LOCATED NEAR 16.5N 143.4E, APPROXIMATELY 202 
NM NORTH-NORTHWEST 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. ANALYSIS REVEALS THAT 90W IS IN AN 
OVERALL FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH GOOD 
EQUATORWARD OUTFLOW ALOFT AND WARM SEA SURFACE TEMPERATURES (30C) 
OFFSET BY MODERATE (15-20 KTS) VERTICAL WIND SHEAR. GLOBAL MODELS ARE 
IN GOOD AGREEMENT THAT 90W WILL GENERALLY TRACK NORTH-NORTHWESTWARD 
AS THE SYSTEM GRADUALLY INTENSIFIES OVER THE NEXT 24-48 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 IS UPGRADED TO HIGH. SEE REF B (WTPN21 PGTW 
210800) 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.//
