1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 07AUG24 0000Z, TROPICAL DEPRESSION 06W (SIX) WAS LOCATED 
NEAR 25.1N 141.0E, APPROXIMATELY 24 NM NORTHWEST OF IWO TO, JAPAN, 
AND HAD TRACKED SOUTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 
35 KNOTS. SEE REF A (WTPN31 PGTW 070300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
24.2N 131.6E IS NOW LOCATED NEAR 24.1N 126.6E, APPROXIMATELY 150 NM 
SOUTH-SOUTHWEST OF KADENA AB, OKINAWA. THIS VERY LARGE SYSTEM IS 
LOCATED WITHIN THE WESTERN PERIPHERY OF THE MONSOON GYRE, WHICH 
REMAINS ENTRENCHED OVER THE WESTERN NORTH PACIFIC, WITH AN EXTENSIVE 
SWATH OF 15-25 KNOT WEST-SOUTHWESTERLY TO SOUTHWESTERLY WINDS FROM 
THE EAST PHILIPPINE SEA TO ABOUT 145E. SURFACE WINDS ACROSS THIS 
REGION RANGE FROM 10-15 KNOTS, REFLECTING THE OVERALL WEAK NATURE OF 
THIS SYSTEM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS SEVERAL 
MESOVORTICES (23.1N 126.8E, 25.1N 126.8E, 24.6N 122.7E) ROTATING 
CYCLONICALLY AROUND THE CENTROID, WHICH REPRESENTS THE LOW-LEVEL 
CIRCULATION CENTER (LLCC). A 060442Z AMSR2 36 GHZ COLOR COMPOSITE 
MICROWAVE IMAGE INDICATES WEAK CONVECTIVE STRUCTURE, WITH ISOLATED 
CONVECTIVE BURSTS OVER THE WESTERN PERIPHERY. UPPER-LEVEL ANALYSIS 
INDICATES MARGINAL CONDITIONS, WITH WEAK DIFFLUENCE ALOFT AND LOW TO 
MODERATE (10-20 KNOTS) VERTICAL WIND SHEAR. SST VALUES ARE CONDUCIVE 
(30-31 C); HOWEVER, EXTENSIVE DRY AIR ENTRAINMENT IS HINDERING 
DEVELOPMENT. GLOBAL MODELS INDICATE A QUASI-STATIONARY TRACK MOTION 
SOUTH OF OKINAWA OVER THE NEXT TWO DAYS WITH NO SIGNIFICANT 
DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 12 TO 
17 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS LOW. 
      (2) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
26.3N 141.2E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 1.A.(1) FOR FURTHER DETAILS.
      (3) 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.(2) TO
WARNING STATUS.//
