1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04SEP25 1800Z, TROPICAL STORM 21W (PEIPAH) WAS LOCATED NEAR 
33.1N 132.8E, APPROXIMATELY 80 NM SOUTH-SOUTHEAST OF IWAKUNI, JAPAN, AND 
HAD TRACKED NORTHEASTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 KNOTS. 
SEE REF A (WTPN31 PGTW 042100) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 97W) HAS PERSISTED NEAR 17.3N 
119.4E, APPROXIMATELY 58 NM WEST-SOUTHWEST OF VIGAN. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A WEAKLY DEFINED 
CIRCULATION CENTER THAT IS OBSCURED BY FLARING CONVECTION IN THE 
NORTHERN PERIPHERY OF 97W. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES 
A FAVORABLE CONDITIONS FOR DEVELOPMENT WITH 15-20 KTS OF VERTICAL WIND 
SHEAR, WARM SEA SURFACE TEMPERATURES (29-30 C), AND MODERATE EQUATORWARD 
OUTFLOW ALOFT. GLOBAL DETERMINISTIC MODELS ARE IN GOOD AGREEMENT THAT 
97W WILL DEVELOP AND TRACK NORTHWARD SOUTHWEST OF TAIWAN, WITH GFS 
INDICATING FASTER DEVELOPMENT. ENSEMBLES ARE IN GOOD AGREEMENT THAT 97W 
WILL TRACK NORTHWARD WITH ECENS BEING THE MORE AGGRESSIVE AND FAVORS THE 
DEVELOPMENT SOUTHWEST OF TAIWAN.  MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (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: ADDED LOW AREA IN PARA. 1.B.(1).//
