1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 13AUG26 1800Z, TROPICAL STORM 16W (NANGKA) WAS LOCATED 
NEAR 28.3N 152.4E, APPROXIMATELY 261 NM NORTH-NORTHWEST OF MINAMI TORI 
SHIMA, AND HAD TRACKED EAST- NORTHEASTWARD AT 15 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTPN31 PGTW 132100) FOR FURTHER 
DETAILS.
      (2) AT 13AUG26 1800Z, TROPICAL DEPRESSION 13W (PEILOU) WAS 
LOCATED NEAR 33.8N 170.2E, APPROXIMATELY 891 NM NORTH-NORTHEAST OF 
WAKE ISLAND, AND HAD TRACKED NORTHEASTWARD AT 13 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS 
GUSTING TO 40 KNOTS. SEE REF B (WTPN32 PGTW 132100) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 22N 
138E, APPROXIMATELY 245 NM SOUTHWEST OF IWO TO. ANIMATED MULTISPECTRAL 
IMAGERY (MSI) DEPICTS A VERY COMPACT LOW-LEVEL CIRCULATION CENTER 
(LLCC) WITH FLARING CONVECTION OVER THE CIRCULATION. A 130102Z ASCAT-C 
PASS REVEALS 20-25 KNOTS WINDS AROUND THE BULK OF THE CIRCULATION, 
WITH SOME HIGHER WINDS FURTHER TO THE SOUTH IN THE MONSOONAL 
SOUTHWESTERLIES. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS 
FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10 TO 15KTS), WARM SEA 
SURFACE TEMPERATURES (29 TO 30 C), AND GOOD POLEWARD UPPER-LEVEL 
OUTFLOW. DETERMINISTIC MODELS DEPICT A CIRCULATION THAT MOVES 
GENERALLY NORTH-NORTHEAST BUT DOES NOT DEVELOP  INTO A TROPICAL 
CYCLONE. ENSEMBLE MODELS SHOW THE RAPID ATTAINMENT, BUT SHORT-LIVED 
DURATION, OF TROPICAL DEPRESSION STRENGTH AND A SIMILAR TRACK TO THE 
DETERMINISTIC MODELS OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 22 TO 24 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 IS UPGRADED TO 
HIGH. SEE REF C (WTPN21 PGTW 130600) 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: UPDATED PARA. 1.A.(2) WITH 13W FINAL 
WARNING INFORMATION.//
