1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 09AUG26 1200Z, TROPICAL STORM 14W (CHAN-HOM) WAS LOCATED 
NEAR 32.3N 150.7E, APPROXIMATELY 577 NM EAST-SOUTHEAST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED NORTHWARD AT 01 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 
45 KNOTS. SEE REF A (WTPN33 PGTW 091500) FOR FURTHER DETAILS.
      (2) AT 09AUG26 1200Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 
27.9N 120.6E, APPROXIMATELY 175 NM NORTH-NORTHWEST OF TAIPEI, TAIWAN, 
AND HAD TRACKED WESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 KNOTS GUSTING TO 80 
KNOTS. SEE REF B (WTPN31 PGTW 091500) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (3) AT 09AUG26 1200Z, TROPICAL STORM 13W (PEILOU) WAS LOCATED 
NEAR 20.8N 144.0E, APPROXIMATELY 429 NM NORTH OF ANDERSEN AFB, AND HAD 
TRACKED EAST-SOUTHEASTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 
45 KNOTS. SEE REF C (WTPN32 PGTW 091500) FOR FURTHER DETAILS.
      (4) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
19.6N 150.5E IS NOW LOCATED NEAR 23.6N 158.9E, APPROXIMATELY 502 NM 
WEST-NORTHWEST OF WAKE ISLAND. ANIMATED MULTISPECTRAL IMAGERY (MSI) 
DEPICTS A DEVELOPED LOW-LEVEL CIRCULATION CENTER (LLCC), OBSCURED BY 
UPPER-LEVEL CONVECTION EMBEDDED WITHIN A LONGWAVE TROUGH. A PARTIAL 
082301Z ASCAT-C PASS REVEALED AN ELONGATED AND RELATIVELY WEAK 
CIRCULATION EMBEDDED WITHIN A BAND OF STRONG SOUTHWESTERLY MONSOONAL 
FLOW ON THE EASTERN FLANK OF A LARGE CYCLONIC GYRE. MAXIMUM WINDS IN 
THE ASCAT IMAGERY ARE 20-25 KNOTS IN THE EASTERN HEMISPHERE OF THE 
CIRCULATION. ENVIRONMENTAL ANALYSIS SHOWS FAVORABLE CONDITIONS FOR 
DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10 TO 15KTS), WARM SEA 
SURFACE TEMPERATURES (29 TO 30 C), AND GOOD POLEWARD OUTFLOW. 
DETERMINISTIC MODELS BRIEFLY DEVELOP 98W INTO A WEAK TROPICAL 
DEPRESSION THAT GENERALLY TRACKS NORTH-NORTHEASTWARD ALONG THE EASTERN 
PERIPHERY OF THE CYCLONIC GYRE PATTERN. FOR ENSEMBLE MODELS, ECENS 
INDICATES A HIGHER INTENSITY OF 98W AS OPPOSED TO GEFS MAINTAINING A 
LOWER CONFIDENCE AND INTENSITY. BOTH HOWEVER, AGREE UPON THE NORTH-
NORTHEAST TRACK OF 98W OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 17 TO 22 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 HIGH. SEE REF D (WTPN21 PGTW 090600) 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 12W FINAL 
WARNING INFORMATION.//
