1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 08AUG26 1200Z, TROPICAL STORM 14W (CHAN-HOM) WAS LOCATED 
NEAR 33.1N 153.2E, APPROXIMATELY 723 NM EAST-SOUTHEAST OF MISAWA, 
JAPAN, AND HAD TRACKED WESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS GUSTING TO 
50 KNOTS. SEE REF A (WTPN33 PGTW 081500) FOR FURTHER DETAILS.
      (2) AT 08AUG26 1200Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 
27.0N 124.8E, APPROXIMATELY 164 NM WEST OF KADENA AB, AND HAD TRACKED 
WEST- NORTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 KNOTS GUSTING TO 90 
KNOTS. SEE REF B (WTPN31 PGTW 081500) FOR FURTHER DETAILS.
      (3) 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 20.5N 152.5E, APPROXIMATELY 513 NM 
NORTHEAST OF TINAN. ENHANCED INFRARED IMAGERY (EIR) DEPICTS A STILL 
LOOSELY DEFINED BUT NOW FULLY DEVELOPED CLOSED CIRCULATION EMBEDDED 
WITHIN A BROAD TROUGH. A 081011Z ASCAT-B PASS REVEALS A STILL LOOSE 
BUT NOW CONSOLIDATED CIRCULATION, SHOWING 25 TO 30KTS ALONG THE 
SOUTHWESTERN PERIPHERY OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS 
REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND 
SHEAR (5 TO 10KTS), 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. ENSEMBLE 
MODELS DEPICT MORE SIGNIFICANT DEVELOPMENT AND A GENERAL NORTHEAST 
TRACK OF 98W OVER THE NEXT 24 TO 36 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 22 TO 27 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
      (2) THE AREA OF CONVECTION (REMNANTS 13W) PREVIOUSLY LOCATED 
NEAR 19.6N 150.5E IS NOW LOCATED NEAR 22.5N 140.9E, APPROXIMATELY 135 
NM SOUTH OF IWO TO. ANITMATED ENHANCED INFRARED SATELLITE IMAGERY 
(EIR) DEPICTS A CONCOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC) 
WITH FLARING CONVECTION IN THE SOUTH-SOUTHEASTERN PERIHPERY OF THE 
REMNANTS OF 13W. A 081153Z METOP-B ASCAT PASS REVEALS AN ASYMMMETRIC 
WIND FIELD WITH 20-25 KNOT WINDS TO THE SOUTH BEGINNING TO WRAP MORE 
INTO THE CENTER. ENVIRONMENTAL ANALYSIS INDICATES THAT 13W IS IN A 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT DUE TO VERY WARM (30-31 C) SEA 
SURFACE TEMPERATURES, LOW TO MODERATE (15-20 KTS) VERTICAL WIND 
SHEAR, AND GOOD EQUATERWARD OUTFLOW ALOFT. THE GFS DETERMINISTIC IS 
THE PRIMARY MODEL INDICATING DEVELOPMENT OVER THE NEXT 24 HOURS WITH 
OTHER GLOAL MODELS BEGINNING TO SHOW MARGINAL DEVELOPMENT. ENSEMBLE 
GUIDANCE ARE IN STRONG AGREEMENT WITH 13W TRACKING IN A GENERAL 
EASTWARD DIRECTION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
22 TO 27 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
998 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 081930) 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 REMNANTS 13W TO HIGH IN PARA
