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 33.0N 154.9E, APPROXIMATELY 793 NM EAST-SOUTHEAST OF MISAWA, 
JAPAN, AND HAD TRACKED WEST-NORTHWESTWARD AT 15 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF B (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 A (WTPN31 PGTW 081500) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 13W) PREVIOUSLY LOCATED NEAR 
22.1N 138.3E IS NOW LOCATED NEAR 22.7N 139.5E, APPROXIMATELY 167 NM 
SOUTHWEST OF IWO TO. ENHANCED INFRARED IMAGERY (EIR) DEPICTS A LOW-
LEVEL CIRCULATION CENTER (LLCC) OBSCURED BY CONVECTION. THE 
CIRCULATION IS CURRENTLY EMBEDDED WITHIN A TROUGH NEAR A COL-REGION 
ON THE FAR EASTERN FLANK OF THE EXPANSIVE CIRCULATION ASSOCIATED WITH 
TY 12W. A 081151Z ASCAT-B PASS REVEALS A CLOSED CIRCULATION WHICH IS 
PINCHING OFF FROM THE TROUGH, WITH HEIGHTENED WIND SPEEDS (25 TO 
30KTS) ON THE SOUTHERN PERIPHERY. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL SHEAR (5 TO 
10KTS), WARM SEA SURFACE TEMPERATURES (29 TO 30 C), AND GOOD EASTWARD 
UPPER-LEVEL OUTFLOW. DETERMINISTIC MODELS ALL SHOW FURTHER STEADY 
DEVELOPMENT OF 13W AS IT GETS PULLED EASTWARD ALONG THE SOUTHERN 
FLANK OF A PERSISTENT, LARGE CYCLONIC GYRE. ENSEMBLE MODELS ALSO 
AGREE ON ITS CONTINUED DEVELOPMENT ALONG WITH A GENERAL EASTWARD 
TRACK 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 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
MEDIUM.
      (2) THE AREA OF CONVECTION (INVEST 97) PREVIOUSLY LOCATED NEAR 
20.1N 108.2E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (3) 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 TINIAN. 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 IS UPGRADED TO 
MEDIUM.
      (4) 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: JUSTIFICATION FOR REISSUE: UPGRADED 
AREAS IN PARA 1.B.(1) AND1.B.(3) TO MEDIUM.//
