1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 21AUG26 0000Z, TROPICAL STORM 17W (SAUDEL) WAS LOCATED 
NEAR 14.7N 149.0E, APPROXIMATELY 188 NM EAST OF SAIPAN, AND HAD 
TRACKED NORTH-NORTHWESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 
55 KNOTS. SEE REF A (WTPN31 PGTW 210300) FOR FURTHER DETAILS.
      (2) AT 21AUG26 0000Z, TROPICAL DEPRESSION 18W (EIGHTEEN) WAS 
LOCATED NEAR 20.2N 108.6E, APPROXIMATELY 159 NM EAST-SOUTHEAST OF 
HANOI, VIETNAM, AND HAD TRACKED EAST-NORTHEASTWARD AT 02 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
30 KNOTS GUSTING TO 40 KNOTS. SEE REF B (WTPN32 PGTW 210300) FOR 
FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR 26.1N 
125.1E, APPROXIMATELY 144 NM WEST OF KADENA AIR FORCE BASE. THE 
SYSTEM IS CURRENTLY CLASSIFIED AS A MONSOON DEPRESSION, GENERALLY 
CHARACTERIZED AS A LARGE CYCLONIC CIRCULATION, GREATER THAN 600 NM 
DIAMETER, WITH ENHANCED WINDS OVER THE SOUTHEASTERN PERIPHERY AND A 
WEAK CORE OF LIGHT WINDS. ANIMATED ENHANCED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS A BROAD CIRCULATION PARTIALLY OBSCURED BY DENSE 
CONVECTION BUILDING IN THE SOUTH-SOUTHEASTERN PERIPHERY. A 210135Z 
METOP-C ASCAT PASS REVEALED 20-25 KTS WINDS DISPLACED APPROXIMATELY 
125 NAUTICAL MILES EAST OF THE ANALYZED POSITION OF THE CENTER. 
ENVIRONMENTAL ANALYSIS REVEALS MOSTLY CONDUCIVE CONDITIONS FOR 
DEVELOPMENT WITH LOW TO MODERATE (15 TO 20 KTS) VERTICAL WIND SHEAR, 
MODERATE UPPER-LEVEL EQUATORWARD OUTFLOW, AND WARM (28-29C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS INDICATE THAT THE BROAD 
CIRCULATION WILL STRUGGLE TO CONSOLIDATE INTO A TROPICAL CYCLONE IN 
THE NEXT 24-36 HOURS. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET 
WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO 
LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 23 TO 28 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 LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 
35.6N 160.9E IS NOW LOCATED NEAR 38.7N 158.7E, APPROXIMATELY 809 NM 
EAST OF MISAWA, JAPAN. THE SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL 
AND MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED MULTISPECTRAL 
SATELLITE IMAGERY (MSI) DEPICTS INVEST 96W WITH A FULLY EXPOSED LOW-
LEVEL CIRCULATION CENTER (LLCC) AND ASSOCIATED CONVECTION OVER THE 
NORTHERN PERIPHERY. A POTENT UPPER-LEVEL LOW PRESENTLY INHIBITS 
CONVECTIVE ACTIVITY OVER THE CENTER, AND PLENTY OF DRY AIR IS 
WRAPPING INTO THE CIRCULATION. A 202350 METOP-C ASCAT PASS REVEALED 
AN ASYMMETRIC, ALMOST FRONT-LIKE, WIND FIELD WITH MAXIMUM 30-35 KT 
WINDS WITHIN THE SOUTHEASTERN QUADRANT. ENVIRONMENTAL CONDITIONS 
AROUND THIS SYSTEM REMAIN UNFAVORABLE FOR DEVELOPMENT INTO A TROPICAL 
CYCLONE DUE TO THE COOL SEA SURFACE TEMPERATURES, SUBSIDENCE INDUCED 
BY THE UPPER-LEVEL LOW, AND THE SURROUNDING DRY AIR. DETERMINISTIC 
MODELS SHOW 96W TRANSITING NORTHEASTWARD AND DIMINISHING AS THE 
UPPER-LEVEL LOW WEAKENS AND THE ENVIRONMENTAL CONDITIONS BECOME MORE 
HOSTILE WITH TIME. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET 
WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO 
LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 33 TO 38 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
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).//
