1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 20AUG26 1800Z, TROPICAL STORM 17W (SAUDEL) WAS LOCATED 
NEAR 13.7N 149.6E, APPROXIMATELY 238 NM EAST-SOUTHEAST OF SAIPAN, AND 
HAD TRACKED NORTHWESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS GUSTING TO 50 
KNOTS. SEE REF A (WTPN31 PGTW 202100) FOR FURTHER DETAILS.
      (2) AT 20AUG26 1800Z, TROPICAL DEPRESSION 18W (EIGHTEEN) WAS 
LOCATED NEAR 20.1N 108.4E, APPROXIMATELY 150 NM EAST-SOUTHEAST OF 
HANOI, VIETNAM, AND HAD TRACKED WEST-NORTHWESTWARD AT 08 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
25 KNOTS GUSTING TO 35 KNOTS. SEE REF B (WTPN32 PGTW 202100) FOR 
FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
23.0N 126.7E IS NOW LOCATED NEAR 23.9N 127.1E, APPROXIMATELY 151 NM 
SOUTH-SOUTHWEST 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 CENTER PARTIALLY OBSCURED BY DENSE CONVECTION 
BUILDING TO THE SOUTH-SOUTHEASTERN PERIPHERY. 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 IS UNLIKELY 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 18 TO 23 
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) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 
19.5N 111.8E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 1.A.(2) FOR FURTHER DETAILS.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 
33.2N 164.1E IS NOW LOCATED NEAR 35.6N 160.9E, APPROXIMATELY 969 NM 
EAST-SOUTHEAST 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 DEEP ASSOCIATED CONVECTION OVER 
THE WEST-NORTHWESTERN PERIPHERY. A POTENT UPPER-LEVEL LOW PRESENTLY 
INHIBITS CONVECTIVE ACTIVITY OVER THE CENTER, AND PLENTY OF DRY AIR IS 
WRAPPING INTO THE CIRCULATION. DETERMINISTIC MODELS SHOW 96W 
TRANSITING NORTHWESTWARD AND DIMINISHING AS THE UPPER-LEVEL LOW 
WEAKENS AND THE ENVIRONMENTAL CONDITIONS BECOME MORE HOSTILE, WITH 
TRANSITION INTO A TROPICAL CYCLONE BEING UNLIKELY. 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 28 TO 33 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 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: UPGRADED AREA IN PARA 1.B.(2) TO WARNING 
STATUS.//
