1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 22AUG26 0000Z, TYPHOON 17W (SAUDEL) WAS LOCATED NEAR
17.9N 146.5E, APPROXIMATELY 167 NM NORTH-NORTHEAST OF SAIPAN, AND HAD
TRACKED NORTHWESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 85 KNOTS GUSTING TO 105
KNOTS. SEE REF A (WTPN31 PGTW 220300) FOR FURTHER DETAILS.
      (2) AT 22AUG26 0000Z, TROPICAL STORM 18W (EIGHTEEN) WAS LOCATED
NEAR 21.1N 108.7E, APPROXIMATELY 157 NM EAST OF HANOI, VIETNAM, AND
HAD TRACKED NORTHWESTWARD AT 01 KNOTS OVER THE PAST SIX HOURS.
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO
45 KNOTS. SEE REF B (WTPN32 PGTW 220300) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR
10.1N 138.1E IS NOW LOCATED NEAR 26.5N 123.7E, APPROXIMATELY 219 NM
WEST OF KADENA. 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. 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 1005 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
      (2) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR
10.1N 138.1E IS NOW LOCATED NEAR 10.2N 136.6E, APPROXIMATELY 99 NM
WEST-NORTHWEST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
DEPICTS A BROAD, SLOWLY CONSOLIDATING LOW LEVEL CIRCULATION (LLC)
WITH DEEP, PERSISTENT FLARING CONVECTION OVER THE WESTERN PERIPHERY.
ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (VWS) OF 15-20 KNOTS, GOOD
UPPER-LEVEL OUTFLOW, AND WARM SEA SURFACE TEMPERATURES (SST) OF 29-30
C. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS REMAIN IN STRONG
AGREEMENT, INDICATING A BRIEF WINDOW FOR CYCLOGENESIS AS INVEST 97W
TRACKS GRADUALLY NORTHWARD OVER THE NEXT 48 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.
      (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 AREA IN PARA 1.B.(2) TO
MEDIUM//
