1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):

   A. TROPICAL CYCLONE SUMMARY:

      (1) AT 23AUG26 0000Z, TYPHOON 17W (SAUDEL) WAS LOCATED NEAR

21.0N 142.3E, APPROXIMATELY 861 NM EAST- SOUTHEAST OF KADENA AB, AND

HAD TRACKED WEST-NORTHWESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS.

MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 110 KNOTS GUSTING TO

135 KNOTS. SEE REF A (WTPN31 PGTW 230300) FOR FURTHER DETAILS.

      (2) AT 23AUG26 0000Z, TROPICAL STORM 18W (NARRA) WAS LOCATED

NEAR 20.8N 107.9E, APPROXIMATELY 113 NM EAST OF HANOI, VIETNAM, AND

HAD TRACKED WEST-SOUTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS.

MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO

45 KNOTS. SEE REF B (WTPN32 PGTW 230300 COR) FOR FURTHER DETAILS.

      (3) AT 23AUG26 0000Z, TROPICAL DEPRESSION 19W (NINETEEN) WAS

LOCATED NEAR 12.9N 135.2E, APPROXIMATELY 266 NM NORTHWEST OF YAP, AND

HAD TRACKED NORTH- NORTHWESTWARD AT 03 KNOTS OVER THE PAST SIX HOURS.

MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO

40 KNOTS. SEE REF C (WTPN33 PGTW 230300) FOR FURTHER DETAILS.

      (4) NO OTHER TROPICAL CYCLONES.

   B. TROPICAL DISTURBANCE SUMMARY:

      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR

26.5N 123.7E IS NOW LOCATED NEAR 25.9N 122.4E, APPROXIMATELY 74 NM

NORTHEAST OF TAIPEI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)

DEPICTS A BROAD AND POORLY-DEFINED CIRCULATION THAT IS PARTIALLY

OBSCURED BY CONVECTION BUILDING IN THE SOUTHEASTERN PERIPHERY OF THE

CIRCULATION. A 230030 ASCAT-B PASS REVEALS AN ELONGATED CIRCULATION

WITH 25 TO 30 KNOT WINDS TO THE NORTH-NORTHEASTERN PERIPHERY OF THE

CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR

DEVELOPMENT WITH LOW TO MODERATE (15 TO 20 KTS) VERTICAL WIND SHEAR,

WARM SEA SURFACE TEMPERATURES (28 TO 29 C), AND GOOD EQUATORWARD

UPPER-LEVEL OUTFLOW. GLOBAL MODELS CONTINUE TO INDICATE THAT THE BROAD

CIRCULATION WILL STRUGGLE TO CONSOLIDATE INTO A TROPICAL CYCLONE.

ENSEMBLE MODELS ALSO STRUGGLE TO DEVELOP 94W AND SHOW A GENERALLY

WESTWARD TRACK. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 27 TO

32 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 999 MB.

THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE

WITHIN THE NEXT 24 HOURS REMAINS LOW.

      (2) 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.//
