1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 29AUG26 0000Z, TYPHOON 20W (BANG-LANG) WAS LOCATED NEAR 
22.2N 167.8E, APPROXIMATELY 187 NM NORTH-NORTHEAST OF WAKE ISLAND, AND 
HAD TRACKED NORTH-NORTHEASTWARD AT 19 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 KNOTS GUSTING TO 
80 KNOTS. SEE REF A (WTPN33 PGTW 290300) FOR FURTHER DETAILS.
      (2) AT 29AUG26 0000Z, TROPICAL STORM 21W (ETAU) WAS LOCATED NEAR 
26.4N 165.8E, APPROXIMATELY 428 NM NORTH OF WAKE ISLAND, AND HAD 
TRACKED NORTHWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF B (WTPN32 PGTW 290300) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (SS 01C) PREVIOUSLY LOCATED NEAR 
38.5N 179.8E IS NOW LOCATED NEAR 38.5N 178.8E, APPROXIMATELY 635 NM 
NORTH-NORTHWEST OF MIDWAY ATOLL. THE SYSTEM IS CURRENTLY CLASSIFIED AS 
A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL 
AND MIDLATITUDE CYCLONE FEATURES. MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS A BROAD BUT DEFINED LOW-LEVEL CIRCULATION CENTER DEVOID 
OF CONVECTION. ENVIRONMENTAL ANALYSIS DEPICTS A HIGHLY UNFAVORABLE 
AREA FOR DEVELOPMENT WITH HIGH VWS (50 KTS), DRY SURROUNDING AIR, AND 
COOL SEA SURFACE TEMPERATURES (23-25 C). ENSEMBLE AND DETERMINISTIC 
MODELS ARE IN AGREEMENT FOR A GRADUAL DECAY OVER THE NEXT 48 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 32 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.//
