1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 02SEP24 0000Z, TROPICAL STORM 12W (YAGI) WAS LOCATED NEAR 
15.2N 122.6E, APPROXIMATELY 100 NM EAST-NORTHEAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED NORTHWESTWARD AT 06 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS 
GUSTING TO 50 KNOTS. SEE REF A (WTPN31 PGTW 020300) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 01C) PREVIOUSLY LOCATED NEAR 
26.1N 179.5E IS NOW LOCATED NEAR 25.0N 178.6E, APPROXIMATELY 289 NM 
SOUTHWEST OF MIDWAY ISLAND. THIS SYSTEM IS CLASSIFIED AS A SUBTROPICAL 
DEPRESSION, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND 
MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY DEPICTS A HIGHLY ASYMMETRIC CONVECTIVE STRUCTURE, WITH 
CONVECTIVE BANDING WRAPPING INTO A BROAD CENTER. A 020141Z ATMS 88.2 
GHZ MICROWAVE IMAGE REVEALS FRAGMENTED BANDS DISPLACED OVER THE 
EASTERN SEMICIRCLE, WITH A WEAK, BROAD LOW-LEVEL CIRCULATION. A 
012130Z ASCAT-C IMAGE REVEALS AN ELONGATED CIRCULATION, WITH A WEAK 
CORE AND MAXIMUM WINDS DISPLACED OVER 90NM TO THE NORTH. THE SYSTEM IS 
LOCATED UNDER A DEEP SUBTROPICAL TROUGH, WITH LOW TO MODERATE (15 TO 
20 KNOTS) VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1008 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.//
