1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 01SEP24 1800Z, TROPICAL STORM 12W (YAGI) WAS LOCATED NEAR 
14.6N 123.2E, APPROXIMATELY 128 NM EAST OF MANILA, PHILIPPINES, AND HAD 
TRACKED WEST-NORTHWESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 KNOTS. 
SEE REF A (WTPN31 PGTW 012100) FOR FURTHER DETAILS.
      (2) AT 01SEP24 1200Z, TROPICAL DEPRESSION 11W (SHANSHAN) WAS 
LOCATED NEAR 34.9N 136.6E, APPROXIMATELY 154 NM WEST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED NORTH-NORTHWESTWARD AT 11 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 20 KNOTS 
GUSTING TO 30 KNOTS. SEE REF B (WTPN32 PGTW 011500) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 01C) HAS PERSISTED NEAR 26.1N 
179.5E, APPROXIMATELY 206 NM SOUTHWEST OF MIDWAY. THIS SYSTEM IS 
CLASSIFIED AS A SUBTROPICAL DEPRESSION, GENERALLY CHARACTERIZED AS 
HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED 
ENHANCED INFRARED SATELLITE IMAGERY AND A 012130Z ASCAT METOP-C 25KM 
IMAGE DEPICTS A WEAK ASYMMETRIC SYSTEM WITH A LARGE RADIUS OF MAX 
WINDS. ENVIRONMENTAL ANALYSIS REVEALS MARGINALLY UNFAVORABLE CONDITIONS 
FOR TROPICAL TRANSITION WITH HIGH (27-28 C) SEA SURFACE TEMPERATURES 
AND LOW TO MODERATE (15 -20 KTS) VERTICAL WINDSHEAR, OFFSET BY 
SIGNIFICANT DRY AIR ENTRAINMENT AND CONVERGENCE ALOFT. GLOBAL MODELS 
ARE IN AGREEMENT OF A TRACK NORTHWARD FOLLOWED BY A QUICK DISSIPATION 
OF THE SYSTEM. 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 IS 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: ADDED AREA IN 1.C.(1) AS A LOW.//
