1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 31AUG24 0600Z, TROPICAL DEPRESSION 11W (SHANSHAN) WAS LOCATED 
NEAR 33.6N 136.8E, APPROXIMATELY 176 NM SOUTHWEST OF YOKOSUKA, JAPAN, AND 
HAD TRACKED EASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 35 KNOTS. 
SEE REF A (WTPN32 PGTW 310900) FOR THE FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
10.7N 131.1E IS NOW LOCATED NEAR 11.9N 126.4E, APPROXIMATELY 354 NM EAST-
SOUTHEAST OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
DEPICT A CONSOLIDATING AREA OF BROAD CYCLONIC TURNING. A 311647Z AMSR2 GW1 
89 GHZ MICROWAVE IMAGE SHOWS A LARGE AREA OF DEEP CONVECTION TO THE WEST 
OF THE CIRCULATION CENTER. UPPER-LEVEL CONDITIONS FOR 92W ARE FAVORABLE 
WITH GOOD POLEWARD AND EQUATORWARD DIVERGENCE ALOFT, LOW TO MODERATE (10-
15 KNOTS) VERTICAL WIND SHEAR, AND WARM (29-30 C) SEA SURFACE 
TEMPERATURES. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS SHOW A WEST 
NORTHWESTWARD TRACK AS THE SYSTEM TRANSITS UP THE EASTERN COAST OF THE 
PHILIPPINES, WITH ECMWF AND GFS AGGRESSIVELY FAVORING DEVELOPMENT OVER THE 
NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 
20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE 
NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO MEDIUM.//
