1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 12AUG24 0600Z, TROPICAL STORM 06W (MARIA) WAS LOCATED 
NEAR 39.8N 141.0E, APPROXIMATELY 37 NM SOUTH-SOUTHWEST OF MISAWA, 
JAPAN, AND HAD TRACKED NORTHWESTWARD AT 10 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS 
GUSTING TO 55 KNOTS. SEE REF A (WTPN31 PGTW 120900) FOR FURTHER 
DETAILS.
      (2) AT 12AUG24 0600Z, TROPICAL STORM 07W (SON-TINH) WAS LOCATED 
NEAR 32.4N 151.5E, APPROXIMATELY 613 NM EAST-SOUTHEAST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED NORTHWESTWARD AT 18 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS 
GUSTING TO 50 KNOTS. SEE REF B (WTPN32 PGTW 120900) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
21.9N 135.9E IS NOW LOCATED NEAR 23.0N 136.3E APPROXIMATELY 507 NM 
EAST-SOUTHEAST OF KADENA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
AND A 120404Z ASMR2 89GHZ MICROWAVE IMAGE DEPICT A DEEPENING AREA OF 
CONVECTION WITH FORMATIVE BANDING IN THE NORTHERN PERIPHERY OF THE 
RAPIDLY CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC). 
ENVIRONMENTAL ANALYSIS INDICATES A FAVORABLE ENVINROMENT FOR 
DEVELOPMENT WITH STRONG POLEWARD OUTFLOW, ENHANCED BY A TUTT-CELL 
SITUATED TO THE NORTHWEST, LOW VERTICAL WIND SHEAR (10-15KTS), AND 
VERY WARM (30-32C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN 
AGREEMENT THAT 91W WILL GRADUALLY INTENSIFY AND CONTINUE TO TRACK 
NORTHWARD TOWARD MAINLAND JAPAN OVER THE NEXT 48 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 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 IS UPGRADED TO HIGH. SEE REF C (WTPN21 PGTW 120700) FOR FURTHER 
DETAILS.
      (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.(2) TO 
WARNING STATUS. UPGRADED AREA IN 1.B.(1) TO HIGH.//
