1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 30JUL25 1200Z, TROPICAL STORM 12W (KROSA) WAS LOCATED 
NEAR 29.0N 143.2E, APPROXIMATELY 126 NM NORTH-NORTHEAST OF CHICHI 
JIMA, AND HAD TRACKED NORTHWESTWARD AT 01 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS 
GUSTING TO 50 KNOTS. SEE REF A (WTPN31 PGTW 301500) FOR FURTHER 
DETAILS.
      (2) AT 30JUL25 1200Z, TROPICAL STORM 11W (CO-MAY) WAS LOCATED 
NEAR 31.2N 121.4E, APPROXIMATELY 5 NM WEST OF SHANGHAI, CHINA, AND HAD 
TRACKED NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS.3 ANIMATED 
ENHANCED INFRARED IMAGERY (EIR) REVEALS THE BROAD AND RAGGED 
CIRCULATION OF TROPICAL STORM (TS) 11W DEGRADING OVER THE COAST. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 
45 KNOTS. SEE REF B (WTPN33 PGTW 301500) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:NONE
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
34.2N 151.4E IS NOW LOCATED NEAR 35.6N 155.7E, APPROXIMATELY 739 NM 
EAST-SOUTHEAST OF MISAWA. THE SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL 
AND MIDLATITUDE CYCLONE FEATURES. ANIMATED INHANCED INFRARED SATELLITE 
IMAGERY DEPICTS A WEAK LLCC ON THE SOUTHEASTERN FLANK OF AN UPPERLEVEL 
TROUGH WHILE BEING PARTIALLY EXPOSED ON THE WESTERN SEMICIRCLE. A 
300318Z ATMS 88.2GHZ IMAGE DEPICTS THE SYSTEM WITH A DEEPER CONVECTIVE 
CLOUD SYSTEM ON THE EASTERN SIDE WITH LITTLE TO NO CONVECTION ON THE 
OPPPOSITE SIDE. ENVIRONMENTAL ANALYSIS REVEALS UNFAVORABLE CONDITIONS 
FOR TROPICAL TRANSITION DEFINED BY A DEEP LAYER OF DRY AIR BEING 
ADVECTED OVER THE LOW LEVEL CIRCULATION AND HIGH (30 KNOTS) WESTERLY 
VERTICAL WIND SHEAR ASSOCIATED WITH AN APPROACHING LONGWAVE TROUGH. 
FURTHERMORE, THE SYSTEM IS FAST APPROACHING WATERS NOT CONDUCIVE FOR 
TROPICAL DEVELOPMENT (COOLER THAN 26C). GLOBAL DETERMINISTIC MODELS 
ARE IN AGREEMENT ON A NORTHEASTWARD TRACK WITH AN ASYMMETRIC WIND 
FIELD OVER THE NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1000 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.
3. JUSTIFICATION FOR REISSUE: UPDATED PARA 1.A.(2) WITH 11W FINAL 
WARNING INFORMATION.//
