1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
10.3N 136.8E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
     C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 09W) PREVIOUSLY LOCATED NEAR 
34.3N 117.8E IS NOW LOCATED NEAR 35.7N 119.9E, APPROXIMATELY 364 NM 
WEST-SOUTHWEST OF SEOUL, SOUTH KOREA. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL DEPRESSION, GENERALLY CHARACTERIZED AS 
HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED 
ENHANCED INFRARED SATELLITE IMAGERY (EIR) DEPICTS A WEAK, BROAD 
ROTATION MOVING EAST-NORTHEASTWARD OVER ALONG THE SOUTHERN COAST OF 
THE QINGDAO PENINSULA AND MOVING INTO THE YELLOW SEA; THE REMNANTS OF 
09W IS FORECAST TO CONTINUE MOVING RAPIDLY EAST-NORTHEASTWARD WHILE 
QUICKLY TRANSITIONING TO AN EXTRATROPICAL CYCLONE AS IT PASSES OVER 
THE NORTHERN KOREAN PENINSULA.  ENVIRONMENTAL ANALYSIS OF THE AREA 
INDICATES UNFAVORABLE CONDITIONS FOR TROPICAL TRANSITION. THE SYSTEM 
LIES UNDER A 500MB LOW-HEIGHT CENTER AND STACKS BACK TO A STRONG 200MB 
TROF CURRENTLY OVER NORTHERN CHINA, WHICH IS INDUCING LOW TO MODERATE 
VERTICAL WIND SHEAR (15-20 KTS) AND STRONG POLEWARD OUTFLOW ALOFT, 
WHICH IS HELPING TO MAINTAIN A SMALL REGION OF SHALLOW CONVECTION NEAR 
THE CORE OF THE SYSTEM. SEA SURFACE TEMPERATURES ARE VERY COOL (22-25 
C), PROVIDING MINIMAL THERMODYNAMIC SUPPORT FOR THE SYSTEM. GLOBAL 
MODELS ARE IN AGREEMENT THAT THE REMNANTS OF 09W WILL MOVE NORTH-
NORTHEAST WHILE MAINTAINING A BROAD AND ASYMMETRIC WIND FIELD. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 993 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: DISSIPATED AREA IN PARA. 1.B.(1).//
