1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 91W) HAS PERSISTED NEAR 30.8N 
153.8E, APPROXIMATELY 764 NM EAST-SOUTHEAST OF TOKYO. THE SYSTEM IS 
CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY CHARCTERIZED 
AS HAVING BOTH TROPICAL AND MIDLATTITUDE CYCLONE FEATURES. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS INVEST 91W WITH A FULLY 
EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) AND DEEP CONVECTION BEING 
SHEARED TO THE EAST-SOUTHEAST. ENVIRONMENTAL ANALYSIS REVEALS MARGINAL 
CONDITIONS FOR TROPICAL DEVELOPMENT WITH MODERATE VERTICAL WIND SHEAR 
(20-25 KNOTS), MODERATE POLEWARD OUTFLOW, AND WARM (27-28 C) SEA 
SURFACE TEMPERATURES. DETERMINISTIC MODELS DEPICT INVEST 91W WITH AN 
ASYMMETRIC WIND FIELD THAT EXPANDS AND ELONGATES WITHIN A 12-36 HOUR 
PERIOD WHILE TRANSITING POLEWARD INTO THE MIDLATITUDE WESTERLIES. THE 
SYSTEM IS EXPECTED TO RETAIN SUBTROPICAL CYCLONE CHARACTERISTICS DURING 
THIS TIME BEFORE BECOMING FULLY EMBEDDED IN THE MIDLATITUDE BAROCLINIC 
ZONE AND BECOMING EXTRATROPICAL. FOR HAZARDS AND WARNINGS, REFERNCE THE 
FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO 
LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 23 TO 28 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 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 LOW AREA IN PARA 1.C.(1)//
