1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR 
21.0N 140.5E, APPROXIMATELY 112 NM EAST-SOUTHEAST OF KADENA AB, 
JAPAN. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A 
BROAD, DISORGANIZED AREA OF CONVECTION PARTIALLY OBSCURING A LOW 
LEVEL CIRCULATION CENTER. FORMATIVE BANDING HAS IMPROVED OVER THE 
PAST 24 HOURS AS THE CONVECTION HAS IMPROVED AND CONTINUED TO 
BUILD. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED 
ON A 030658Z SSMIS 91GHZ IMAGE. A  030040Z ASCAT-C PASS FURTHER 
DEPICTS A VERY BROAD WIND FIELD IN EXCESS OF 100 NM DIAMETER. THE 
ENVIRONMENT IS FAVORABLE FOR DEVELOPMENT WITH LOW (10-15 KTS) 
VERTICAL WIND SHEAR, VERY WARM (30-31 CELSIUS) SEA SURFACE 
TEMPERATURES AND WELL ESTABLISHED POLEWARD AND EQUATORWARD OUTFLOW 
ALOFT. NUMERICAL MODELS ARE IN FAIR AGREEMENT THAT THE SYSTEM WILL 
CONTINUE TO SLOWLY CONSOLIDATE OVER THE NEXT 24 HOURS AS IS TRACKS 
GENERALLY NORTHWEST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 
NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (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: ADDED AREA IN PARA 1. B. (1) AS LOW.//
