1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR 
5.0N 139.7E IS NOW LOCATED NEAR 5.4N 140.2E, APPROXIMATELY 272 NM SOUTH-
SOUTHEAST OF YAP. THE 06000Z POSITION HAS BEEN UPDATED BASED ON A 
REANALYSIS OF AVAILABLE SATELLITE DATA, AND RELOCATED APPROXIMATELY 180NM 
EAST-SOUTHEAST OF THE PREVIOUSLY ASSESSED 060000Z POSITION. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY DEPICTS PERSISTENT FLARING CONVECTION 
OVER THE STILL DISORGANIZED LOW LEVEL CIRCULATION (LLC). A 060101Z ASCAT 
METOP-B SCATTEROMETER PARTIAL PASS REVEALED THE WESTERN SIDE OF 90W TO 
HAVE A CONSISTENT WIND FIELD OF 10-15KTS FLOWING INTO THE LLC WITH FEW 
SMALL AREAS OF 20KTS. ENVIRONMENTAL ANALYSIS REVEALS A MARGINALLY 
FAVORABLE ENVIRONMENT WITH DIFFLUENT WESTERLY OUTFLOW, LOW TO MODERATE 
(10-15KTS) VERTICAL WIND SHEAR, AND VERY WARM (31-32C) SSTS. GLOBAL 
MODELS ARE IN AGREEMENT THAT 90W WILL CONTINUE ON A NORTHERLY TRACK 
TOWARDS YAP THEN A NORTHWESTWARD TURN TOWARDS THE PHILIPPINES AND THERE 
IT WILL CONTINUE ON A SLOW AND STEADY TRACK WITH GRADUAL INTENSIFICATION. 
THIS IS ALSO IN LINE WITH AN MJO SIGNAL EMERGING OVER THE MARITIME 
CONTINENT AND MAKING ITS WAY INTO THE WESTERN PACIFIC, THUS AIDING THE 
SYSTEM IN GAINING STRONGER WESTERLY WINDS WHICH WILL ASSIST IT IN 
BECOMING MORE ORGANIZED.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
1006 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: UPDATED 0000Z POSITION INFORMATION FOR 
INVEST 90W.//
