RMKS/
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 
4.7N 136.3E IS NOW LOCATED NEAR 5.2N 136.9E, APPROXIMATELY 186 NM 
SOUTHEAST OF PALAU. 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.//
