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 94W) PREVIOUSLY LOCATED 
NEAR 6.0N 153.7E IS NOW LOCATED NEAR 8.5N 151.3E, APPROXIMATELY 77 
NM NORTH-NORTHWEST OF CHUUK. ANIMATED ENHANCED MULTISPECTRAL 
SATELLITE IMAGERY (MSI) DEPICTS A DISORGANIZED AREA OF FRAGMENTED 
CONVECTION. A PARTIAL 200252Z AMSR2 89GHZ MICROWAVE PASS SHOWS A 
SHARP EASTERLY WAVE OR A POSSIBLE WEAK LOW LEVEL CIRCULATION (LLC) 
WITH CYCLING CONVECTION TO THE NORTHEAST. PREVIOUS SCATTEROMETER 
DATA INDICATES AN ASYMMETRIC WIND FIELD, WITH LIGHT WINDS IN THE 
SOUTHERN SEMICIRCLE AND STRONGER (15-20 KT) WINDS ACROSS THE 
NORTHEASTERN QUADRANT IN THE GRADIENT FLOW. INVEST 94W IS IN A 
FAVORABLE ENVIRONMENT FOR TROPICAL DEVELOPMENT WITH FAIR EQUATORWARD 
OUTFLOW, LOW (5-10 KTS) VERTICAL WIND SHEAR, AND WARM (29-30 
CELSIUS) SEA SURFACE TEMPERATURES. NUMERICAL MODELS ARE IN GOOD 
AGREEMENT THAT INVEST 94W WILL CONTINUE TO TRACK WEST-NORTHWESTWARD 
AS IT SLOWLY CONSOLIDATES OVER THE NEXT 24-36 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR 
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS REMAINS MEDIUM.
      (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.//
