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 91W) PREVIOUSLY LOCATED 
NEAR 6.7N 140.7E IS NOW LOCATED NEAR 7.3N 135.9E, APPROXIMATELY 78 
NM EAST OF PALAU, FSM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND 
A 160405Z AMSR2 89GHZ MICROWAVE PASS REVEALS CONSOLIDATING BANDING 
WITH FLARING CONVECTION IN THE EASTERN PERIPHERY WRAPPING INTO A LOW 
LEVEL CIRCULATION CENTER (LLCC). UPPER LEVEL ANALYSIS INDICATES 
INVEST 91W IS IN A FAVORABLE ENVIRONMENT FOR POTENTIAL TROPICAL 
DEVELOPMENT WITH POLEWARD OUTFLOW, LOW TO MODERATE (10-20KT) 
VERTICAL WIND SHEAR, AND WARM (29-30C) SEA SURFACE TEMPERATURES. 
GLOBAL MODELS ARE IN AGREEMENT THAT INVEST 91W WILL TRACK WEST-
NORTHWESTWARD AND STRENGTHEN TO WARNING STATUS WITHIN 48 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 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):
