(3) AN AREA OF CONVECTION HAS PERSISTED NEAR 16.7N 135.5E,
APPROXIMATELY 460 NM NORTH-NORTHWEST OF YAP. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS LOW LEVEL CONVECTIVE BANDING WRAPPING INTO
DEVELOPING LLCC. UPPER LEVEL ANALYSIS REVEALS THAT THE LLCC IS
LOCATED BENEATH AN ANTICYCLONE WITH STRONG DIFFLUENT FLOW ALOFT AND
LOW VERTICAL WIND SHEAR. 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.
