對流仍屬散亂狀
AN AREA OF CONVECTION HAS PERSISTED NEAR 6.5N 159.1E,
APPROXIMATELY 60 NM EAST-SOUTHEAST OF POHNPEI. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD AND ELONGATED LLCC
WITH BUILDING CONVECTION ALONG THE SOUTHWESTERN PERIPHERY. A 252331Z
ASCAT PASS REVEALS ENHANCED WESTERLY FLOW TO THE SOUTH OF BROAD
TROUGHING, WHILE OBSERVATIONS FROM POHNPEI SHOW VARIABLE WEST TO
SOUTHWEST WINDS RANGING FROM 10 TO 15 KNOTS. UPPER LEVEL ANALYSIS
SHOWS A CONDUCIVE ENVIRONMENT WITH WESTERLY DIVERGENT OUTFLOW AND
LOW TO MODERATE (10 TO 15 KNOTS) VERTICAL WIND SHEAR. DYNAMIC MODEL
GUIDANCE INDICATES DEVELOPMENT FROM THIS REGION IN THE NEXT 48 TO 72
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.
