B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 12.1N 168.7E,
APPROXIMATELY 215 NM NORTH-NORTHEAST OF KWAJALEIN ATOLL. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A SMALL, SYMMETRIC AREA
OF DEEP CONVECTION PERSISTING OVER A BROAD LOW-LEVEL CIRCULATION
CENTER (LLCC). A 101031Z METOP-B 89GHZ IMAGE SHOWS WEAK, FORMATIVE
CONVECTIVE BANDING WRAPPING INTO THE LLCC. A 101030Z ASCAT IMAGE
SHOWS A BROAD CIRCULATION ASSOCIATED WITH A STRONG WESTERLY WIND
BURST OF 15 TO 20 KNOTS. SURFACE WIND OBSERVATIONS FROM KWAJALEIN
SHOW 10 TO 15 KNOT SUSTAINED WESTERLY WINDS WITH GUSTS AS HIGH AS
25 TO 30 KNOTS. UPPER-LEVEL ANALYSIS DEPICTS BROAD DIFFLUENCE
ENHANCED BY A TUTT CELL POSITIONED TO THE NORTH NEAR 21N 167E.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 IS LOW.
