B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 7.1N 86.3E,
APPROXIMATELY 385 NM WEST OF COLOMBO, SRI LANKA. ANIMATED
MULTISPECTRAL IMAGERY REVEALS A BROAD AND ELONGATED LOW LEVEL
CIRCULATION CENTER (LLCC)WITH IMPROVING DEEP CONVECTION FORMING OVER
THE DISTURBANCE. ALSO A 1524Z ASCAT IMAGE SHOWS A DISORGANIZED LLCC
WITH 20KT WINDS ALONG THE NORTHERN PERIPHERY. THE DISTURBANCE IS
CURRENTLY LOCATED EQUATORWARD OF SUBTROPICAL RIDGE AXIS IN AN
ENVIRONMENT OF FAVORABLE DIVERGENCE ALOFT WITH LOW TO MODERATE (10-
20KT) VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
