DIFFICULT TO DISCERN ASH THROUGH 1715Z BUT
MULTISPECTRAL IMAGERY SUGGESTED A LARGE AREA OF
DIFFUSE REMNANT ASH AND GASES EXISTED IN THE
CENTRAL CARIBBEAN SEA.  THE HEIGHT OF THIS ASH WAS
ESTIMATED NEAR FL150.  ASH CONTINUES TO BE EMITTED
FROM THE VOLCANO AND AN ASH PLUME EXTENDED 76 NMI
TO THE NORTHWEST OF THE SUMMIT.   A PILOT REPORT
AT 1512Z INDICATED THIS ASH WAS BETWEEN FL030 AND
FL050 IN THE VICINITY OF ST. KITTS. ...TURK
