REMARKS: SATELLITE IMAGERY AT 10/1802Z CONTINUES
TO SHOW A LARGE ASH PLUME MOVING NW-NNW FROM THE
VOLCANO.  THE ASH PLUME IS ESTIMATED TO FL140.  
RECENT PGUM SOUNDING AT 12Z AND THE 18Z GFS
FORECAST MODEL WINDS ARE NOT SHOWING A NW-LY
COMPONENT SO THE CONFIDENCE IN ASH HEIGHT IS LOW. 
THE SECOND ASH PLUME HEADING WEST FROM THE SUMMIT
IS MOVING AT A LITTLE BIT FASTER SPEED OF 10-15
KNOTS AND IS ESTIMATED TO FL100.  WE WILL CONTINUE
TO CLOSELY MONITOR. ...KIBLER
