REMARKS: A NARROW BUT MORE INTENSE PLUME IS MOVING
NW FROM THE SUMMIT JUST SOUTH OF NEVIS.  PILOT
REPORTS HELP TO INCREASE HEIGHT TO FL090...WHICH
COULD EXPLAIN SOME ASH BEGINNING TO MOVE
W...AFFECTED BY MORE EASTERLY FLOW ALOFT.  STILL
THE DENSITY OF THE EMISSIONS FROM THE VOCLANO OVER
THE NEXT 12HRS WILL DICTATE IF THE ASH WILL REACH
THE VIRGIN ISLANDS. SO WILL BE CONSERVATIVE AND
INCLUDE THEM IN THE FORECAST AREAS THOUGH THERE IS
NO WAY TO FORECAST THE VOLCANO EMISSIONS.
