REMARKS: A MODERATELY DENSE PLUME OF ASH IS NW OF
THE VOLCANO. HOWEVER WINDS ARE SHIFTING FROM THE
EASTERLIES TOWARD SOUTHERLIES WITH THE APPROACH OF
A WEAK BOUNDARY.  THIS WILL LEAD TO EVENTUAL
VEERING OF THE ASH TOWARD THE N THEN TO THE NE BY
THE END OF THE FORECAST PERIOD.  VISIBLE IMAGERY
SHOWS A VERY EXTENSIVE VOG AREA  AS IT IS SUCKED
NORTHEASTWARD AHEAD OF THE BOUNDARY.  ...GALLINA
