REMARKS: MULTI-SPECTRAL IMAGERY SHOWS THE PLUME OF
ASH TO THE NW OF THE VOLCANO THOUGH HIGH LEVEL
CIRRUS IS BLOCKING MUCH OF THE VIEW NEAR THE
SUMMIT ITSELF.  THE HIGH LEVEL CLOUDS MAY BE
OBSCURRING ASH NEAR FL100 THAT WOULD BE MOVING TO
THE SSW...BUT CANNOT CONFIRM THIS.  ASH WILL BEGIN
TO SHIFT IN MOVEMENT FROM NW TO THE NE BY END OF
FORECAST PERIOD IN ADVANCE OF APPROACHING SHEAR
ZONE.  ...GALLINA
