Potential Ash Hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift principally to the southeast and east this morning, shifting to the north and northwest this afternoon.

Recent observations: Clear skies afford excellent views of the volcano again this morning. Extrusion of the growing lava dome continues, accompanied by generally low levels of seismicity. Under current conditions, occasional rockfalls from the new dome remain probable, and they may generate plumes of dust and ash that rise above the crater rim.
