Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds that rise above the crater rim today would drift to the southwest.

Recent observations: It is a beautiful spring day in southwest Washington and Mt. Saint Helens is clearly visible in all its glory. Real-time seismic and ground deformation instruments located in the crater and around the mountain indicate that new dome growth has continued over the last 24 hours in a relatively quiet and uneventful fashion, with frequent very small earthquakes and slow but steady westward expansion of the extrusion at approximately 1 meter per day.
