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 west to southwest.

Recent observations: The eruption continues, as determined chiefly by low levels of seismicity that have characterized the past few months of lava dome growth. Dust plumes from rockfall in the crater have left dark patches on snow on the flanks of the volcano. There has been no explosive activity. Seismometers in and near the crater recorded signals last Friday evening suggestive of a small flood or lahar, perhaps originating from the crater glacier. Field crews today will look for evidence of such an event.
