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 southeastward.

Recent observations: Clouds obscure views of the crater today, but small earthquakes and slow ground deformation indicate ongoing extrusion of the lava dome. There have been no significant changes in conditions over the last 24 hours.
