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 westward, but with enough variation that Johnston Ridge and parts of Highway 504 could receive ash fall.

Recent observations: The nice vapor plume that was visible earlier this morning has now dissipated and the new lava dome and crater are clear. There has been no change in the level of activity from that of the past few weeks. Early morning and evening atmospheric conditions have been favorable for production of visible vapor plumes, so we may see one later this afternoon and evening.
