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 predominantly east.

Recent observations: The crater is not visible from Johnston Ridge early this morning, though the weather may improve later in the day. Monitoring instruments continue to record small earthquakes, rock falls and steady ground deformation consistent with on-going extrusion of the lava dome. There have been no significant changes in conditions over the last 24 hours.
