Mt. Fitzherbert

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 northeastward.

Recent observations: Clouds are obscuring the view into the crater from Johnston Ridge Observatory this morning, and the weather will preclude any field work until next week at the earliest. Seismicity remains at a level typical of recent days and weeks, indicating that lava extrusion is continuing. As soon as weather allows, priority for field operations will be given to replacing or repairing the monitoring instruments on the 1980-1986 dome that were damaged by the rockfall and avalanche of May 29.
