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 eastward early in the day and east-southeastward later. Low-altitude winds are light and variable so any low-altitude ash clouds would drift slowly.

Recent observations: A weak vapor plume is rising from the actively growing western part of the new lava dome this morning. Seismic and ground-deformation data remain within well-established patterns.
