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 north-northeastward early and northeastward later.

Recent observations: Following a brief respite, storms have moved back into the region and several inches of new snow are expected to accumulate at the mountain. Ash deposits from dust clouds associated with continued rockfalls from the new dome will probably intermingle with and discolor new snow within the crater. If ash clouds rise above the rim, discolored snow may also be visible on the flanks when the weather clears again. Seismicity remains unchanged over the past few days, and is characterized by ongoing small quakes occurring once or twice per minute punctuated a few times per day by larger quakes. When conditions permit, crews will replace equipment pulled from the crater on Sunday, and make gas measurements and further observations.
