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 northward to northeastward later. Under such wind conditions later in the day, Johnston Ridge Observatory and other areas near the east end of SR 504 could receive ash fall if there were an ash-producing event.

Recent observations: Another cloudy day obscures views of the volcano. The weather forecast for the next few days suggests that snow will be accumulating on the crater floor and upper flanks. Seismicity and ground deformation in the crater remain at relatively low rates, but lava extrusion probably continues to build the spine at the north end of the new lava dome.
