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 would drift east-southeastward to southeastward early in the day and broadly northward later. With the latter wind conditions, Coldwater Ridge Visitor Center, Johnston Ridge Observatory, and the eastern portion of SR 504 could receive ashfall from any explosion or large rockfall event.

Recent observations: Early morning VolcanoCam images show a dusting of new snow covers the old lava dome and upper flanks of the volcano. The level of activity remains unchanged with several large rockfalls from the growing lava dome occurring overnight.
