Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim would drift southeast in the morning, changing to northeast by afternoon.

Recent observations: The mountain is within a major winter storm cell and is expected to receive between 1 and 2 feet of snow today. Our instrumental signals indicate no significant change in patterns of seismicity. The GPS receiver on the new dome continues to plow westward at about a meter per day, with little change in vent conditions as indicated by tilt stations on the old dome both northeast and northwest of the vent area.
