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 northward at low altitudes ranging to eastward at higher altitudes.

Recent observations: Intermittently clear views this morning from the VolcanoCam show a small vapor plume rising off the growing lava dome. There have been no significant changes in seismic and deformation data during the past day. Today is the last day that the Johnston Ridge Observatory will be open before it closes for the winter. Tomorrow Coldwater Ridge Visitors Center begins winter hours (10 a.m. to 4 p.m. Thursday through Monday).
