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 southward to southeastward early in the day and eastward later.

Recent observations: The VolcanoCam at Johnston Ridge Observatory is in the clouds this morning, but the DomeCam, which is located near the crater mouth, shows a moderate vapor plume rising from the growing lava dome and drifting over the south crater rim. This is yet another example of meteorological conditions that favor condensation of the warm, moist air in the crater as it rises and cools. If the low clouds in the valleys clear, tourists at JRO and those of us in the metropolitan area may see the vapor plume.
