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 westward early in the day. Later in the day, lower altitude clouds would drift east-southeastward and higher altitude clouds would drift southward.

Recent observations: The volcano is once again obscured by clouds. Seismic and deformation data continue trends of the past few weeks, from which we infer continued lava-dome growth. We're hoping that conditions will improve on Thursday and permit field observations and a gas-sensing experiment.
