Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that, early in the day, any ash clouds that rise above the crater rim could drift in any direction at low altitudes owing to light and variable winds. Any ash clouds that reach higher altitudes would drift southwestward. Later in the day any ash clouds would drift southward.

Recent observations: Seismic signals of rockfalls from the growing lava dome continue along with the typical background seismicity of one tiny earthquake every few minutes. The dome is largely obscured by clouds this morning, but clearing forecasts for the next few days should give us good views.
