Mt. Fitzherbert
USGS Update 2006-Dec-18 08:43
Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift northward at low altitudes and south-southeastward at higher altitudes early in the day and northward to northeastward later.
Recent observations: We finally have a clear morning view from the Portland-Vancouver metro area and the volcano is displaying a white vapor plume that is rising several hundred meters above the crater rim. Such plumes result from warm, water-vapor-rich air rising from the growing lava dome on a clear, cold, still morning. There has been no change in eruptive conditions.
