Mt. Fitzherbert

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 northeastward in the morning and eastward in the afternoon.

Recent observations: Gusting winds from a strong winter storm has increased the background noise recorded by seismic and tiltmeter monitoring instruments on Mount St. Helens. We note no change in the number or size of earthquakes, rockfalls, or slow ground deformation events. This sporadic activity is consistent with continued slow growth of the lava dome.
