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 southeastward.

Recent observations: Extrusion of the new lava dome continues, despite relatively low seismicity levels. Mount St. Helens was visible intermittently this morning on the US Forest Service webcam. The volcano was showing off the season’s first snowfall and a gently rising steam plume could be seen. Since yesterday afternoon, 4 small earthquakes M1.4 to M 2.7 have occurred beneath the crater floor.
