Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim would drift to the east-northeast.

Recent observations: No significant changes in the level or type of activity at the mountain have been noted since yesterday’s update. The series of winter storms sweeping through the area over the last several days have dumped several feet of snow onto instruments located on the flanks and crater floor of Mount St. Helens. Most continue to function admirably, although occasional radio signal dropouts from several instruments occurred overnight. Given the dense network of stations on the volcano, the dropouts are not having an appreciable affect on our monitoring capabilities. With the forecast calling for several more feet’s-worth of snow through the end of the week, it is likely that occasional dropouts will continue to occur.
