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.

Recent observations: Field crews had a successful day in the crater yesterday, deploying three new instruments on the growing lava dome, one new instrument on the west arm of the crater glacier, repairing a field camera and doing maintenance work or field measurements at several other locations. Wispy vapor trails rose from the lava dome during the day but no significant plumes rose from the crater in the sunny but windy weather. Gas flights were postponed for a less windy day.
