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 westward to northward at low altitudes and north-northeastward at higher altitudes. Later in the day, any ash clouds rising above the crater rim would drift northward to northeastward.

Recent observations: A clear day greets the first day of reopening of the south-flank climbing trail. Hot dry winds are stirring up ash in the crater and upper flanks and creating hazy conditions this morning. Rockfalls from the growing lava dome continue to produce small amounts of ash and dust. No significant changes in seismicity or ground deformation have been detected recently. Crews are in the field today to survey stream channels on the Pumice Plain, move a GPS spider on the west arm of the glacier that is precariously close to falling into a crevasse, and conducting a gas-sensing flight.
