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 today would drift northeastward.

Recent observations: The mountain is partly obscured by clouds this morning. When the clouds clear, ash from the explosions on Sunday, January 16, remains visible on the south and east crater walls. No field work is planned for today. Weather permitting, crews will be out next week measuring gas, temperatures on the lava dome, and obtaining new aerial photography. We have no immediate plans to replace the instrumentation damaged by last week's explosions.
