Mt. Fitzherbert

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

Potential ash hazards to aviation: Under current eruptive conditions, small, short-lived explosions may produce ash clouds that exceed 30,000 feet in altitude. Ash from such events can travel 100 miles or more downwind.

Recent observations: Stormy weather has obscured the volcano during the past 24 hours. A rain gage near the mouth of the crater measured about 2 inches of rain and acoustic-flow monitors (AFMs) showed increases in stream flow, but no evidence of debris flows. No changes were detected overnight in the ongoing patterns of earthquakes and ground deformation.
