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 southeastward.

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: The volcano is shrouded in clouds this morning, and inclement weather is forecast for the next several days. A new seismometer slung by helicopter to the old lava dome Tuesday is functioning well. We have now replaced a few stations within the crater lost in last week's explosive event. As time and weather allow, we will gradually replace more of the lost equipment.
