USGS Update 2006-Aug-09 08:00

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 mostly north-northeastward.

Recent observations: At this hour the mountain is still shrouded in fog. A magnitude 3.3 earthquake rattled the mountain last night at 8:02 PM, and a magnitude 2.4 aftershock of the M 3.8 earthquake of August 3 near Battle Ground was recorded on stations at Mount St. Helens at 7:32 this morning. No significant rockfalls were noted during either of these events.
