USGS Update 2006-Aug-19 09:20

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 would have a northwesterly drift.

Recent observations: Skies are clear at Mount St. Helens this morning. Continued slow-but-steady growth of the latest lava spine is apparent from the faint murmur relayed from seismic instruments in the crater. Field crews deployed in the crater and around the rim yesterday completed repairs on several seismic stations and repaired or installed remote cameras used to monitor eruptive activity.
