USGS Update 2007-May-19 10:53

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 northeastward.

Recent observations: Views of Mount St. Helens from Johnston Ridge Observatory are partly obscured by clouds this morning. There have been no detectable changes in seismicity or deformation. A seismic station placed on the growing dome survived nearly an hour of shaking this morning, possibly from a series of nearby rockfalls.
