USGS Update 2007-Aug-09 11:30

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 eastward to northeastward.

Recent observations: Some clouds still obscure the crater from the north, but weather is improving. Seismicity at Mount St. Helens have not changed significantly in the past few days, although a magnitude 7.5 earthquake, which originated near Jakarta Indonsia at 10:04 AM PDT yesterday, showed up nicely on some of the stations around the mountain.
