USGS Update 2007-Jul-13 09:01

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 northerly.

Recent observations: Volcanic-related earthquakes remain sparse on a seismic record dominated by glaciogenic events and small rockfall. River turbidity following last week's stream-bank slips in the upper North Fork Toutle headwaters at Mount St. Helens has diminished to a static level only somewhat above pre-slip levels. The JRO volcanocam has been skulking in fog since dawn today.
