USGS Update 2007-Jun-16 10:20

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 today would drift east-northeast shifting to east-southeast by this evening.

Recent observations: Grey or gray; no matter the spelling, that's the color of the view at Mount St. Helens this morning. What lies behind the grey/gray curtain? Nothing unusual, if unusual includes the continued slow but steady eruption of a dacitic lava dome accompanied by rockfalls off the dome's steep-sided edges, occasional earthquakes, and glacier quakes from the rapidly-moving Crater Glacier. The weekend's forecast calls for continued cloudy and occasionally wet weather, but good viewing conditions should return by early next week.
