USGS Update 2007-May-16 10:01

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 northeastward.

Recent observations: Low clouds partly obscure views of the crater from Johnston Ridge Observatory this morning. A shallow magnitude 2.7 earthquake occurred yesterday at 4:14 PM PDT. Sporadic micro earthquakes, frequent rockfalls, and slow, steady growth of the lava dome continue.
