USGS Update 2008-Feb-09 08:27

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-southeast today, shifting to northeasterly by this evening.

Recent observations: Snowfall is tapering off at St. Helens this morning, but a resultant snowdrift has entirely blocked crater views via the USFS webcam at the Johnston Ridge Observatory. Up to a foot of additional snow is forecast to fall through tomorrow, and more snow is in the forecast for next week. Despite such accumulations, enough seismometer sites have their antennas poking above the snowpack for us to say with certainty that seismicity levels continue to be very low.
