USGS Update 2004-Dec-23 09:00

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim today would drift southward.

Recent observations: The VolcanoCam is providing clear views of the volcano this morning and there should be good views from the lowlands once the fog lifts. A moderate steam plume is rising from the new lava dome and drifting over the south rim of the crater. Field crews are on their way to service seismic stations and to complete repairs to a key radio transmitter. They will also attempt to retrieve one of the Spiders (a portable seismic and GPS station that was slung into place by helicopter) from the old lava dome and replace it with a newer version.
