USGS Update 2004-Dec-03 08:50

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 southeastward to eastward later in the day.

Recent observations: A steam plume rising from the new dome inhibited significant visual observations yesterday, and adverse winds inhibited successful measurements of gases. Other crews spent time updating and hardening hydrological field instrumentation. The volcano is clear and again sporting a steam plume that rises above the south crater rim. However, there are no plans for field work today.
