USGS Update 2007-Apr-23 08:30

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 at low altitudes and south-southeastward at higher altitudes early in the day. Later in the day any ash would drift northeastward at all altitudes.

Recent observations: Data from monitoring stations show no change in the character of seismicity or ground deformation as slow extrusion of the lava dome continues. We should have nice views of the volcano later today as low clouds disperse; possibly with a visible vapor plume rising above the crater rim.
