USGS Update 2007-Apr-21 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 to the east, northeast, and north.
Recent observations: Stormy weather has returned to the region and blanketed Mount St. Helens in clouds today, obscuring views from Johnston Ridge Observatory. Field crews took advantage of yesterday’s fine weather to perform aerial reconnaissance, service instruments, and install a new experimental camera system on the crater rim. Seismicity levels remain very low, and the character of the eruption remains unchanged from that of recent months.
