USGS Update 2007-Nov-21 09:17

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 south at low altitudes and southeast at high altitudes. Late in the day, winds would carry clouds to the west at low altitudes and to the south-southeast at high altitudes.

Recent observations: Monitoring data show no change in eruptive conditions. Another beautiful day in the Pacific Northwest brings clear skys to Mount St. Helens today. A field crew is at the volcano, working to install a new tiltmeter in the crater and making observations.
