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 at high altitudes early in the day and to the north-northwest at high altitudes later in the day. At low altitudes, any ash clouds would drift to the northwest.

Recent observations: It is another quiet day here at Mount St. Helens, with good visibility into the crater of the volcano this morning. Seismicity and deformation remain at low levels, though lava continues to extrude onto the south crater floor. Several small earthquakes (M 2) have occurred in the past 24 hours, although these are not unusual
