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 northeast in the morning but east by afternoon.

Recent observations: The volcano extrudes a lava spine placidly this morning, judging from the background seismicity and sparse GPS data. A few earthquakes reach into the M2 to M3 range each day, and all earthquakes are within 1.5 km of the vent. Small inconsequential rockfalls may be associated with some of the earthquakes. State Route 504 to Coldwater Ridge visitor center reopened earlier this week following a landslide closure.
