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 southeastward.

Recent observations Clouds obscure the crater today, but favorable forecasts suggest that by tomorrow afternoon the weather should be clear. There have been no changes in eruptive activity in the past 24 hours, and seismicity remains relatively low. A M2.9 earthquake at 12:52pm local time yesterday may have been accompanied by a rockfall. Events of this type are common under the current style of eruptive activity, and similar events are likely to occur again. Field crews hope to exploit the improving weather in the next few days.
