@ai6yr Ash resuspension happens all the time with the deposit of the Novarupta 1912 eruption. First time I hear about it at Mount St Helens, though, pretty cool!

@ai6yr Probably concern over wind-blown ash. It happens sometimes. https://katu.com/news/local/wind-to-blow-ash-off-mount-st-helens-into-washington-communities
Strong winds blow ash off Mt. St. Helens

SKAMANIA COUNTY, Wash. -- That was no volcanic eruption Sunday, but some areas to the west of Mt. St. Helens must have wondered after some ash was spotted blowing in the area. Instead, it was strong east winds carrying ash from past eruptions off the mountain and carrying it west, according to forecasters with the National Weather Service in Portland.
