Sherwins - heads up conditions - whoomphing, remote triggering

Heads up snowpack in the Sherwins right now.  Dug one pit (attached) in opening in the trees around 9600', which showed a deep layer of facets in part of the pit, but not in another part of the pit (30cm above ground), test results were not too concerning.  But at similar elevation across the slope heard/felt a couple heafty whoomphs, one of which shook snow from the branches of small trees 100ft across the slope, and triggered a 3+ foot crown mid-slope in the middle of a steep rocky outcrop (see attached photo).  This crown was a small pocket only about 25ft across, but it was triggered from about 100ft away, and it was a solid 3ft in height, and appears to have released in some above ground facets.  A couple more small wind slabs were triggered in much more expectedlocations just below the ridgeline and about 400' down slope from the ridgeline along a rocky rib (see attached photo - both about 10" crowns).

Northerly winds over ridgetops were much higher than expected, blowing at moderate level, with banners seen across the mammoth crest in the late afternoon.
