More detailed information about the snowpack: 

Toured off the top of June mountain to Hemlock Ridge up standard route up and down, to 4 seasons trees to the rd.  

Very windy day at all elevations as a precursor to tomorrows storm.  122mph gusts ontop of June Mtn recorded in the morning.  Highway 395 closed in the afternoon.  See attached video near ridgeline ~9200'.  Windslabs building.  One natural release occured while we were there at low elevation, see seperate avalanche observation (D1 R2 - actively loading small steep slope).  Some isolated areas of shooting cracks up to a meter.  Storm snow has consolidated quite well (see attached profile), and the new concern being the actively building wind slabs.  Excellent skiing conditions in sheltered trees.  Later in day and tonight wind slabs will likely grow in depth and extent, with concern rising.  Mt. Wood had snow pluming down the east face all day non-stop.  Negatives had swirling winds, and looked like stripping and loading, and we stayed away from there.
