Snow Characteristics Comments

Saw a little of everything out there today.  A few inches of snow from yesterday was all blown around and lying in a select few places.  Elsewhere had everything from supportable windslab to wind crust, to MF crust.  Snow down low at ~7,500' was pretty warm and damp.

Red Flags Comments
Saw one natural windslab that had gone this morning on a NNE aspect around 10,300'. We were able to ski cut out one wind slab that was about 100' with a depth of 6"~16". Lots of snow being transported along the ridgelines.

Problem #1 Comments

Observed two windslab avalanches today, one natural and one skier triggered.  Got a report of one other windslab releasing skier triggered.  Not widespread, but I would expect these to become deeper and stiffer with continued winds and the forecasted new snow tonight and saturday.
