Red Flags Comment
<p>We intentionally triggered on small wind slab (2-8 inches deep and 15 feet wide). Other wind slabs and drifts would crack (one collapsed) but they would not move.</p>

For the next several days until we get more snow, I think the snowpack should get weaker mainly on northerly aspects. It may get warm enough on southerly aspects. Time will tell.

Instability Comment
<p>If there was no wind slab or wind loading, there was no avalanche concern. There were two weak layers on which the wind slabs would fracture. One was facets almost at the ground in the old snow. In some cases these facets were beneath a harder layer of old snow. The other weak layer was new snow particles about 4-6 inches down from the surface. These stellars and other precip particles seemed to have faceted slightly since yesterday and were very loose and cohesionless.</p>

I was surprised at the minimal wind effect. In most places the trees were still covered in snow, even at the top of Catherine's Pass. We did see some plumes of snow from NW winds off Baldy in the morning.
