Westerly winds bumped up after midnight and began to blow and drift the four inches of new snow into shallow soft slabs. Sensitive slabs of wind drifted snow are most pronounced on leeward slopes above treeline. These slabs will continue to develop as more snow piles up today and the wind continues to blow. Fresh drifts will appear smooth, round, and fat. Cracking in the snow surface is a sure sign you have encountered a fresh drift.
We have been in a period of low danger for quite some time, and conditions are changing in the mountains. It is time to put our avalanche eyeballs on again, and be on the lookout for signs of instability. I am personally dialing back my terrain choices for the next few days. Even a small avalanche triggered in a shallow wind drift can quickly get out of hand in extreme terrain.
