{"blocks":[{"key":"cbntg","text":"Several storm and wind slab avalanches of size small to large (size 1-2.5) were reported during and after the recent storm mid week breaking 20-40 cm deep. Observations have decreased since. Most avalanches released on the old snow surface which may consist of old wind slab, surface hoar or a sun crust on steep solar aspects. Triggered slabs have the potential to step down to the buried surface hoar layer from February 22, creating very large avalanches.

In many instances, slopes were ski cut with no results, only to have the third or fourth skier in the group trigger the slab. These avalanches have been remotely-triggered and have propagated widely across terrain features, warranting conservative terrain margins (see this MIN or this MIN for a helpful example). Observations extend to all aspects and elevations, but north to east aspects near treeline have been a hot-spot for reactivity.
