On Monday, a skier triggered a size 2 wind slab on a NE aspect at 1300 m. Several loose avalanches also failed on steep sunny slopes. Click on the blue dot on the map to see a recent wind slab that may have failed naturally or remotely in Sinclair. It was a thick, hard wind slab on a north aspect. There are likely to more like this lurking. New snow and wind on Thursday will likely promote further wind slab activity.

Anywhere from 20 to 120 cm recent storm snow has been redistributed by winds into soft and hard wind slabs at alpine and treeline elevations (highest storm snow amounts were in the north and west). This overlies various surfaces including old wind slabs, hard crusts, surface hoar, and/or surface facets. New snow and wind on Thursday is forecast to form new wind slabs in exposed lee terrain.At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile. Below treeline, the snow appears to be in a spring melt-freeze cycle.
