Snowpack Summary

Variable hard surfaces that developed during the recent dry spell have been buried by 10-15 cms of new snow. A weak layer of surface hoar or near surface facets was reported on the surface before being buried. Incremental snow falls are expected to continue to build a new storm slab above these weak layers and sliding surfaces.

Avalanche Problems

Storm Slabs

The new snow may be sitting on a hard layer like an old wind slab or a sun-crust. There may also be a weak layer of surface hoar or facets sandwiched between the new snow and the old surface. Pockets of deep soft new wind slab may also be found.
Avoid freshly wind loaded features.>Be cautious as you transition into wind affected terrain.>
