Avalanche Summary
No notable avalanches were reported on Friday.
We expect that a natural storm slab cycle will take place starting early Sunday morning.
Snowpack Summary
New storm and wind slabs will form throughout Saturday night and Sunday. This will also add to the already large cornices.
Up to 30cm of previous storm snow sits over a layer of small surface hoar, facets and wind effected surfaces. Below treeline a new crust could exist up to 1000m.
A layer of facets and a crust from late January can be found down 100 to 200cm. Below this layer the snowpack is generally well settled and right side up.
