New snow has been transported by variable winds and formed reactive slabs on all aspects.
Gather info in simple terrain, free from overhead hazard, before increasing your exposure.
On going snowfall has formed at storm slab at all elevations. Expect to find deeper deposits and windslab in areas lee to the prevailing wind.
On Friday, a large avalanche was reported that was likely to have occurred in the storm during the middle of last week.
Natural avalanche activity has slowed after the storm with the temperature dropping.
It remains possible for riders to trigger avalanches.
Up to 80 cm of light, dry snow has fallen over the past week. In the middle of the snowpack is a layer of surface hoar and/or faceted grains. The layer of facets may have a hard melt-freeze crust underneath.
In thin snowpack areas, faceted grains or depth hoar may extend to the ground. Recent variable moderate winds has redistributed this new snow, forming wind slabs on all aspects.
Average snow depths at treeline range from 100 to 170 cm and decrease rapidly at lower elevations.
