Snowpack Summary

Up to 100cm new snow in the last 48 hours with very little wind effect. This overlies wind slab and a variety of weak layers near the ground.

Avalanche Summary

Widespread avalanche activity on all aspects and elevations up to size 3.0. Many dry loose avalanches below treeline and above, numerous storm slab avalanches below treeline and above. Several avalanches stepped down to weaknesses near the ground. Much of the alpine was obscured today but it is expected that many avalanches occurred on all aspects

Confidence

Due to the number of field observations on Sunday
