New snow continues to accumulate and may require additional time to properly bond to the underlying surfaces.




Avalanche Summary

Numerous skier-triggered, explosive-triggered, and natural storm slab avalanches were reported on Wednesday. In general, reported avalanches occurred at alpine elevations and on a variety of aspects, up to size 2.

Widespread avalanche activity would lead us to believe that the new snow is poorly bonded to underlying surfaces.

If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Variable alpine winds have redistributed surface snow at higher elevations. New snow has buried a variety of old wind-affected surfaces, along with widespread faceted crystals, which will likely prolong the bonding time between new snow and the surfaces below.

The mid and lower snowpack consists of various old crusts and is generally well-settled and well-bonded.
