    New snow is falling on either facets or old hard wind affected snow. It is likely that this new snow will not stick well to the old surface.

Confidence

Avalanche Summary

Observations are limited due to extreme cold. Given the cold temperatures, ongoing wind, and lack of recent observations, it is best to assume wind slabs may still be lingering in leeward terrain features in wind-affected terrain.

Snowpack Summary

Up to 30 cm of new snow is now sitting on a heavily wind affected and faceted upper snowpack.

Snowpack depths vary widely due to wind, but average around 130 cm across the region.
