Snowpack Summary

Little Change. Surface hoar and melt freeze crusts are waiting for a load to bury them and then they will become a bigger concern. Thin shallow snowpack areas where is may be possible to trigger a collapse in the basal facets are still on our radar.

Problems

Deep Persistent Slabs

Basal facets and depth hoar still persist at the base of the snowpack. Skier triggering of this layer is still possible from thin or rocky snowpack areas. Choose routes that avoid these kinds of features especially in steeper terrain.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

2 - 6

Loose Wet

If the sun comes out on Monday, watch for decreases in stability related to daytime warming. Forecasts are calling for partly cloudy skies but, if the sun does come out, stability will decrease quikly.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.
