Issued: Nov 28th, 2018 3:00PM

The alpine rating is low, the treeline rating is low, and the below treeline rating is below threshold. Known problems include Wind Slabs and Deep Persistent Slabs.

Skiing is pretty rugged right now.  Ice climbers watch for pockets of hard wind slabs above and along routes.

Weather Forecast

Avalanche Summary

No new avalanche activity seen or observed.

Snowpack Summary

40-50cm of snow is overlying the October crust at TL elevations. No significant sheers were noted within the snowpack. Lens of hard slabs in alpine areas that are overlying the weak facetted base are the main concern at this time. Thin weak spots are good triggers for these hard slabs so be mindful of that. Ice climbing conditions are great while skiing.... no so great.

Problems

Wind Slabs

An icon showing Wind Slabs
Lens of hard slabs should be expected in alpine areas. Thin weak spots at the edges of these lens should be treated with caution.
Be careful with wind loaded pockets while approaching and climbing ice routes.Use caution in lee areas. Recent wind loading have created wind slabs.

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

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 2

Deep Persistent Slabs

An icon showing Deep Persistent Slabs
This crust is mostly found on or near the ground. This layer has not been active lately, but there is potential for slab avalanches on this layer given the current snowpack structure.
Carefully evaluate terrain features by digging and testing on adjacent, safe slopes.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely

Expected Size

1 - 2.5
