Be on the lookout for lingering wind slabs in the alpine. Avoid likely trigger spots such as shallow, rocky, wind affected areas.

Summary

Confidence

Weather Forecast

Wednesday: Cloudy with flurries / Light to moderate southwesterly winds / Freezing level around 1100 m. Thursday: Mix of sun and cloud / Light westerly winds / Freezing level at valley bottom. Friday: Stormy with 5-10 cm snow / Strong westerly winds / Freezing level around 1000 m.

Avalanche Summary

No new avalanches were reported on Monday, however, there is currently very limited data for this region. Please report your observations to the Mountain Information Network(MIN).

Snowpack Summary

Observations are very limited in this region. Last weekend's storm delivered up to 30 cm of snow and as much as 100 cm over the past week. The new snow has created storm slabs in alpine and treeline elevations. Expect to find wind slabs in wind affected alpine terrain. The mid-November crust is down around 100 cm. Average snowpack depths at treeline are 140-170 cm with generally less snow in the northern parts of the region. Below treeline rocks, stumps, and open creeks remain the primary hazards.

Problems

Wind Slabs

Recently formed wind slabs may remain reactive to human triggers for several days.

Avoid slopes that sound hollow or drum-like.Travel on ridgetops to avoid wind slabs on slopes below.Be cautious as you transition into wind affected terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Expected Size

1 - 2

Storm Slabs

Storm slabs may remain touchy even though the storms have passed, especially at higher elevations and on wind-loaded features.

Avoid regrouping in runout zones.If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.

Aspects: All aspects.

Elevations: Alpine, Treeline.
