Recently formed storm slabs may still be reactive to human triggers. Use additional caution in shallow, rocky, or wind affected alpine terrain. Please post your observations to the Mountain Information Network.

Weather Forecast

Tuesday: Mix of sun and cloud / light southwesterly winds / Freezing level around 700m. Wednesday: Cloudy with possible flurries / Light westerly winds / Freezing level around 1000m. Thursday: Mix of sun and cloud / Light northwesterly winds / Freezing level around 900m.

Avalanche Summary

No new avalanches were reported on Sunday, 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. Up to 40 cm of recent snow has created storm slabs at alpine and treeline elevations. Expect to find the mid-November crust down 60-80 cm. Average snowpack depths in the alpine are 110-150 cm with generally less snow in the southern parts of the region. Early season hazards such as stumps, rocks, and open creeks remain the primary concern below treeline.

Problems

Wind Slabs

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

Be cautious as you transition into wind affected terrain.Avoid areas where the snow feels stiff or 'slabby'.Travel on ridgetops to avoid wind slabs on slopes below.

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

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3

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

Aspects: All aspects.

Elevations: Alpine, Treeline.
