Issued: Nov 29th, 2015 7:57AM

The alpine rating is below threshold, the treeline rating is below threshold, and the below treeline rating is below threshold. Known problems include Wind Slabs and Loose Wet.

pgoddard, Avalanche Canada

South Coast.

Incoming snow and winds may drive avalanche danger up early in the week.

Summary

Confidence

Poor - Due to the number of field observations

Weather Forecast

Light snow is expected to begin late Monday and continue on Tuesday. Â Around 10 cm snow is expected on Wednesday. Ridgetop winds are moderate to strong southerly. The freezing level is expected to hover around 1200 m, rising towards 1600 m on Wednesday.For more details check out avalanche.ca/weather

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

The snowpack is highly variable across different aspects and elevations. There is anywhere from 30-150 cm on the ground. Previous northerly outflow winds scoured upwind slopes back to a firm crust, and created wind slabs on lee aspects, which are gradually gaining strength. Shallow snowpack areas may be rotten (facetted). Recent warm and sunny conditions in the alpine are likely to leave behind sun/temperature crusts. Forecast incoming storm snow may bond poorly to this cornucopia of surfaces.

Problems

Wind Slabs

Hard wind slabs may be found on a variety of slopes. Pay attention to hollow, drummy sounds and changes in the feel of the snow as you travel.

Be cautious as you transition into wind affected terrain.>Watch for whumpfing, hollow sounds, shooting cracks or recent avalanches.>

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

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 3

Loose Wet

Unusually warm alpine temperatures may weaken surface snow and lead to loose wet avalanches.

Watch for clues that of snowpack warming, like sluffing off cliffs, snow balling and natural avalanche activity.>

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 3
