Regions: South Coast.

Unusually warm alpine temperatures may drive danger up.Thanks to everyone who has been submitting to the Mountain Information Network. Join the movement!

Weather Forecast

Cold in the valley, but above zero at treeline/alpine elevations. The freezing level is expected to rise up to around 2700 m this weekend. No precipitation is forecast. Valley cloud is possible on Friday.For more details check out avalanche.ca/weather

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

There is anywhere from 30-150 cm on the ground. Recent northerly outflow winds have scoured upwind slopes back to a firm crust, and created wind slabs on lee aspects. The snowpack is highly variable across different aspects and elevations.Wind slabs could be triggered by the weight of a person, especially where they overlie surface hoar, crusts or facets. The other big story is unusual warming at alpine elevations, which may weaken surface layers, or even wake up deeper snowpack weaknesses. Id take a cautious approach to big/ exposed terrain until winter temperatures return to normal.

Avalanche Problems

Wind Slabs

Wind slabs may be lurking near, or well below, ridge crests. Conditions are highly variable, so be alert 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: Possible - Likely

Expected Size: 1 - 3

Loose Wet

Unusually warm alpine temperatures may weaken surface snow and lead to loose wet avalanches.
Watch for clues that indicate that the snowpack is warming up, like sluffing off of cliffs, snow balling and natural avalanche activity.>

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3
