Regions: Kananaskis.

It is important to be disciplined with terrain choices. Many slopes look quite attractive with the recent snow, but the Feb 10th layer still needs time to heal. Human-triggering remains likely.

Confidence

Good

Weather Forecast

Thursday will bring cloudy conditions with a trace amount of snow possible. Winds will be moderate from the NW and temperatures should reach -8 in the alpine. Beginning Friday temperatures will cool significantly with the thermomotor dipping to -38 on Saturday night! Cloudy conditions should prevail through the weekend with a chance of very light flurries.

Avalanche Summary

Nothing new observed or reported but observations were very limited today.

Snowpack Summary

Moist snow on steep solar aspects. Surface facetting in protected areas. Snowpack settling. Wind effect Alpine and Treeline areas. Between 40 and 70cm overlies the Feb 10th layer. Moderate shears are found at this interface.

Avalanche Problems

Persistent Slabs

Naturally triggered avalanche activity has subsided, but human triggering remains touchy. The Feb 10 persistent weak layer will be a problem for some time and is now buried 35 and 70cm. Whumpfing and cracking have been observed in recent days.
Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.>Be cautious as you transition into wind affected terrain.>Avoid steep, open slopes.>

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 4
