Regions

Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

Recent snow has refreshed the skiing once again but the sun gets to it quickly on solar aspects. Shady aspects are still dry and skiing well.

Confidence

Avalanche Summary

No new avalanches were observed. Some very small loose dry sluffs were observed in steep cliffy terrain.

Snowpack Summary

The forecasters went up to Sarrail ridge today up to 2400m. They found up to 10-15cm sitting on a recent suncrst that was 1 cm thick. The polar aspects were still dry and no wind effect or wind slabs were noted. Valley floor temperatures reached +1c and had moist snow.

Weather Summary

Snow ending Thursday evening for a total of 10cm valley dependant. Friday will bring mostly cloudy skies with sunny breaks and possibly a flurry. Temperatures on Friday will be between -6c and -1c in the Alpine, warmer at valley bottom. Winds are forecast to blow from the NW up to 40km/h.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

Carefully evaluate steep lines for wind slabs.
Be careful as you transition into wind-affected terrain.
Be alert to conditions that change with elevation and sun exposure.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
