Regions

Kananaskis.

Well a return to winter with -20s even forecast this upcoming week! Recent snow from the past few days is creating windslabs in alpine terrain along ridgelines. Pay attention as you move into wind affected terrain. 

Confidence

Moderate -

Weather Forecast

10-15cm of snow is forecast with day time highs are -8C and generally light winds. We were headed to spring, but are returning to winter here this next week!

Avalanche Summary

No new avalanches observed or reported

Snowpack Summary

On average 7cm of snow fell at treeline over the past 24hrs with a moderate NW flow at upper elevations. This snow is overlying a well settled snowpack on northern aspects and more of a spring crusty snowpack on the solar aspects. With the more northern flow, we may see isolated windslabs on all aspects in the alpine.  

Terrain and Travel

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

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.
