Regions

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

The Alpine is the main area where there is a snowpack to discuss. Watch for windslabs along ridgelines and in gullied terrain if you do head out. With the cooler temperatures we may start to see some more ice beginning to form.

Confidence

Moderate

Avalanche Summary

No new avalanches

Snowpack Summary

Unfortunately there has been little change of late and the warm temps have developed widespread surface crusts across the region.

Wind slabs are still the dominant problem in alpine areas. Ridgelines, gullies and cross-loaded features are areas to pay close attention to as you move higher in the terrain.

Treeline and below is still pretty shallow for snow. Its a long season here so think about your knees!

Weather Summary

A mix of sun and cloud with strong SW flow. No new precip is forecast. Temps around -4C. See tables below.

Terrain and Travel Advice

  • Ice climbers should be equipped with avalanche safety gear.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.

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.
