Regions

Jasper, Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Maligne, Marmot, Miette Lake, Pyramid.

Watch for isolated pockets of wind slab in leeward alpine features.

New snow will improve ski quality but forecasted amounts are variable; if more snow falls than is expected, evaluate the changing conditions accordingly.

Confidence

Moderate

Avalanche Summary

No new avalanches observed or reported.

If you have any recent observations, please submit them to the Mountain Information Network.

Snowpack Summary

2-10cm of new snow has fallen on a surface crust that exists up to 2200m all aspects. Above 2200m 5-10cm dry snow sits on a supportive crust that exist up to 2600m on all aspects, and to mountain top on solar slopes. Strong upper and mid-pack, supportive to skis and boots. Lower snowpack consists of basal depth hoar.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.

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.
