Regions

Waterton Lakes, Waterton.

Ski quality is improving but watch for buried hazards as you get down into lower elevations.

Confidence

Low

Avalanche Summary

One Na size 1.5 avalanche was observed in steep unsupported terrain at treeline.

Snowpack Summary

Strong to Extreme SW winds have redistributed 50cm of storm snow into windslabs at all elevations. This overlies wind-affected old surfaces and pockets of windslab in the alpine and at treeline. The lower snowpack is a variety of old surfaces including facets, crusts, and windslab. A spotty crust exists at the very bottom of the snowpack in deeper locations.

Below treeline windslab overlies settling storm snow and early-season snow in the form of facets and crusts.

Weather Summary

Friday

Overcast with light flurries. Total accumulations less than 5cm. Temps in the alpine will be around -8 with moderate west winds.

Saturday

Cloudy with PM flurries. Alpine temps -3. Winds moderate SW.

Sunday

Cloudy with flurries. Alpine temps -5. Winds light out of the south.

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.
