Regions

Waterton Lakes, Waterton.

Skiing is poor in many areas due to series of wind events and minimal snow in the past week, but decent skiing may exist on very sheltered slopes below treeline.

Confidence

Moderate

Avalanche Summary

A few windslab avalanches to size 1.5 have been observed in the park in the past week.

Snowpack Summary

5-10 cm of snow fell over last weekend and is now very wind affected. The windslab overlies stiff old windslabs, a layer of facets, or a melt freeze crust below treeline and in steep solar locations at higher elevations. Ski quality is generally poor as the surface snow is hard or is unsupportive and breakable. The lower snowpack is well settled with no significant weak layers.

Snowpack depths at treeline range from 80 - 120 cm.

Weather Summary

Thurs

Mainly cloudy with isolated flurries. Alpine high of -9°C with wind southwest 40 km/hr gusting to 70

Fri

Cloudy with sunny periods and isolated flurries. Wind north 50 km/hr becoming 20 and a high of -9°C in the alpine.

Sat

A mix of sun and cloud. Wind west 15-30 km/hr. Alpine high of -11°C.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.

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.
