Regions

Jasper.

As long as things stay frozen, and you avoid the isolated windslabs, conditions are pretty good.

Weather Forecast

Saturday: Cloudy with sunny periods and isolated flurries. Precipitation: Trace. Alpine temperature: High -5 C. Ridge wind west: 15-30 km/h. Freezing level: 1600 metres.

Sunday: Flurries. Accumulation: 6 cm. Alpine temperature: Low -10 C, High -5 C. Ridge wind southwest: 20 km/h gusting to 55 km/h. Freezing level: 1500 metres.

Snowpack Summary

Sun crust on solar slopes to Mountain top. Melt Freeze crust on polar slopes up to 2200m, settled snow on north aspects above. Moderate wind effect in the ALP.

Avalanche Summary

A few small wind slabs have been observed in higher elevation leeward features.

Confidence

Intensity of incoming weather systems is uncertain

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.
