Regions

Jasper.

Supportive skiing can still be found in well sheltered areas at TL and below.

Weather Forecast

Broken skies forecasted for Saturday. Progressive warming over the day and continuing thought the weekend. High's expected to be near -10 in the Icefields area.

Snowpack Summary

A layered, complex, shallow, faceted and weak snowpack. Multiple surface and buried wind slabs overlying a variety of faceted weaknesses to ground. Forecasters backed off a small alpine feature today due to a noticeable change in surface tension and hard hollow sounding wind slab. 

Avalanche Summary

A few loose slides observed from steep terrain today. Size 2 shallow wind-slab from the alpine (2600m, SW aspect) on a loaded rib feature on Boundary Peak

Confidence

Intensity of incoming weather systems is uncertain on Monday

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
