Regions

Jasper.

Convective flurries have brought some good skiing to the region. Snowfall amounts vary depending on geographic location.

Weather Forecast

The next few days will see varied conditions though the region. Winds will be calm to light from the south. Light precip can be expected of the next couple days until Saturday evening where up to 15cm is forecasted. 

Snowpack Summary

Up to 30cm of new snow with convective flurries and favorable SW winds have redistributed the low density, new snow over previous surfaces such as hard windslab and varied crusts at TL/ALP elevations. The snow pack varies throughout the region from strong supportive snow in deeper areas to weak facetted snow in the shallow areas.

Avalanche Summary

No new avalanche activity observed or reported today. A small few loose dry avalanches were triggered by skiers in steep alpine terrain

Confidence

Timing, track, or intensity of incoming weather system 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.

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.
