Regions

Jasper.

Be prepared for the weather as one would say. Northerly winds and cold temperatures are forecast for the next while.

Weather Forecast

Arctic high pressure system. Cold north and easterly winds with clear skies will remain in place most of the week. For more details: Avalanche Canada's, Mountain Weather Forecast.

Snowpack Summary

30cm of low density snow fell since Saturday in the ice fields area, with less in the Jasper town area. Recent reverse loading may have created wind slabs in the immediate lee in the alpine. This new snow is sitting on a variety of surfaces from wind scoured in the alpine to preserved surface hoar in the protected treeline features. 

Avalanche Summary

No new avalanches observed or reported. No field observations for several days. 

Confidence

Due to the number of field observations

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.
