Regions

Jasper.

Extremely cold temperatures (-25, forecasted high for the Icefields) is the most significant hazard to the hardy back-country traveler today.

Weather Forecast

Cold air from the Yukon floods into our region as a arctic high pressure system builds. Cold easterly winds and 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, less in Maligne and around the three valley confluence. This layer is sitting on a variety of surfaces depending on elevation and aspect and seems to be bonding well. Surface hoar may be sporadically preserved in some sheltered locations.

Avalanche Summary

No new avalanches observed or reported

Problems

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.

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.
