Regions

Jasper.

Cold and clear, enjoy the blue skies.

Weather Forecast

Cool temps expected throughout the week, with clear skies and no new precipitation. Winds chilly and light from the North. Slightly warmer temperatures expected for the weekend.

Snowpack Summary

Recent cold temperatures are weakening the snowpack. Isolated pockets of windslab in exposed areas above treeline. Alpine is scoured in many places, leaving dirt, rock or shallow snow cover. Surface hoar formation and faceting is expected to be widespread.

Avalanche Summary

No avalanches observed or reported.

Confidence

The weather pattern is stable

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.
