Regions

Jasper.

Steep sun exposed slopes may become unstable by mid-day.  Ice climbers should pay attention to this condition.

Weather Forecast

A few flurries are possible into the weekend, however they will only provide a trace of accumulation.  Temperatures will remain mild for this time of year with increasing influence from solar radiation in the afternoon.  Winds will be light from the SW.

Snowpack Summary

Hard windslab is bridging the weak basal facets on most lee aspects above treeline.  The treeline mid-pack continues to weaken as the faceting process continues and below treeline the snowpack is thin and weak.

Avalanche Summary

No avalanche patrols were conducted today.

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.
