Regions

Little Yoho.

Small storms have slowly added up in Little Yoho and the ski conditions are excellent! Heads up if you are going to steeper or exposed terrain as small windslabs could surprise you!

Weather Forecast

The next few days look like an excellent time to get up high and enjoy some clear skies and light winds. A high pressure system is moving in and temperatures should be cool but not too cold with sunny skies and light north winds.

Snowpack Summary

A well settled snowpack with few weaknesses exists throughout the region. Small isolated wind slabs exist on leeward slopes in the high alpine. Below 1900m, the Dec 3 layer of surface hoar remains visible and produces hard, planar test results in some areas but has not been reactive to skier traffic. Thin snow pack areas are beginning to facet out.

Avalanche Summary

No new avalanche activity reported today. However, a skiier triggered size 1.5 windslab near Bow Summit yesterday indicates that windslabs are still a problem to watch for in isolated alpine terrain.

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.
