Regions

Brandywine, Garibaldi, Spearhead, Tantalus.

Continued reverse loading is building wind slabs in lee terrain. Take extra caution when transitioning into wind affected slopes.

Confidence

Moderate

Avalanche Summary

On Sunday there were small dry loose avalanches reported from steep terrain.

No new slab avalanches have been reported since Friday when two separate parties accidentally triggered wind slabs near Whistler, and whumpfing was described in this MIN report.

Snowpack Summary

Due to shifting wind at upper elevations, the surface snow has likely been changed by the wind. However, cold temperatures are helping to facet or soften slabs that were formed. Riding quality is generally good in sheltered areas as the cold has kept the surface soft. There may be a thin melt freeze sun crust on steep solar aspects.

A weak layer that was buried at the end of January is down 30 to 80 cm in the snowpack. Depending on where you are, it'll be a combo of different crystals. With crusts on sunny slopes, sugary facets in most places, and surface hoar in sheltered spots.

The mid and lower snowpack is well-settled with no layers of concern.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Make observations and continually assess conditions as you travel.

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.
