New wind slabs are likely to form during the storm on Monday. These will be more reactive where they sit on a buried crust.

Confidence

Moderate -

Weather Forecast

Monday will be overcast with light flurries. Snow accumulations are expected to be between 10 and 15cm by end of day. Temperatures will remain steady near -5C with moderate to strong SW winds.

Avalanche Summary

No new avalanches observed today.

Snowpack Summary

A few flurries over the past 24 hours has done little to change the snowpack. Cooler temps and mainly cloudy skies kept the crusts frozen for the most part. On northern aspects, the snowpack is generally well settled with some isolated wind slabs in alpine terrain.

Monday could see 10 to 15cm of new snow with strong SW winds. This may lead to wind slab development at upper elevations.

Terrain and Travel

Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.

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.
