Regions

Glacier.

Use caution entering wind affected terrain as wind slabs may be reactive to your presence.

Excellent snow quality found throughout the Park.

Weather Forecast

Get your Vitamin D fix on Monday, after that we're back into another storm cycle and won't see the sun for a few days :)

Monday will see a mix of sun and cloud with isolated flurries, an Alpine high of -4, freezing level to 1200m and 30-50km/hr SW winds. The next storm arrives on Monday evening and is forecasted to bring another 50+cm by Thursday.

Snowpack Summary

60cm of recent low density snow with 25-50km/hr SW winds is forming new wind slabs. The warming temps will promote settlement of the low density snow. The Dec 1 crust (now buried up to 2m deep) remains dormant, despite having faceted snow above and below it. The mid-lower snowpack is settled and strong.

Avalanche Summary

Several Sz 2.0 wind slabs observed from steep, wind loaded start zones from Mt. MacDoanld and Mt. Tupper.

A natural cycle up to sz 2.5 occurred on Saturday from all aspects, originating in steep terrain and likely being triggered by increasing winds.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Tuesday

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.
