Kernpunkte

Slow warming expected through the week. Plan your weekend objectives with this in mind: start early, end early!

We are cautiously gaining confidence in the snowpack; dig and investigate persistent weak layers before committing to slopes. Reactive wind slabs are building in the alpine.

Great skiing can be found at all elevations.

    Continued new snow and wind will produce wind slabs on leeward features.

    The March 20 crust is buried 20-60cm and producing sudden planar results in tests. The Jan 24 facets are 80 to 120cm deep and were active in the recent cycle. Dig down to investigate how these layers are adjusting to the new load. Slopes that have not released naturally should be treated with caution.

    Progressive warmup leading into the weekend. Solar aspects will be getting cooked late into the afternoon.

Confidence

High

  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

The field team noted a previous natural cycle, with new wind slabs noted in alpine features.

Snowpack Summary

Around 15 cm of new snow has fallen this week, redistributed by W winds. Below, a firm crust is supportive at low elevations but gradually disappears above treeline, around 2300 m. A deeper PWL from late January persists, down 80–120 cm. The lower snowpack is generally strong, though a weak, faceted base exists near the ground. Total snow depths vary across the region, with deeper coverage along the Icefields Parkway (150–220 cm) and less in the Maligne area (60–140 cm).

Thursday: A mix of sun and cloud with isolated flurries. Trace. Low -9 °C, High -2 °C. Wind light to 20 km/h. Freezing level: 1900m

Friday: A mix of sun and cloud. Low -7 °C, High -3 °C. Freezing level: 1900m

Terrain and Travel Advice

  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Avoid exposure to overhead hazards when solar radiation is strong.
  • Uncertainty is best managed through conservative terrain choices.
