Points saillants

The great skiing continues!

We have broken out this forecast region due to the deeper snowpack and lower likelihood of triggering the deep persistent layer for Yoho and Kootenay.

Alpine observations for our forecast are limited.

    Moderate winds are creating wind slabs in alpine terrain. Watch for these as you transition into wind-affected terrain.

    The natural avalanche cycle on this layer has ended. Be wary of shallow areas, as this has been where the bulk of recent large avalanches have started, going from thin to thick.

Avalanche Summary

A few explosive triggered avalanches up to size 2 at the ski hills today, otherwise no new or reported avalanches today

Snowpack Summary

Moderate winds may develop isolated windslab lee alpine features. Surface snow has some surface hoar development, lingering suncrust on steep solar aspects and 20-30cm settled snow in sheltered areas.

There is 40-80 cm over the Dec 15 melt-freeze crust (which is present to 1800-2000 m), 80-160 cm over the November facet/crust interfaces, and, in thinner snowpack areas, facets at the base.

Treeline snow depths range from 100-200+ cm.

Weather Summary

Thurs night: Mainly cloudy. Alpine temperature: Low -7 °C. Ridge wind west: 15 km/h.

Friday: Cloudy with sunny periods and isolated flurries. Alpine temperature: High -7 °C. Ridge wind southwest: 20 km/h.

Saturday: Mainly cloudy with scattered flurries. Accumulation: 5 cm. Alpine temperature: Low -8 °C, High -3 °C. Ridge wind southwest: 20 km/h gusting to 45 km/h.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.
