Avalanche Summary

Early season, observations are limited. Thanks for sharing your observation through the Mountain Information Network if you head out.

No new avalanches have been observed or reported. Please share your observations at [email protected] or via the Mountain Information Network.

Snowpack Summary

There is 5 to 15 cm of snow over the December 11 crust. 10 cm of facets is present between the two crusts. The November 28 crust is 20-25 cm deep and rests on mixed layers of melt-freeze snow. The height of the snowpack varies from 30 to 70 cm, depending on altitude and wind loading.

Weather Summary

Synopsis: Temperatures will remain cold or below seasonal normal, between -5 and -15 over the next few days, with moderate to strong winds from the west. The northern sector of the forecast area could receive some snow due to sea effect.

Wednesday evening and night: Cloudy. 2 to 4 cm of snow. Moderate to strong northwesterly wind, 30 to 50 km/h. Low -15.

Thursday: Alternating sun and cloud. 2 to 4 cm of snow. Moderate northwesterly wind, 30 to 40 km/h. High -9. Low -12.

Friday: Alternating sun and clouds. Wind west, 30 to 40 km/h. High -5.

Saturday: Sunny. Wind northwest, 40 to 50 km/h. High -10.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Carefully evaluate steep lines for wind slabs.

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.
