Regions

Banff Yoho Kootenay, Banff, East Side 93N, LLSA, West Side 93N.

Clear skies will continue, and the ski quality has improved, but the avalanche hazard is still elevated.

Be aware of what is above you, especially where the wind may be present.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

A widespread natural avalanche cycle up size 3 has occurred in the last 24-48 hours and is slowly tapering off.

Snowpack Summary

15-40 cm has fallen in this region over the last 72 hours, with the highest amounts along the divide North of Lake Louise. Strong to extreme SW/W winds have created reactive wind slabs at ridgetop and in wind-exposed areas. In some thin areas, there are facets near the base, but overall, the snowpack is stronger than usual.

Weather Summary

Tonight: Clear. Alpine temperature: Low -7 °C. Mostly light ridge wind occasionally gusting to 40 km/h.

Sunday: Sunny. Alpine temperature: High -3 °C. Mostly light ridge wind occasionally gusting to 40 km/h. Freezing level: 2000 meters.

Monday: A mix of sun and cloud. Alpine temperature: Low -4 °C, High -1 °C. Mostly light ridge wind occasionally gusting to 50 km/h. Freezing level: 2200 meters.

Terrain and Travel Advice

  • Avoid areas with overhead hazard.

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.

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
