Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Watch for newly formed wind slabs as you get above the trees.

The best and safest riding will be in areas sheltered from the wind.

Avalanche Summary

No new avalanches were reported on Thursday.

On Wednesday there were reports of small dry loose avalanches. No slabs were reported.

Data is very limited in this region. Please submit a report on the Mountain Information Network. Even a simple photo is a huge help to other backcountry users.

Snowpack Summary

Last night's snowfall of 10 to 20 cm brings totals to 30 to 50 cm of snow above a melt-freeze crust from early December. Lower amounts will be found on the eastern slopes. At upper elevations, wind has likely redistributed snow to lee features.

There are no deeper layers of concern.

Data is very limited in this region.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.

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.
