Regions

North Rockies, Sugarbowl, McGregor, Pine Pass, Renshaw, Robson.

Wind-loaded areas hold the most snow but they also have the highest avalanche risk at this time.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported in the region. Thanks to all those who have submitted a MIN report already this year, all the information is really helpful for forecasters.

Snowpack Summary

In Torpy and Kakwa area, 5 to 10 cm of new snow overlies wind-loaded pockets of snow in sheltered areas and scoured surfaces in exposed areas.

At treeline, the height of snow ranges from approximately 50 to 80 cm. As you descend to lower elevations, snow depths decrease significantly.

The snowpack at all elevations is very shallow and contains many potential hazards just beneath the snow surface.

Data is very limited at this time. If you are recreating in the mountains please consider submitting a MIN report.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
  • Be especially cautious as you transition into wind affected 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.
