East Kakwa, Tumbler.

Watch for early season hazards lurking just below the surface.

Avalanche Summary

No new or recent avalanches have been reported in our region. If you do venture out, support your community by submitting a MIN report.

Snowpack Summary

In sheltered areas at higher elevations, pockets of wind-loaded snow sit atop a weak snowpack. Exposed areas have been wind scoured.

At treeline, the height of snow ranges from 40 to 70 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.

Weather Summary

Thursday Night

Mostly clear, no precipitation, alpine winds southwest 10 to 15 km/h, treeline temperature -8 °C.

Friday

Mix of sun and cloud, no precipitation, alpine winds southwest 20 to 30 km/h, treeline temperature -8 °C.

Saturday

Mostly sunny, no precipitation, alpine winds southwest 25 to 45 km/h, treeline temperature -9 °C.

Sunday

Cloudy with some sunny periods, trace accumulation, alpine winds southwest 40 km/h gusting to 70, treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

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.
