Regions

East Kakwa, Tumbler.

Tread lightly...

The snowpack is shallow with plenty of early season hazards just below the surface. Your A-arms will be nervous out there.

Confidence

Moderate

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 20 to 50 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

Sunday Night

Mostly clear with trace amounts of new snow expected, south alpine wind 40 to 60 km/h, treeline temperature -3°C.

Monday

Mostly cloudy with trace amounts of new snow expected, south alpine wind 40 to 70 km/h, freezing level rising to around 1400 m.

Tuesday

A mix of sun and cloud with a few cm of new snow expected by early morning, southwest alpine wind 40 to 70 km/h, freezing level around 2000 m.

Wednesday

A mix of sun and cloud with no new snow expected, southwest alpine wind  20 to 40 km/h, freezing level falling to 1100 m.

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.
