Regions

East Kakwa, Tumbler.

Stay light...

The snowpack is shallow with many hazards on or near the surface.

Small pockets of wind slab over facets could be found near ridge crests.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Check out this great MIN report from Core Lodge.

The snowpack is shallow, faceted and highly wind-effected. Expect scouring on windward slopes and isolated pockets of deep wind slab over facets near ridge crests on leeward slopes. A crust has formed on the surface below treeline.

Several crusts exist in the mid pack. Isolated pockets of buried surface hoar could be found in sheltered terrain.

Average snowpack depths at treeline are highly variable (20 to 70 cm). Many hazards are on or just below the surface.

Weather Summary

Friday Night

Partially cloudy with trace amounts of new snow expected, west alpine wind 30 to 70 km/h, freezing level falling to valley bottom.

Saturday

Mostly sunny with no new snow expected, southwest alpine wind 25 to 50 km/h, treeline temperature -3°C.

Sunday

A mix of sun and cloud with no new snow expected, southwest alpine wind 25 to 40 km/h, treeline temperature -3°C.

Monday

A mix of sun and cloud with no new snow expected, southwest alpine wind 25 to 40 km/h, treeline temperature -3°C.

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.

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.
