Regions

Kakwa, Tumbler.

A very shallow snowpack exists with numerous hazards present either at or just below the snow surface.

Remember, if the snow is deep enough to ride, it is deep enough to trigger an avalanche.

Confidence

Low

Avalanche Summary

No recent avalanches have been reported. Information from the field is sparse this time of year. Consider submitting a MIN report if you are recreating in the mountains.

Snowpack Summary

The snowpack is very shallow, and below threshold in many areas. Various hazards exist just below the snow surface.

The height of snow at treeline is roughly 50 cm. Snow depths decrease dramatically at lower elevations.

At higher elevations, pockets of deeper, wind-loaded snow may exist and sit atop a weak, facetted layer at the base of the snowpack.

Weather Summary

Friday Night

Mostly clear skies with no precipitation, west alpine winds 40 km/h, treeline temperature -5 °C.

Saturday

Partly cloudy with no precipitation, northwest alpine winds 15 km/h, treeline temperature -5 °C.

Sunday

Mostly sunny with no precipitation, northwest alpine winds 25 km/h, treeline temperature -3 °C.

Monday

Mix of sun and clouds with no precipitation, west alpine winds 60 km/h, treeline temperature -3 °C.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.
  • If it's deep enough to ride, it's deep enough to slide (avalanche).

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.
