Regions

Kananaskis.

The sunny skies, strong solar effect and warming trend may cause localized instabilities. Particularity on the stepper south aspects. Other than that, the skiing is reasonable with a well settled snowpack.

Confidence

Good

Weather Forecast

A front will be moving into the area which will bring warmer temps over the next few days. Another clear day is on the books for tomorrow with light winds from a variety of directions. Daytime highs will approach -3 at 2000m. Needless to day, no snow is expected for some time.

Avalanche Summary

A few very isolated loose dry avalanches out of steep cliff terrain.

Snowpack Summary

10-12 cm of new snow in the last 48hrs has freshened up the skiing in many areas. There is some surface hoar growth in open areas, but nothing serious or widespread just yet. In general the snowpack is quite well settled and stable for this time of year. The snow depth at treeline varies from 60-100cm. At the Burstall parking lot there is 68cm of snow on the ground.

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.
