Regions

Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

Strong winds and new snow overnight and into Friday will likely trigger a natural avalanche cycle.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

Avalanche Summary

No new avalanche activity was observed on Thursdays field trip.

Snowpack Summary

5cm of recent snow is being moved around by the strong to extreme winds adding more load to the current windslabs that are widespread throughout the forecast region. 40-70cm of snow is overlying the Feb 14th layer which consists of suncrust, surface hoar and old/or hard wind slabs.

Windslab development is ongoing with strong to extreme SW-W winds. As more snow falls these windslabs will continue to get more reactive. Pay close attention to snow amounts over the next 24hrs.

Weather Summary

15cm or so of snow is forecast to fall overnight and into friday with strong to extreme winds out of the SW. Temperatures will be around -5C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.

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.
