Regions

South Rockies.

Carefully assess the wind slab hazard as you gain elevation. Wind slabs could be touchy due to the underlying crust.

Confidence

Low - Uncertainty is due to the track & intensity of the incoming weather system.

Weather Forecast

Sunday night: flurries bringing trace amounts of new snow. Moderate to strong southwest winds and a low of -3 at 2000 m.

MONDAY: Mostly cloudy with around 5 cm of new snow expected. strong southwest wind and freezing level around 2000 m.  

TUESDAY: A mix of sun and cloud with light flurries bringing trace amounts of new snow. moderate west wind and freezing level around 1500 m.

Wednesday: Sunny with no new snow expected and light southerly winds. Freezing level rising to 1900 m.

Avalanche Summary

No new avalanches have been reported in the region in a few days. We suspect small rider triggerable wind slabs could be found in exposed terrain.

Snowpack Summary

New wind slabs could be found in exposed alpine and treeline terrain. A crust exists on all aspects to around 2500 m and likely to mountain top on sun affected slopes. This crust will likely become moist at lower elevations as the freezing level rises. 

Below 1700 m, the snowpack has been reported as being moist to ground, and is becoming isothermal.

Terrain and Travel

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Wind slabs may be poorly bonded to the underlying crust.

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.
