Avalanche Forecast
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. Â
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.Â
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.
Avalanche Problems
Wind Slabs
Watch for thin wind slabs in exposed terrain, Recent winds have varied in direction so assess for wind slab on all aspects. Sensitivity to triggering could be greater where wind slabs have formed over a crust.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
