Highlights

Wind deposits ranging in size and sensitivity continue to be our greatest concern. Evaluate snow and terrain carefully, be suspect of leeward catchment zones on all aspects and be aware of terrain features that increase the consequences of avalanches.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2.5

    Recent field observations have highlighted copious amounts of blowing snow in exposed areas and along ridgetops due to our current north winds. Resulting wind slabs are likely to be reactive. Older more stubborn wind deposits from our last loading event may still be possible to find. Wind slabs will be most concerning near and above treeline and they may reside on all aspects. Be suspect of terrain features that encourage drifting such as the leeward sides of ridgelines, gully features, and cross-loaded depressions.  Use clues such as blowing snow, stiff and hollow feeling snow, uneven snow surfaces, and recent cornice growth to identify areas with recent deposits.

  • Loose Dry

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    Recent cold temperatures have kept surface snow soft and unconsolidated.  Loose surface sluffs may have the potential to entrain enough snow to be concerning on steep slopes in sheltered areas near and below treeline. Loose-dry avalanches will be most concerning in areas with terrain features that elevate the consequences of an avalanche. This may include road cuts, gully features, mid-slope depressions, or cliff bands.

Avalanche Discussion

Clearing skies during the day yesterday provided the first views of our newly painted winter wonderland as well as some recent avalanche activity that likely occurred during the last loading event. In addition to avalanche concerns today, the backcountry enthusiast may be faced with additional travel concerns. Recently formed wind board in exposed areas and thin melt freeze crusts in sheltered sun-exposed areas may make for some variable and challenging surface conditions. In addition, roads are still being cleared and road crews would appreciate your patience as they work to open parking areas and trailheads. Enjoy the clear skies today, more snow is on the menu for tomorrow!
