Points saillants

Watch for decreases in stability related to solar radiation as temps warm up.  These decreases will be most apparent on steep solar aspects. 

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely

    Stiff windslabs should be expected in treeline and alpine areas.  Be cautious in thin, steep or unsupported terrain.

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité

    The basal problem of facets and depth hoar will likely persist all winter.  This layer is getting harder to trigger, but will result in a large destructive avalanche if it initiates.

Confidence

Fair - Timing or intensity of solar radiation is uncertain on Saturday

Weather Forecast

Warm temperatures and clear skies will persist through the weekend.  We are in a bit of a holding pattern for new snow at this time...

Avalanche Summary

No new natural avalache activity was observed.

Snowpack Summary

Not much changing out there these days...  The warm temps are helping to settle the snowpack out but the main concern is still for the weak basal facets.  They are becomming harder to trigger but if they do go, it will result in a large avalanche.
