In sintesi

Danger will start low in the morning and steadily increase with daytime warming. Temperatures are expected to spike significantly on Tuesday. 

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Wind slabs have formed on lee slopes and cross loaded features at alpine and exposed tree line elevations.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione

    Natural cornice failures are being observed daily. Pay attention to what is above you and avoid cornice exposed slopes.

  • Loose Wet

    • Alta quota

    Probabilità
    Possible - Likely
    Dimensione
    1–3
    As temperatures warm up so does the potential for loose wet avalanches. It may be enough to trigger deeper basal layers increasing the consequences.

Weather Forecast

Sunday into next week will be sunny and warm. Expect freezing levels to rise significantly next few days with less recovery every night.

Snowpack Summary

Strong Southwesterly winds have created pockets of windslab and scoured any exposed areas at upper elevations. Weak basal facets are bridged by a strong mid-pack in most areas at treeline and above.

Avalanche Summary

Natural cornice failures continue and many more are waiting their turn to fall. Intense solar radiation likely to initiate afternoon wet loose avalanche conditions.

Confidence

Timing or intensity of solar radiation is uncertain
