In sintesi

Expecting a cool, breezy Easter Weekend with scattered flurries.  The snowpack is stronger but the weak faceted base is still lurking.  Remember this when assessing your travel plans.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3
    Cornice failure is hard to predict.  Wise to give them a wide berth.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–4
    The deep instability could be triggered by large loads such as a cornice failure or a surface avalanche. Human triggering is most likely from shallow spots or on steep unsupported slopes.

Weather Forecast

Light flurries expected until Sunday with potential accumulation of 15 cm scattered through the forecast area. Winds increasing to moderate from the west.  Freezing level falling into the weekend.

Snowpack Summary

Grabby melt freeze crust, solar aspects. Dryer surface snow on polar aspects over a solid mid-pack bridging the weak base above 2000m. The base is a combination of weak facets and depth hoar mixed around a Nov rain crust. A consistent melt-freeze cycle is occurring below tree line. Snowpack has cooled at tree-line and above.

Avalanche Summary

No new avalanches reported on Maligne patrol.

Confidence

Timing or intensity of solar radiation is uncertain on Sunday
