Points saillants

The freezing levels are rising and the overnight lows are climbing. This spring heat will quickly increase the avalanche hazard.Avoid large slopes with solar aspects.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1.5–2.5
    Lots of wind slabs in the Alpine and along ridgelines at Treeline. Steep and unsupported terrain should be considered suspect.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Likely
    Taille
    1–2
    Steep, rocky terrain will hold the sun's heat and cause loose wet avalanches to become a concern by midday. They could be a problem in themselves, but they could also act as a trigger for slabs.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely
    Taille
    2–3.5
    Cornices could start to fail if they see a lot of sun. These kinds of large triggers could cause the deep layers to fail.

Snowpack Summary

Extensive wind slabs in the alpine that reach down to isolated areas of treeline and cross loaded features. Moist snow on steep solar aspects and on all aspects up to 2200m that are not shaded. Good skiing was still found on shady aspects in the trees.

Confidence

Moderate -

Weather Forecast

Monday is forecast for another sunny day with the freezing level going up to 2400m. Winds are suppose to be light out of the West. Tuesday and Wednesday will see more warming and the freezing level should reach 2900m.

Avalanche Summary

Several loose wet avalanches up to 1.5 on solar aspects.Several slabs released at all elevations on NE to SE aspects up to size 2
