In sintesi

Spring Conditions. Forecast new snow and wind will bring back that winter feeling in the mountains. Watch for new wind slabs that may not bond to the old hard surface.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    Forecast new snow and wind may develop new wind slabs in the alpine and at treeline. New wind slabs may not bond well to the old surface crust.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–5
    Forecast cloud, light snow, and cooler temperatures may reduce the likelihood of natural cornice falls.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Forecast cooler temperatures and cloud cover should reduce the likelihood of loose wet avalanches. Lower elevations may be reactive during the heat of the day.

Weather Forecast

Moderate southwest winds overnight with light snow and freezing levels around 1700 metres. Moderate southwest winds on Wednesday with light snow and freezing levels close to 2000 metres. A mix of sun and cloud on Thursday with light northerly winds and freezing levels climbing up to 2200 metres. Mostly clear on Friday with light southerly winds and freezing levels to 2500 metres.

Avalanche Summary

No new avalanches reported.

Snowpack Summary

Forecast new snow, wind, and cooler temperatures will bring back winter to higher elevations for a day or two. Expect the old surface to re-freeze overnight and some new wind slabs may form in the lee of southwest winds. These new wind slabs may not bond well to the old hard surface. Surface crusts may break down rapidly if the sun comes out, especially on steep slopes with direct sun exposure.
