In sintesi

Strong solar radiation may increase the reactivity of recently formed storm slabs.

Avoid steep, sun-exposed slopes when solar radiation is strong.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–3

    Cornices are large, looming, and can trigger large avalanches on the slopes below.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2.5

    Strong solar radiation may increase the reactivity of recently formed storm slabs, especially on steep slopes in the alpine.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–1.5

    Expect sunny skies to trigger wet loose avalanches on sunny aspects.

Terrain and Travel Advice

  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

No new avalanches were reported on Tuesday.

Observations are currently very limited in this region. Please consider submitting a MIN to let us know what you're seeing out there.

Snowpack Summary

20 to 40 cm of recent snow and wind from a variety of directions have formed storm slabs that will be most reactive on lee features at upper elevations.

Below the recent snow is a hard crust that exists on all aspects to at least 2500 m.

The mid and lower snowpack is well settled and strong in most areas.
