In sintesi

Avoid exposure to overhead hazards when solar radiation is strong.

Cornice failures may trigger avalanches on the slopes below.

    Strong solar radiation combined with high freezing levels will increase the likelihood of wet avalanches.

Confidence

Moderate

  • We are uncertain about how the snowpack will react to the forecast weather.

Avalanche Summary

On Wednesday, several naturally triggered size 1 wet loose avalanches were reported on steep, sunny aspects.

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

Snowpack Summary

Poor overnight crust recovery and strong solar radiation mixed with high freezing levels are increasing the likelihood of cornice failures and wet avalanches.

A hard melt-freeze crust exists to mountain top.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.

Terrain and Travel Advice

  • Avoid exposure to overhead hazards when solar radiation is strong.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
