In sintesi

Freezing levels are rising to above ridgetop and a mix of ran and snow will fall during the forecast period.

Exercise caution on steeps slopes with moist surface snow. Wet avalanches may run bigger and farther with a solid crust underneath to slide on.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Recent strong wind means wind slabs may be found farther downslope than expected.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

One size 2 wind slab avalanche and a few wet loose avalanches to size 1.5 were observed in the past few days.

Snowpack Summary

Strong winds continue to redistribute snow into wind slabs and create widespread wind-affected surfaces. The surface snow is moist to 2000m on all aspects with rising the freezing level. A crust is down 20-40cm and 2-8 cm thick with several other crusts deeper in the snowpack. The mid and lower snowpack is generally well settled with total snowpack depth ranging from 130-220 cm at treeline and in the alpine. 40-120cm below treeline.
