Lo esencial

Look for signs of instability and be prepared to step back.

There is some uncertainty in how the snowpack will react to above freezing temperatures in the alpine.

Problemas de aludes

    Southwest winds have formed reactive wind slabs in lee terrain. These slabs could remain reactive to riders where they overlie facets or surface hoar.

  • Loose Wet

    Solar input and an above freezing layer could result in wet loose avalanches in the alpine.

Avalanche Summary

No new avalanches have been reported in the past few days.

Snowpack Summary

Previous southwesterly winds have redistributed recent new snow into wind slabs. The snow surface may become moist on steep south facing slopes in the afternoon.

A layer of surface hoar may be found down 10 to 30 cm in sheltered terrain.

A thick melt-freeze crust is found down 50 to 100 cm. this layer is not currently a concern but may be after being impacted by warm temperatures for a prolonged period.

Weather Summary

Tuesday Night

Mostly clear with no new snow expected. 5 to 15 km/h outflow wind. Above freezing layer above 1400 m.

Wednesday

Clear skies with no new snow expected. 5 to 20 km/h outflow wind. Above freezing layer above 1400 m.

Thursday

Clear skies with no new snow expected. 5 to 20 km/h outflow wind. Treeline temperature -1°C.

Friday

Clear skies with no new snow expected. 20 to 30 km/h southeast alpine wind and 10 to 20 km/h outflow wind at valley bottom. Treeline temperature -4°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Be alert to conditions that change with elevation and sun exposure.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
