Points saillants

Storm snow is settling but may still be reactive to human triggers.

Continually assess as you travel, and watch for signs of instability, specifically on high, north facing terrain.

    Higher elevations may hold up to 50 cm of drier snow, with deeper and more reactive deposits in wind affected features.

    Fluctuating freezing levels may continue to impact surface snow making wet loose avalanches possible to human trigger.

Avalanche Summary

Numerous human-triggered size 1 storm slab avalanches were reported on Monday.

Going forward storm slabs will likely become less reactive, but currently still need some time to settle.

Confidence

Moderate

  • We are uncertain due to variable freezing levels.

Snowpack Summary

Snow and rain from fluctuating freezing levels has buried previously wind affected surfaces.

Above 1800 m roughly 40 cm of moist snow sits over a crust and facets at treeline and above, and a combination of crust and surface hoar in sheltered features and lower elevations.

The mid/lower snowpack is generally well settled and strong.

Cornices are reported to be large and looming. Be mindful of them overhead or when travelling on ridge tops.

Weather Summary

Monday Night
Cloudy. 1 mm of rain at treeline. 30 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Tuesday
Mostly cloudy. 1 to 2 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2000 m.

Wednesday
Mix of sun and clouds. 1 to 4 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2600 m.

Thursday
Sunny. 50 km/h southwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2900 m.

Terrain and Travel Advice

  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
