In sintesi

Cooling temperatures are reducing the likelihood of triggering large persistent slab avalanches.

Avoid steep or convex terrain features with a shallow or thin-to-thick snowpack.

    A crust with weak facets above is down 40 to 130 cm. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places to trigger this layer.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported on Thursday, but data is very limited in this region.

If you go out into the backcountry, please consider posting your observations on the Mountain Information Network.

Snowpack Summary

0 to 5 cm of recent snow overlies predominantly crusty surfaces.

A widespread crust with sugary facets above is buried 40-130 cm deep. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places to trigger this layer. However, when a thick surface crust is present, human triggering this layer is unlikely.

Weather Summary

Friday night

Partly cloudy. 5 to 10 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Saturday

Cloudy with isolated flurries, 0 to 5 cm snow. 10 to 20 km/h northeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1800 m.

Sunday

Sunny. 30 to 40 km/h north ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Monday

Mix of sun and cloud. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1700 m.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Cornice failure may trigger large avalanches.
