In sintesi

It's still warm at higher elevations, so be cautious of overhead hazards and large terrain.

It is uncertain how the continued warmth will affect the snowpack so watch for signs of instability

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–3

    Past winds have been strong and from the southwest, it may be possible to find wind slabs lingering in lee terrain.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely
    Dimensione
    2–3

    A buried layer of surface hoar on a crust is particularly concerning in the north of this region.

    This layer may become more reactive as the warm air lingers.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–2.5

    Steep south aspect terrain will begin to destabilize when temperatures rise and the sun is out.

    Consider avoiding these features during daytime warming.

Confidence

Moderate

  • Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.

Avalanche Summary

January 17

  • No new avalanches reported but observations are limited. Consider posting to the MIN if you are out in the mountains!

January 16

  • A large (size 2) natural cornice triggered avalanche was reported on a northwest aspect.

January 14

  • A natural avalanche cycle was reported, with small (size 1) wet avalanches at lower elevations and large (up to size 2.5) wind or persistent slab avalanches in the treeline and alpine.

Snowpack Summary

80 to 150 cm of snow fell early last week accompanied by strong southerly winds at upper elevations and has settled from warm temperatures at all elevations.

In sheltered ares at lower elevations this snow is possibly resting on surface hoar.

On steep south aspect slopes a surface crust is present in the alpine.

At treeline and below, rain and warm temperatures may have affected the surface snow. As temperatures cool this warm and wet snow has formed a stout melt freeze crust.

The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 150 cm to 250 cm.

Weather Summary

Sunday Night
Clear skies. 30 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 3300 m.

Monday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2800 m.

Tuesday
Sunny. 10 km/h east ridgetop wind. Treeline temperature -1 °C with an above freezing layer between 1500 m and 2600 m.

Wednesday
Mostly sunny. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C. with an above freezing layer between 2000 m and 2300 m.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Keep in mind that human triggering may persist as natural avalanches taper off.
