In sintesi

If you are finding dry, soft snow, use caution around ridgetops and rollovers where triggering a wind slab is possible.

Expect to find a newly formed surface crust in some places.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    Dimensione
    1–1.5

    Pockets of wind slab may linger in shaded, open terrain below ridgetops, and cross-loaded features.

Confidence

Moderate

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

Avalanche Summary

On Sunday, northeast of Kamloops, a few small (size 1), solar triggered loose wet avalanches were reported in steep terrain.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

There may now be a frozen surface crust on all aspects due to recent high freezing levels. This is even more likely on steep slopes that face the sun.

10 to 20 cm of settling snow overlies wind-affected surfaces or old settling storm snow. Recent strong wind has scoured south-exposed slopes and alpine features.

There are a couple of layers of surface hoar/facets or a crust that may be buried 20 to 45 cm deep. These layers have not resulted in recent avalanches, but they may become active in isolated areas where a sufficient slab forms overtop.

The remainder of the snowpack is well consolidated.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
