Kernpunkte

Sunshine and high freezing levels will increase the likelihood of loose wet avalanches and cornice failures. Minimize exposure to sun exposed slopes when the solar radiation is strong.

    When the sun comes out it will quickly weaken the new snow and cause loose wet avalanches on steep solar slopes.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches were reported in this region. Avalanche reports have been limited due to very few information sources this time of year. If you have been out, please post your observations on the Mountain Information Network (MIN).

Snowpack Summary

Cornices are large and looming. Lingering wind slabs may still be reactive in isolated steep, north facing terrain. This storm snow overlies numerous crusts in the upper 100 cm of the snowpack. The mid-pack is generally well settled and strong.A layer of sugary facets around a crust can be found near the bottom of the snowpack which has been dormant for some time. Large triggers, such as a falling cornice, or a major warm-up to the snowpack could trigger this layer.
