Lo esencial

Sunshine and soaring freezing levels throughout the week will elevate the avalanche danger. Cornices are BIG and when they fail there is the potential to trigger large avalanches on deeply buried weak layers.

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

Confidence

Low - 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 when they fail there is the potential to trigger large avalanches on deeply buried weak layers. Lingering wind slabs may still be reactive to human triggers on leeward slopes below ridgetops. Below the surface there are 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.
