Kernpunkte

In other forecast regions deep persistent weaknesses are finally becoming active, causing some large avalanches. Keep this in mind when evaluating larger features.

    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Recent snowfall with moderate winds and rapid settlement from continued warm temperatures will make soft slab and windslab releases likely from lee features in the alpine and at treeline.

    Large cornices or surface avalanches are the likely trigger.

Weather Forecast

Continued light precipitation is forecast for the next several days with freezing levels rising each day to near 2000m. Light to moderate southwest winds will continue to build windslab and cornice growth on typical lee features.

Snowpack Summary

5cm in the north of the Forecast zone and up to 10cm in the icefields area arrived with light to moderate southwest winds. This new snow arrived with warm temps and we expect windslab development in lee features and continued cornice build up. New snow loading may overload some existing windslabs to produce natural avalanches to size 2.

Avalanche Summary

No new avalanches reported, but limited visibility today for higher elevation areas.

Confidence

Forecast snowfall amounts are uncertain
