    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    Forecast sunny breaks may promote ongoing loose wet avalanche activity. Warming and solar radiation may also trigger destructive cornice falls.

Avalanche Summary

Wind slab triggering may be possible over the weekend. Loose wet avalanche to size 2 were also observed in steep, below treeline terrain. Forecast sunny breaks may promote ongoing loose wet avalanche activity.

Confidence

Fair - Due to the number of field observations

Weather Forecast

Expect a mix of sun and cloud for the forecast period with light flurries possible on Monday evening. Winds should remain generally light with daytime freezing levels sitting at about 1500m.

Snowpack Summary

Light accumulations from Friday may now exist as a soft wind slab in high elevation lee terrain. The new snow overlies older wind slabs, crusts and wind-scoured surfaces. Weaknesses buried in the upper snowpack may include hard crusts and/or weak facet crystals. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile. Below treeline, the snow is in a spring melt-freeze cycle.
