Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3
    Wind slabs may be lurking near, or well below, ridge crests. Conditions are highly variable, so be alert to hollow, drummy sounds and changes in the feel of the snow as you travel.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3
    Unusually warm alpine temperatures may weaken surface snow and lead to loose wet avalanches.

Confidence

Fair - Due to the number of field observations

Weather Forecast

High pressure, dry conditions and very warm alpine temperatures are expected to continue until Monday. Light snow is expected to begin late Monday and continue on Tuesday. At this stage, only a few cm are expected. Confidence in the intensity and timing of this system is low.For more details check out avalanche.ca/weather

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

There is anywhere from 30-150 cm on the ground. Recent northerly outflow winds have scoured upwind slopes back to a firm crust, and created wind slabs on lee aspects. The snowpack is highly variable across different aspects and elevations.Wind slabs could be triggered by the weight of a person, especially where they overlie surface hoar, crusts or facets. The other big story is unusual warming at alpine elevations, which may weaken surface layers, or even wake up deeper snowpack weaknesses. Id take a cautious approach to big/ exposed terrain until winter temperatures return to normal.
