Kernpunkte

The clear and warm streak continues. Be aware of day time warming as it will increase the avalanche hazard.

Lawinenprobleme

  • Loose Dry

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–1.5
    Cold temperatures continue to facet the surface snow causing it to loose cohesion. Point release activity will increase with strong solar input on steep S and W aspects at all elevations.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely
    Größe
    1.5–2.5
    The basal weakness (aka depth hoar) is generally dormant; however, these may be possible to trigger in isolated shallow snowpack places.

Weather Forecast

Tuesday: Sunny with cloudy periods. Precip: Nil High -8 C. Ridge wind east: 10 km/h. Freezing level at valley bottom.Wednesday: A mix of sun and cloud with isolated flurries. Precip: Trace Low -16 C, High -5 C. Ridge wind south: 10-25 km/h. Freezing level: 1400 meters.Mountain weather forecast available at Avalanche Canada.

Snowpack Summary

The upper snowpack remains faceted on all aspects. S and W aspects are starting to show signs of solar input. Wind effect in open terrain from previous SW and now N winds. Much of the mid-pack is faceted with some strength and support on skis but not always under foot. The warming trend on Wednesday will destabilize the snowpack.

Avalanche Summary

A field team ice climbing down south today noticed previously baked solar slopes from previous warm days, no new avalanche noted today.

Confidence

Due to the number and quality of field observations
