Kernpunkte

We are expecting a rapid warming trend tomorrow afternoon. This will be coupled with clear skies. The sun will pack a punch!

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–2.5
    Assess steep, unsupported terrain carefully. Especially around ridges.

  • Loose Wet

    Steep, rocky terrain will hold the sun's heat and cause loose wet avalanches to become a concern. They could be a problem in themselves, but they could also act as a trigger for slabs.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–3.5
    Cornices could start to fail if they see a lot of sun. These kinds of large triggers could cause the deep layers to fail.

Weather Forecast

Temps tonight will fall to -12 at 2200m with light westerly winds. Tomorrow will see the freezing level rise to 1900m, with treeline temps settling at -4. The sun will be shining with the odd cloudy period. Expect strong solar input on south & southwest slopes. Winds will diminish as the warm spell approaches.

Avalanche Summary

Loose dry & loose wet avalanches were noted today at the lower elevations. They came out of steep rocky terrain where the sun had a big impact.

Snowpack Summary

Today is the first day in a long time that temperatures on the Spray went above 0C. The freezing level reached 2200m for a short period this afternoon. While not a huge input of heat, many solar aspects now have a surface crust. The alpine and treeline windslabs are improving with the moderate temperatures. The relative warmth is helping the various layers bond. Despite the rising temps, we did see a few cm of new snow today from flurries blowing through the area.
