In sintesi

Sun and warmth will likely increase the avalanche danger.

Plan your route to avoid any exposure to overhead cornices.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    2–3

    Cornices are large and overhanging. Avoid travelling underneath them.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2.5

    West of Invermere, a layer of sugary facets on a crust which is 20 to 60 cm deep has produced a few avalanches. Near Golden, it lacks the weak facets and hasn't yet been a problem.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2

    As temperatures rise and the sun comes out, wet loose avalanches become more likely.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

Large cornice failures continue every day; the warm temperatures are making them more likely to fall.

Small wet loose avalanches have begun and are likely to become more widespread with sun and warmth.

Snowpack Summary

A thin crust has formed on south-facing terrain from recent solar radiation and overnight refreeze. On shaded aspects, 10 to 15 cm of soft snow survives.

Below this, 20 to 60 cm overlies a thick crust from the March atmospheric river, which extends up to at least 2200 m. Near Invermere, weak sugary facets have been seen on this crust.

Various persistent weak layers may still exist in the top 150 cm of the snowpack and in shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack. Large triggers, like falling cornices, may be able to trigger these layers at upper elevations where the crust below the recent snow is thin or absent.

Terrain and Travel Advice

  • Start your day early and be out of avalanche terrain during the heat of the day.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avoid travelling on slopes below cornices.
