Kernpunkte

Spring conditions. Watch for alpine wind slabs and loose wet avalanches in the afternoon. Start early, finish early.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–1.5

    Lingering wind slabs remain at upper elevations.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Very Likely
    Größe
    1–2

    Higher freezing levels and lots of solar radiation will result in loose wet avalanches out of steeper terrain.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

Sunshine patrol observed two wind slabs in the surrounding backcountry, the larger a size 2, triggered by a cornice. Lake Louise patrol reported a natural size 1.5 loose wet avalanche at treeline in closed terrain.

Snowpack Summary

North aspects hold previously wind-affected dry snow. On solar aspects, a crust exist up to ridgetop. With continued daytime heating over the next few days, solar aspects and lower-elevation snowpack will weaken and break down. The lower snowpack is generally well settled.

Weather Summary

Forecast models show another sunny afternoon with warm temperatures. Valley highs near 11, ridge temperatures near 0. Westerly ridge top winds remain strong.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Wind slabs are isolated, but may remain reactive.
