Kernpunkte

Avalanche danger will increase through the day with warming and sun—plan your day accordingly.

Dry, wintery snow may persist at higher elevations, along with reactive wind slabs.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2.5

    On north-facing and high-alpine slopes where dry, loose snow may persist, wind slabs remain possible.

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1.5–2.5

    Cornices will weaken with daytime warming and solar input.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–2

    Wet loose avalanches are most likely during periods of direct solar input and as temperatures rise later in the day.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Numerous loose wet avalanches (up to size 1.5) were reported across the region on Saturday. A few recent, large cornice failures were also observed in the Terrace area.

Snowpack Summary

A widespread surface crust is likely to form overnight at treeline and above, except in high-alpine terrain (above ~2000 m), particularly on north aspects, where dry, wind-affected snow may persist.

Below treeline, limited overnight refreezing is likely to result in a moist or isothermal upper snowpack. With daytime warming and a chance of sun, the upper snowpack will weaken throughout the day.

Weather Summary

Sunday Night
Mostly cloudy. 30 km/h west ridgetop wind. Treeline temperature 1 °C. Freezing level 1500 m.

Monday
Mostly sunny. 40 km/h west ridgetop wind. Treeline temperature 1 °C. Freezing level 1500 m.

Tuesday
Mostly sunny. 30 km/h northwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1400 m.

Wednesday
Mostly sunny. 40 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Avalanche danger will increase as the surface crust breaks down.
  • Think carefully about your exit plan from the backcountry because avalanche danger is expected to increase throughout the day.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
