Kernpunkte

Use caution around ridge crests and steep rollovers, where wind slabs are most likely to form.

Expect sun-exposed slopes to deteriorate, and avoid steep terrain if snow becomes moist.

    Größe

    Recent wind from various directions has formed isolated wind slabs over various hard surfaces of wind-pressed snow and/or a crust.

    The sun can pack a punch! Use caution on slopes facing the sun and back off if the snow becomes moist and/or wet and weakens. Pinwheels and natural avalanches are your initial signs of instability.

  • Deep Persistent Slabs

    Größe
    2–3

    A faceted lower snowpack presents a persistent slab problem. This basal layer may be triggered by cornice fall or the weight of a rider in shallow snowpack areas or on steep features where the snowpack transitions from thick to thin.

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

In the alpine, up to 15 cm of dry, wintery snow sits above a variety of old snow surfaces. A buried surface hoar layer may remain intact on sheltered northerly terrain and hard wind-pressed surfaces, wind slab, and sastrugi exist on exposed slopes. A melt-freeze crust can be found from 1200 to 1500 m on all aspects but north. This will be firm in the am and may soften by the afternoon.

The lower snowpack is faceted and generally weak, particularly in shallow areas.

Sunday
Mix of sun and clouds. 1 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -5 °C.

Monday
Mix of sun and clouds. 2 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
