In sintesi

Watch for reactive wind slabs at higher elevations, especially where the snowpack is thin or variable.

Problemi valanghivi

  • Wind Slabs

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

    Reactive wind slabs may still be present in steep, exposed terrain at higher elevations.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely
    Dimensione
    1.5–2.5

    Use extra caution in areas with a thin, uniform snowpack (less than 100 cm). These areas are inherently weak, with heavily faceted snow and crusts closer to the surface, making them easier to trigger.

Confidence

High

  • Confidence is due to a stable weather pattern with little change expected.
  • Uncertainty is due to the complexity of the snowpack’s structure.

Avalanche Summary

On Wednesday, a naturally triggered size 2.5 slab avalanche was observed near Golden, likely due to warming alpine temperatures and strong solar input. The slide released on a steep, wind-loaded, ridgetop slope with a generally shallow snowpack. See MIN report here.

A size 1.5 skier-triggered avalanche occurred near Panorama on Wednesday in a very shallow area (~50 cm deep), likely failing on a layer of facets. See MIN report here.

Snowpack Summary

The upper snowpack continues to settle and strengthen. Light snow beginning Saturday morning will gradually bury a variety of old surfaces, including surface hoar in wind-sheltered terrain and a sun crust on steep south-facing slopes.

In the mid-snowpack, a melt-freeze crust exists that was buried in mid-December. This layer is most prevalent at treeline elevations and below.

The lower snowpack consists of a thick melt-freeze crust, with weak faceted snow and/or depth hoar near the ground in areas.

Snow depths vary widely across the region, averaging roughly 100 to 200 cm at treeline.

Weather Summary

Friday Night
Mostly cloudy. Trace amounts of snow. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Saturday
Mostly cloudy. 2 to 5 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -3 °C.
Sunday
Mostly cloudy. 2 to 8 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -3 °C.

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

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Carefully evaluate steep lines for wind slabs.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
