Highlights

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

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    Loose snow will be impacted by wind in open areas. Check for wind slabs in steep and convex slopes at higher elevations or where new snow covers surface hoar.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely
    Size
    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

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

On Monday, numerous natural and human triggered avalanches were reported. These avalanches were mostly size 1 with one larger size 2. These avalanches likely involved a surface hoar layer down 20 to 30 cm.

Snowpack Summary

20 to 30 cm of recent accumulated storm snow covers 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

Thursday
Mix of sun and clouds. 3 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Friday
Mix of sun and clouds. 1 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -6 °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.
