Highlights

New snow, strong winds and rising freezing levels will create dangerous avalanche conditions.

Avoid avalanche terrain.

Avalanche problems

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1.5–2.5

    New snow and strong southwest wind will build reactive storm slabs through the day.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1–2.5

    Rising freezing levels will destabilize the new storm snow, potentially triggering large, destructive avalanches.

Confidence

Moderate

  • Uncertainty is due to the timing, track, & intensity of the incoming weather system.
  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

A natural avalanche cycle is expected to occur throughout the duration of this storm.

Large avalanches have been reported running from the alpine into below treeline elevations in the Skeena River corridor. Details are limited at this time.

Up to 50 cm of new snow, significant precipitation in the coming days, and rising freezing levels will keep avalanche danger elevated.

Snowpack Summary

30 to 50 cm of snow has fallen over the past 2 days, accompanied by strong southwest winds. This new snow has fallen on faceted snow from the recent cold weather. The new snow is not expected to bond well to the previous faceted surface.

Last week, more than 100 cm of heavy snow fell, strengthening the snowpack and reducing the likelihood of triggering older layers from early December (which include buried surface hoar and crusts).

Snowpack depth is up to 350 cm at treeline.

Weather Summary

Sunday Night
Cloudy. 10 to 30 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Monday
Cloudy. 10 to 20 mm of precipitation as snow or rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Tuesday
Cloudy. 10 to 40 mm of precipitation as snow or rain at treeline. 60 km/h south ridgetop wind. Treeline temperature 0 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
