Highlights

Small wind slabs may exist in Leeward terrain features.

Use caution as you transition into wind-affected terrain.

Avalanche problems

  • Wind Slabs

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

    Southerly winds have formed wind slabs on lee alpine slopes. These slabs may be more reactive when they overlie surface hoar.

  • Loose Wet

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

    Treeline elevations have seen above-freezing temperatures for multiple days. Until below-zero temperatures return, wet loose avalanches will be possible.

Confidence

Moderate

  • We are uncertain due to variable freezing levels.
  • We are uncertain if precipitation will fall as rain or snow.

Avalanche Summary

Numerous size 1.5 wet loose avalanches were reported in the alpine at the Onion riding area on Wednesday.

Observations are still limited, so be sure to post yours to the MIN if you get out!

Snowpack Summary

A few centimetres of new snow on Friday night will overlie a crust formed by this week's warm temperatures and rain, extending to at least 1800 m.

In the alpine, wind slabs overlie a hard crust that extends up to 2300 m. Surface hoar can be found on this crust in some locations at treeline.

A second layer of facets or surface hoar is buried around 50 to 100 cm deep, and is considered unlikely to trigger at this point.

The mid and lower snowpack have no layers of concern. Snowpack depths are around 150-200 cm at treeline.

Weather Summary

Friday Night
Cloudy. 2 to 4 mm of precipitation as snow or rain at treeline. 40 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1600 m.

Saturday
Cloudy. 5 to 10 cm of snow or rain at treeline. 30 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1400 m.

Sunday
Mix of sun and clouds. 1 to 2 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Monday
Mix of sun and clouds. 1 to 10 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
