Regions

Dogtooth, East Purcell, West Purcell.

Snow and wind may form new slabs at higher elevations. Assess for the bond of the snow prior to exposing yourself to high-consequence terrain.

Confidence

Moderate

  • We are uncertain due to the track and intensity of the incoming weather system.

Avalanche Summary

Explosives broke off chunks of cornices on Monday. We haven't received recent reports of slabs being pulled below the falling cornices.

Looking towards Wednesday, riders could trigger newly formed wind slabs at higher elevations. Use caution entering steep, lee terrain features.

Please consider submitting a MIN to let us know what you're seeing out there.

Snowpack Summary

Around 10 to 25 cm of new snow may accumulate by Wednesday afternoon above 1500 m, while rain falls at lower elevations. The snow will be blown around by strong southwest wind, which may form wind slabs in lee terrain features near ridgetop. This new snow sits on moist snow or a hard melt-freeze crust.

A thick crust from mid-March is 30-60 cm deep, which extends up to about 2400 m. Near Invermere, a weak layer of facets may be found above this crust.

Facets are found near the bottom of the snowpack in shallow alpine snowpack areas. The lower snowpack is strong in deep snowpack areas.

The snowpack continues to melt at lower elevations.

Weather Summary

Tuesday Night
Mostly cloudy. 5 to 10 cm of snow with local amounts up to 20 cm possible. 50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mix of sun and clouds with isolated flurries for northern areas around Golden. Mostly cloudy for southern areas around Invermere with 10 to 15 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 1500 m.

Thursday
Morning clouds then a mix of sun and clouds. 5 to 15 cm of snow with local amounts up to 25 cm possible. 20 km/h northwest ridgetop wind. Treeline temperature -5 °C. Freezing level rising to 1600 m.

Friday
Mix of sun and clouds with isolated flurries. 1 to 2 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -5 °C. Freezing level rising to 1600 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Investigate the bond of the recent snow before committing to your line.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
