Regions

South Rockies, East Purcell, Bull, Elkford East, Elkford West.

Avalanches remain possible where dry snow is available to form fresh wind slabs

Watch for areas without a thick crust at or near the surface, buried weak layers may remain reactive

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

On Saturday, small loose wet avalanches were observed. The previous rain and warm temperatures produced a widespread wet avalanche cycle to size 3.

If you are heading into the backcountry, please consider sharing conditions via the MIN.

Snowpack Summary

A widespread, developing melt-freeze crust exists, extending to mountain top in most areas. Around 15 cm of new snow can be found at upper elevations, redistributed by southwest winds.

Below this, 30 to 50 cm of wet snow sits above a crust (1 to 10 cm thick). Various persistent weak layers may still exist in the top 120 cm of the snowpack - these remain a concern at higher elevations where a supportive surface crust does not exist.

In shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack.

Weather Summary

Sunday Night
Mostly clear skies. 50 km/h west ridgetop wind. Treeline temperature -6 °C.

Monday
Sunny. 50 km/h west ridgetop wind. Treeline temperature -6 °C.

Tuesday
Mix of sun and clouds. 5 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1900 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
