Avoid avalanche terrain on Sunday

Travel cautiously on Monday and Tuesday, storm slabs will likely remain rider triggerable.

Confidence

High

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

No new avalanches have been reported at the time of publishing. If you head out in the hills please consider sharing your observations via the Mountain Information Network.

Snowpack Summary

By late afternoon on Sunday up to 30 cm of new snow will likely have fallen in the hills. Overnight snow will be distributed by southerly wind followed by northwest wind during the day on Sunday. Deep deposits of wind drifted snow could be found on all aspects as a result.

Storm snow will overlie a crust/facet combo  that it likely won’t bond well too.

In sheltered terrain the snowpack depth in the hills is around 140 cm .

Weather Summary

Saturday Night
Cloudy. 10 to 15 cm of snow. 50 km/h south ridgetop wind. Treeline temperature -4 °C.

Sunday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Monday
Mix of sun and cloud With  2 cm of snow in the morning, sunny in the afternoon. 30 km/h northwest ridgetop wind. Treeline temperature -12 °C.

Tuesday
Mostly cloudy. 4 to 5 cm of snow. 50 km/h east ridgetop wind. Treeline temperature -12 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy snowfall.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • Carefully manage your exposure to overhead hazards.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
