Wind slabs forming at ridge crests and open TL features reactive to skier traffic. Expect hazard to increase if forecasted snow checks-in on Sunday!
Weather Forecast
Temperatures to remain cool over the weekend. A warm moist system expected in the region overnight Sunday. Bringing with it warmer temps and potentially up to 30cm of snow.
Snowpack Summary
Generally a strong, and supportive early winter snowpack exists with depths ranging from 30 to 100+ cm depending on aspect and exposure to wind. Wind effect on recent snow isolated to exposed slopes and ridge tops in the alpine. New snow remains well preserved on sheltered aspects.
Avalanche Summary
No new natural activity reported from a field team. Climbers should still remain vigilant as even triggering a small avalanche in a gully feature or above cliffs can have severe consequences.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Sunday
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.
