Avalanche Summary
Several size 1-1.5 loose dry avalanches were reported over the weekend. See this MIN report for an example here. On Saturday, a size 2 wind slab avalanche was triggered by a skier north of Pemberton. The avalanche occurred on a southwest aspect at 1850 m.
Snowpack Summary
8-15 cm new snow fell on Monday night, with highest amounts recorded along the Duffey. Winds shifted to the north during the storm, potentially creating some unusual wind slabs on south-facing slopes. Beneath this recent snow you may find hard wind-affected snow at higher elevations, soft and faceted snow in shaded and sheltered areas, and melt-freeze crusts on southerly slopes. The middle and lower snowpack is generally well-settled.
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.
