Snow amounts are expected to stay light on Thursday. Watch out for wind slabs on unusual aspects in exposed areas.
Weather Forecast
WEDNESDAY NIGHT: Flurries with 1 or 2 cm of snow expected.THURSDAY: Light snow, 2-4 cm. Light to moderate southwesterly winds. Freezing level around 1000 m.FRIDAY: Dry with a mix of sun and cloud. Freezing level rising to around 1500 m. Light southwesterly winds.SATURDAY: Dry with a mix of sun and cloud. Freezing level around 1800 m. Light southerly winds.
Avalanche Summary
Small loose wet avalanches were reported on Tuesday on south-facing slopes. There was also a size 1.5 remote-triggered avalanche reported at 1400 m.During the previous storm, there was an avalanche cycle to size 2.5. Operators noted some avalanches showed wide propagations.
Snowpack Summary
Another 15-20 cm new snow added to previous amounts to give storm totals in the range of 30-50 cm. Towards the end of the storm, winds shifted to the north, potentially creating some unusual wind slabs on south-facing slopes. Beneath the recent snow you may find hard wind-affected snow at higher elevations, soft faceted snow in shaded and sheltered areas, and crusts on steep southerly slopes. The middle and lower snowpack is 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.
