Thursday: 5-10 cm new snow with more in the south than the north. Freezing level around 500 m. Strong southeasterly winds.Friday: Up to 5 cm new snow. Freezing level around 500 m.

On Tuesday, there was a size 2 natural wind slab avalanche reported from a north aspect alpine slope. There were also several small (size 1), thin soft slab avalanches on recently wind-loaded features. A large (size 3) glide avalanche was reported from a N-NW slope below treeline. Additionally, steep south aspect slopes released loose wet avalanches in the afternoon.Last week, large persistent slab avalanches were reported on east to northeast aspects at all elevations, failing on the early-March and mid-March layers. There have been no reports of avalanches on these layers so far this week.

10-30 cm of new snow sits above a variety of crusts on all but high north aspects.In the south of the region, 70 to 90 cm of snow overlies two layers of surface hoar. The layers are most prominent on north to east aspects and were buried early-March and mid-March. In the north of the region, these layers are around 40 cm deep.Shallower parts of the region, such as the far north, have weak sugary facets near the bottom of the snowpack.
