- 1–1.5
Wind slabs can be found in isolated locations in the alpine. These developing wind slabs are small in size but be aware that if triggered, they could trigger a persistent slab.
Good skiing can be found out there, however watch for windslabs near ridgetop and persistent slabs on northerly aspect.
If the sun comes out and it warms up, wet loose avalanches will be possible during the heat of the day.

This problem seems to be most active where the March 19th crust is not supportive over the Feb 3rd weak layer (down 30-90cm) of facets over a crust. Northerly aspects between 1900-2400m seem to be the problem area. It is possible that this will step down to the deep persistent weak layer.
Climbing freezing levels and solar radiation will destabilize the snowpack. Loose wet avalanches are most likely on steep, sun affected slopes. Avalanches may initiate easily on the smooth crust below.
No new avalanche activity reported on Saturday.
10-15cm of low density snow sits over the March 19th crust which is present everywhere except North aspects above 1900m. The Feb 3rd crust interface is down 30-90cm. Basal depth hoar and facets make up the bottom of the snowpack. HS ranges from 50 to 150cm.
