Persistent slab avalanches remain possible on north-facing alpine slopes, particularly where the snowpack is thin and rocky.
It remains possible to trigger avalanches on buried weak layers, particularly where they are shallow in the snowpack and/or do not have a thick crust above them.
It's been several days since any avalanche activity was reported. The last known event was a sledder-triggered slab on Friday east of Wasa (see photo).
About 5 cm of recent snow sits above a hard melt-freeze crust on northerly alpine slopes. Elsewhere, a thick crust caps the surface. This crust will likely soften during the day and refreeze overnight.
The bottom half of the snowpack is generally weak and faceted
Lower elevations are melting rapidly.
