Large persistent slab avalanches may remain possible to human trigger at treeline and above.
Avoid steep or convex slopes where triggering slabs is more likely.
In isolated locations, a weak layer of facets and/or surface hoar is down 50 to 100 cm. It is most likely to be in terrain sheltered from the wind at treeline and above.
A few naturally triggered wind slab avalanches up to size 2 were reported on a variety of aspects in the alpine on Friday.
Field observations are currently very limited in this region. Please consider sharing your observations to the Mountain Information Network.
A hard melt-freeze crust exists on the snow surface on sun-exposed slopes to the mountain tops. The crust will transition to wet snow with daytime warming and generally re-freeze at night.
Dry snow may still be found on true north aspects at upper elevations.
In isolated locations, a weak layer of facets and/or surface hoar is down 50 to 100 cm. It is most likely to be in terrain sheltered from the wind at treeline and above.
