Large persistent slab avalanches may remain possible to human trigger in the alpine.
Avoid steep or convex slopes where triggering slabs is more likely.
A few large slab avalanches were recently reported on a variety of aspects on steep alpine slopes. They likely failed on either a crust or a weak layer of surface hoar down 30 to 70 cm.
Numerous recent wet loose and slab avalanches up to size 2.5 were reported on a variety of aspects in the alpine on Saturday.
The slab avalanches likely failed on either a crust or a weak layer of surface hoar, depending on the aspect of the slope. Strong solar radiation often increases the likelihood of triggering both loose and slab avalanches. See MIN 1 and 2.
A mix of wind affected and soft snow can be found in the alpine. Sunny aspects have a crust on the surface that may soften with daytime heating.

Cornices are large and looming at this time of year.
