Large persistent slab avalanches may remain possible to human trigger on steep slopes in the alpine.
Choose conservative terrain and watch for clues of instability.
Weak layers of facets and/or surface hoar are buried 30 to 70 cm deep. They are most prominent on alpine features sheltered from the wind.
Naturally triggered wet loose avalanches may occur in steep terrain during the heat of the day. Cornices also weaken and could release naturally. These could step-down to deeper layers, resulting in large avalanches.
No new avalanches were reported in this region on Thursday.
Please consider sharing your observations to the Mountain Information Network.
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.
Numerous large persistent slab avalanches were reported last week on a weak layer of surface hoar down 30 to 70 cm.
Cornices are large and looming at this time of year.
