Both recent and older wind slabs have proven to be reactive during testing and could therefore also be reactive when skiers pass over them. They still need time to stabilise. Favour safe travel techniques and plan your outing according to the danger ratings to make the most of tomorrow's sunny day.
Recent wind slabs on the NE, E, SE, and S slopes vary in thickness from 10 to 40 cm. These could be reactive to skiers' movements and need time to stabilise. Older slabs beneath the recent ones could also be reactive.
No new avalanches have been observed or reported.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
In the alpine and at treeline, conditions are highly variable, with wind-hardened snow, pockets of powder, wind slabs of varying densities, and areas scoured down to bare ground, particularly on west-facing slopes.
Below treeline, 20 to 40 cm of light snow overlies a progressively denser snowpack, down to basal weak layers of faceted grains and depth hoar.
On solar aspects, a sun crust is present 5 to 30 cm below the surface.
At mid-elevation, the average snowpack depth is around 130 cm.
