Slightly warmer temperatures and new snow may increase the reactivity of persistent slabs
Avalanches are possible where the upper snowpack whumpfs, cracks or feels slabby under your feet
Human triggered avalanches are possible where a slab has formed above a weak layer of surface hoar, facets, and/or crust buried at the end of January about 30 to 70 cm deep.
On Wednesday no new avalanches were reported.
Rider triggering remains possible where a stiffer slab exists above the late January buried weak layers.
If you head into the backcountry consider submitting a MIN post!
30 to 70 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects. Exposed terrain in the alpine and treeline is variably wind-affected creating a stiffer slab above the weak layer. In turn, the stiffer slab may be easier to trigger under the weight of a human.
The mid and lower snowpack is generally well settled.
