Points saillants

Currently a fairly stable snowpack with isolated areas of wind slab that sits on a weak surface hoar layer that will become more reactive with expectations of increasing snow and wind today.

    New and existing snow will become more of a problem with any significant accumulations around 4 inch plus.

Avalanche Discussion

In the Selkirks yesterday we found decent sliding conditions with some challenging areas due to the dust on crust scenarios.  The bond is weak to the ice crust with the surface hoar layer just above it creating more of a problem as it is going to be something for any significant snow load or wind slab to fail on.  Expect these to get tested today.
