Points saillants

Still pretty good skiing right now. The thing to watch will be the incoming wind. Its K-Country, we know they are coming, but we don't know exactly when. Keep your eyes open for it.

    Pockets of wind slab can be found in lee and cross-loaded terrain. Some of these are very dense, hard slabs. When the winds pick up, expect new slabs to form quickly.

    There seems to be lots of variability with this layer. As always, thin areas transitioning to localized wind loaded pockets will be more sensitive.

Snowpack Summary

A hint of wind last night moved some snow around up high which created a few non-reactive windslabs. We seem to have a slightly different snowpack in each drainage. In the Hero's Knob area the new snow rests on a solid mid-pack made up of either a windslab, or a thick re-frozen layer from the warm spell awhile back. In many places the crust is smooth and its easy to scrub off the storm snow. For now all the crusts are well settled and hard to trigger.

Weather Forecast

Avalanche Summary

Nothing new today.

Terrain and Travel

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
