    Wind slabs exist on lee and cross-loaded features and are expected to build further over the next few days.

    A cohesive slab sits over a weakness buried in mid-December. Avalanche activity on this layer has slowed down, but it could reawaken as new snow loading builds up.

Confidence

Fair - Timing, track, or intensity of incoming weather is uncertain

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

The recent storm snow seems to be settling and strengthening. Any loose available snow continues to be redistributed by southwest winds. Wind slabs with the potential to propagate widely exist in the alpine, particularly on north through east aspects. At treeline and below, pockets of wind slab also exist in open areas. A surface hoar/facet/crust interface is buried anywhere from 40- 80cm deep. Avalanche activity on this layer has slowed, but it remains a concern as snow-loading gradually builds this week. Sudden ('pops') type results were observed on this layer earlier in the week.A sun crust is also buried in the alpine on some steep south and west aspects. The mid-pack is generally strong and well settled.
