Lo esencial

Up to 10 cm of low density new snow is sitting on the surface. Once the wind picks up again, expect to see new thin wind slab development in lee terrain. In the meantime stay warm out there.

Confidence

High - We have a good understanding of the snowpack structure and confidence in the weather forecast

Avalanche Summary

There have been no reports of recent avalanche activity.

Snowpack Summary

The snow surface likely consists of 5-10 cm low density of new snow sitting on top of old wind slabs in open terrain and some soft pockets in sheltered terrain.

A buried weak layer of surface hoar may still be found around 90 cm deep. It was found around Log Cabin and also in Powder Valley (see here). Avalanche activity on this layer hasn't been reported since the first week of January and isn't expected to spike without a substantial snowfall or warming trend.

The lower snowpack is strong around White Pass but a thinner and weaker snowpack structure is expected inland, such as in the Wheaton Valley and the south Klondike.

Terrain and Travel

  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Be carefull around freshly wind loaded features.
