    New snow will begin to accumulate as it is accompanied with moderate to strong winds. Deposits will build on already present stubborn wind slabs.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Use ridges or ribs to avoid areas of wind loaded snow.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid freshly wind loaded terrain features.

Avalanche Summary

No recent avalanches have been reported, but observations are limited this time of year. Incoming new snow and wind are likely to change this over the next coming days. If you head out in the backcountry please support your community by submitting a MIN report!

Snowpack Summary

Relatively small amounts of new snow will be falling on the current snowpack over the next couple of days. Wind will accompany this snow and transport it onto a snowpack that has already been heavily wind-affected. Established stubborn wind slabs can be found on all aspects. Sustained cold temperatures have likely softened the snow surface in wind-sheltered terrain. Roughly 70 to 90 cm can be found at the treeline in White Pass and upwards of 100 cm may exist in wind-loaded areas. The lower snowpack consists of soft, sugary facets and a crust near ground level.
