Yukon, Tutshi, Wheaton, White Pass East, White Pass West.

Watch for wind-loaded pockets especially around ridgecrests and in extreme terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in this region on Saturday. However, field observations are currently very limited in this region.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Predominantly wind affected snow surfaces are found in the alpine.

Wind-sheltered terrain may hold settled soft snow that can produce dry loose avalanches with skier traffic in steep terrain.

Steep sun-exposed slopes may become moist with daytime warming and freeze into a crust overnight.

Cornices are large and looming at this time of year.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be alert to conditions that change with aspect and elevation.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
