    Small wind slabs may exist in alpine terrain.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Make observations and continually assess conditions as you travel.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

No new avalanches have been reported in this region but we expect that small wind slab avalanches likely occurred on Friday.

Snowpack Summary

By Saturday morning 5 to 10 cm of snow could overlie the late January surface hoar/crust layer. This new snow has been accompanied by strong to extreme west wind, meaning that the crust is still on the surface on southerly aspects and deeper deposits will be found on east aspects

The late January surface hoar is largest on sheltered treeline and below treeline features and may not exist on exposed terrain in the alpine.

The mid and lower snowpack is well settled.
