    This slab is sitting on the October crust which has facets above it and provides a good sliding surface. It is more reactive on N and E aspects.

Weather Summary

Temperatures have warmed up with a bit of an inversion. The alpine should reach -1c. Skies are expected to be a mixed bag of sun and cloud with moderate NW winds.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.

Avalanche Summary

No new avalanches have been observed today.

Snowpack Summary

Wind slabs are present in more specific features in the alpine such as lee features and cross loaded slopes/gullies. Approach the alpine with this in mind. The height of snow varies from 40cm of facets to 70cm of more consolidated snow. Early season hazards are all over the place at all elevations. The October crust is close to the ground and has started to break down with facets just above it. This is our layer of concern and would provide a good sliding layer if triggered at the right spot.
