Wind slabs will continue to develop on Tuesday. Use caution when entering lee and cross-loaded terrain.

Summary

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed today.

Snowpack Summary

Wind slabs are present in the Alpine and you could see some wind transport on Tuesday with the strong NW winds. Be especially aware on lee features and cross loaded slopes. 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.

Weather Summary

Tuesday will start off cool at -14c and warm up to -3c. Skies will be mostly sunny with some cloud. The winds are forecast to be strong from the NW.

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.
