In sintesi

New snow, strong wind and warming temps may increase the danger rating if more snow falls than forecasted.

    Strong winds this past week have created new windslabs in the upper snowpack.

  • Deep Persistent Slabs

    Thin areas are locations where it is more likely to trigger this weakness.

Confidence

Avalanche Summary

No new avalanches observed or reported today. Limited visibility in the spray valley.

Snowpack Summary

Recent snow continues to be transported around at treeline and above by strong to extreme westerly winds creating windslabs 40-60cm thick in lee features. As you transition into these areas be looking for these problems. These windslabs are overlying a generally well settled snowpack

The deep persistent weakness is buried deep in the snowpack down 150-170cm. This layer was active as recently as last week being triggered from a thin shallow snowpack area. Always be curious about snowpack depths and be thinking how the snow has been moved around creating thin areas.

Below 2100m a layer of surface hoar (spotty distribution) is down 40cm and may be a concern as the snowpack settles with the incoming warmer temps.

Weather Summary

Monday: Varying models show a storm moving in, 10-20cm of snow., day time high of -3. The wind will be strong to extreme out of the West. Freezing levels to rise to 1900m

Terrain and Travel Advice

  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.
  • Be careful as you transition into wind-affected terrain.
  • Watch for areas of hard wind slab on alpine features.
