Buried windslabs are still apparent in the alpine, but sheltered areas at treeline offer the best skiing right now. Happy hunting!

Weather Forecast

Tomorrow we will have the mixed blessing of a significant warming trend. The daytime high will be -3C. I say mixed because we may see a sun crust develop, and possibly even a warming avalanche cycle. This all hinges on if the sun comes out or not. In other weather news, flurries will hopefully roll through and give a few centimeters and winds will remain light. We are expecting 10-15cm by Tuesday.

Avalanche Summary

Nothing new today. 

Snowpack Summary

Lots of buried windslabs out there right now. Overall we have really good coverage, but at times today we caught ourselves saying how loaded some alpine slopes look. These slopes all have multiple layers of windslabs that are so far sticking together and seemingly OK. We do have the voice in the back of our heads that warn of the Feb 14th facet layer and the Jan 29 hard slab layers. These are down 60cm and 100cm respectively, and worth having a look at.

Terrain and Travel

  • Watch for areas of hard wind slab on alpine features.
  • Avoid lee and cross-loaded terrain.
  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.

Avalanche Problems

Wind Slabs

Convex areas and freshly buried thin areas are common places to find the more triggerable slabs. We have enough coverage now for the cross loaded gullies to blend together into what appears to be large open slopes. Watch for thin spots if traveling through these areas.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1.5 - 2.5
