Regions: Kananaskis.

A small pulse of snow shouldn't elevate the danger rating to much. As always, watch your exposure to overhead terrain and enjoy the great skiing.

Confidence

High - The number, quality, or consistency of field observations is good, and supports our confidence.

Weather Forecast

A small pulse of snow is expected to start this afternoon and in to Sunday morning. Approx 14cm. Winds will remain in the 30-40km range while the snow is falling and taper off by noon. The temperatures will drop drastically Sunday evening to -25. Luckily the day will remain reasonably warm around -15

Avalanche Summary

No new observed today

Snowpack Summary

Teams travelled in to the alpine today up to 2500M. No wind effect noted in our travels, however variable winds were constant today and fresh transport was observed in the alpine and off ridges.

The Dec 1st crust is down roughly 60cm and is starting to slowly facet out. No notable results as of yet, but continue to watch this layer morph and change as the season progresses.                          

Terrain and Travel

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.

Avalanche Problems

Wind Slabs

Reverse winds out of the North today saw some possible reverse loading on S-SW slopes. you can expect to find fresh windslabs in immediate lee features and cross loaded slopes. These don't seem to extend very far in to the terrain right now.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1.5 - 2
