Regions: Little Yoho.

Snowpack slowly adjusting, but human triggering remains a risk.

Avalanche control is being conducted on Mt. Field, Mt. Dennis and Mt. Stephen Wednesday Feb 26. These areas are CLOSED.

Confidence

Moderate

Avalanche Summary

No avalanches were observed or reported in Little Yoho today. However, check avalanche summary in adjacent Banff forecast for a report of a skier accidental today near Lake Louise.

Snowpack Summary

30-35 cm of well settled storm snow at treeline with mild temps and strong S-SW winds helping to form new wind and storm slabs. This snow sits over a layer of weak facets, surface hoar or sun crust from the cold snap.

The mid and lower snowpack is mostly well-settled, though it is heavily facetted in thin snowpack areas. Tree-line snow depths range from 120 cm to 180 cm.

Weather Summary

Valley temperatures will hover just below freezing, with ridge temperatures warming to -6°C by Wednesday afternoon. Expect minimal snowfall with persistent cloud cover. Winds will be strong and sustained from the west.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Loose avalanches may step down to deeper layers, resulting in larger avalanches.

Avalanche Problems

Persistent Slabs

Up to 30 cm of storm snow and strong S-SW winds have loaded lee areas at treeline and above with new slabs up to 60 cm deep. This is sitting on a weak layer of facets, surface hoar or sun crust. Human triggering will remain likely in steep or wind loaded terrain for the next few days.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5
