    Recent snow (15-40 cm in past week) and previous strong winds have likely created wind slabs in lee alpine terrain. We don't have many observations from this area so watch locally for their development.

Avalanche Summary

No avalanches observed or reported in the past 24 hours in Little Yoho.

Snowpack Summary

15-40 cm of snow in past week (most around Lake Louise) overlies previous storm snow at upper elevations and rain-crusts below 1800 m. Recent strong winds have created wind-slabs in the alpine. The basal depth hoar is only a concern in shallow snowpack areas. Lower elevations have a temperature crust on all aspects.

Weather Summary

Friday: Light upslope winds and 2-4cm or more possible within convective cells. 1700-1900m freezing levels in the afternoon.

Saturday: A trough will begin to produce very light precipitation. Freezing levels 2000-2200m in the PM.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
