Avalanche Summary
No new avalanches were reported in Little Yoho. In the adjacent Banff region, some small wind slabs (up to size 1.5) were reported with explosives at the Sunshine ski area, and some very small, loose, dry avalanches in extreme terrain triggered by the sun.
Snowpack Summary
25-30cm of settled snow from last week has been redistributed by the wind in exposed locations, burying the Jan 30 weak layer, and in isolated locations formed now what are aging wind slabs. Specific areas exposed to the wind may have strastrugi. The mid and lower snowpack is well settled, with tree-line snow depths ranging from 120 cm to 180 cm.
Weather Summary
Sunday: 2-4 cm of snow, light SE winds and treeline temperatures around -15C. No significant snow in the forecast.
Terrain and Travel Advice
- Be careful as you transition into wind-affected terrain.
- Wind slabs are isolated, but may remain reactive.
- Closely monitor how the new snow is bonding to the old surface.
Problems
Wind Slabs
Lingering hard wind slabs exist on alpine lee features. Potential failure planes are old weak facet layers or the Jan 30 layer of facets, sun crusts, and isolated surface hoar beneath the recent snow.
