Avalanche Forecast
Regions: Little Yoho.
We are pressed under a cold Arctic airmass with rock bottom temperatures. Consider the risk of prolonged exposure in the event of even a small incident and plan accordingly.
Confidence
High
Avalanche Summary
No avalanches were observed reported today.
Snowpack Summary
25-30cm of settled storm snow from last week has been redistributed by the wind in exposed locations, burying the Jan 30 weak layer. The mid and lower snowpack is well settled, with tree-line snow depths ranging from 120 cm to 180 cm.
Weather Summary
Tomorrow's temperatures will remain as cold as today, with only a gradual warming trend through the coming week. The wind will stay light from the North, maintaining the influence of the Arctic air mass. No snow is expected, though some cloud cover may develop in the afternoon.
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.
Avalanche Problems
Wind Slabs
Winds have created a layer of hard windslab in many alpine lee features and moved snow in open areas at treeline. The wind transport has contributed to slab development with potential failure planes in the storm snow, at the Jan 30 facets, sun crusts, and isolated surface hoar.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
