Avalanche Forecast
Regions: Little Yoho.
The deep persistent problem has been removed from the forecast region due to the absence of recent avalanche activity. However, the layer remains in the snowpack and could re-emerge as a concern in the future. Wind could increase Tuesday in the high alpine.
Confidence
Moderate
Avalanche Summary
No avalanches were observed or reported in Little Yoho today.
Snowpack Summary
Wind slabs remain on lee features in the alpine. The upper pack may have a thin crust under the new snow on solar aspects and a surface hoar/facet interface under last week's snow, but no avalanches observed on this layer yet. The mid-pack is generally strong; however, a facet layer can be found near the ground in shallow snowpack areas. At treeline, average snowpack depth ranges from 120 to 150 cm.
Weather Summary
Generally clear weather is expected on Monday, with slightly warmer temperatures. Valley temperatures will be around -7°C, and ridge temperatures near -10°C. A slight temperature inversion is also possible. Winds at 3000m may increase into the strong range from the NW.
Terrain and Travel Advice
- Wind slabs are most reactive during their formation.
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
Avalanche Problems
Wind Slabs
Generally light winds today, combined with cool alpine temperatures, have had minimal impact on wind slab formation. However, wind slabs remain present in alpine lee areas. Exercise caution in wind-loaded terrain, especially near ridges, convex slopes, and leeward features.
Aspects: All aspects.
